## [26.06rc1] - 2026-05-11: "CODENAME"

### Added

 - JSON-RPC: `graceful` command to prepare CLN for shutdown. ([#9111])
 - JSON-RPC: `xkeysend` command for keysend with modern routing support. ([#9110])
 - JSON-RPC: `sendamount` command, to make a payment specifying the desired amount to send instead of the amount to be received. ([#None])
 - JSON-RPC: `askrene-remove-channel-update`, a new RPC to remove channel_update entries from layers. ([#9040])
 - Plugins: `invoice_creation` notification now includes `offer_id` when the invoice is associated with a BOLT 12 offer. ([#8981])
 - Config: option `xpay-user-layer` to add default layer(s) to `xpay` ([#9037])
 - JSON-RPC: `sendpay` now accepts one of the `paths` returned from `getroutes` as its `route` parameter. ([#9110])
 - JSON-RPC: `getroutes` `route` explicit fields `node_id_in`, `node_id_out`, `amount_in_msat`, `amount_out_msat`, `cltv_in`, `cltv_out`. ([#9110])
 - Protocol: `xpay` now uses shadow CLTV additions to help mask final destination as per BOLT 7. ([#9110])
 - Protocol: `xpay` will now update for the current payment if it gets a `channel_update` in an error message. ([#9110])
 - JSON-RPC: `xpay` now accepts `label` and `localinvreqid` parameters (like `pay`). ([#9110])
 - JSON-RPC: `injectpaymentonion` parameter `destination`. ([#9110])
 - Tracing: Add a unix-domain socket sink for opentelemetry traces ([#9078])


### Changed

 - Protocol: `message-padding` defaults to false, due to poor detection of broken implementations. ([#9119])
 - JSON-RPC: `xpay` now handles `pay` command by default (use `xpay-handle-pay=false` to prevent this) ([#9110])
 - JSON-RPC: `pay` now accepts `invstring` as a parameter name for `bolt11`, to ease transition when xpay takes over in v27.03. ([#9110])
 - offers: we now use `xpay` not `pay` for paying invoices made with invoicerequest(). ([#9110])
 - JSON-RPC: `getemergencyrecoverdata` is now more verbose. ([#8422])
 - Build: We no longer use `-Werror` by default, unless --enable-debugbuild is set. ([#9101])
 - Protocol: We now wait 72 blocks, not 12, before closing channels (BOLT update) ([#9051])


### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - JSON-RPC: `keysend` (use `xkeysend`).  `xkeysend` will take over `keysend` in v27.03. ([#9110])
 - JSON-RPC: `getroute` (use `getroutes` with layers `["auto.localchans","auto.sourcefree"]` and `maxparts=1`) (available since v25.09). ([#9110])
 - JSON-RPC: `pay` and `paystatus`: use `xpay`, `listpays` (or `xpay`'s notifications for details of attempts).  `pay` will be replaced by `xpay` in v27.03. ([#9110])
 - JSON-RPC: `getroutes` `route` fields `next_node_id`, `amount_msat` and `delay` (use `node_id_out`, `amount_in_msat` and `cltv_in`). ([#9110])
 - JSON-RPC: `getroutes` layer `auto.no_mpp_support`: use `maxparts=1` parameter instead (available since v25.09). ([#9110])


### Removed

 - JSON-RPC: `exclude` parameter to `pay` (when `xpay-handle-pay` is True): craft a layer with desired modifications and pass it to `xpay` `layers`. ([#9110])


### Fixed

 - Protocol: high fee issue that caused `splicein` and `spliceout` to abort. ([#9109])
 - JSON-RPC: `setconfig` no longer crashes on dynamic multi-value plugin options ([#8751])
 - contrib: the systemd lightningd.service script now shuts down lightningd properly. ([#9111])
 - JSON-RPC: `xpay` now correctly returns error code 219 on already paid invoices (not 218). ([#9110])
 - JSON-RPC: `withdraw` now returns a fully signed transaction in the `tx` response field. ([#8942])
 - Wallet: Transactions now correctly create change outputs >= 330 sat for P2TR/P2WPKH instead of absorbing them as fees ([#8807])
 - Protocol: we now only store the most recent peer backup when recovering from peers. ([#8422])
 - JSON-RPC: `fundchannel_complete`: reject PSBTs with unsigned non-segwit inputs (could lead to unrecoverable funds!). ([#8922])
 - Protocol: `gossipd` will now silently ignore gossip for other chains (rather than sending warnings). ([#9044])
 - Protocol: when we send errors, we won't include a `channel_update` if we chose a different channel than the one they told us to. ([#9044])
 - Protocol: use BOLT4's paranoid advice about doing constant-time error decryption. ([#9044])
 - Fix for `splicein`, `spliceout`, and `dev-splice` commands where channel balances included partial sats. ([#9097])
 - build: fix build errors with GCC 15 (Arch Linux). ([#9075])


### EXPERIMENTAL

 - JSON-RPC: `createproof` to create a payment proof for a (successful) BOLT12 payment. ([#9116])
 - JSON-RPC: `decode` now supports the `lnp` payer proof format. ([#9116])

## [26.04.1] - 2026-04-25: "Negative Routing Fees II"

This point release is recommended: it fixes a build failure in some environments and a gossip protocol issue.

### Fixed

 - **Protocol:** we now reject `channel_announcement` messages where `node_id_1` is not lexicographically less than `node_id_2` (per BOLT; see [lightning/bolts#1333](https://github.com/lightning/bolts/pull/1333)), so malformed announcements no longer stress the gossip store and other readers. ([#9082])
 - **Build:** correct `printf` format for splice weight logging (`%zu` for `size_t` in `lightningd`, `channeld`, and the spender plugin), fixing `-Werror` / `-Wformat` failures (e.g. Docker and 32-bit ARM cross-compiles). ([#9083], [#9086])
 - **Build:** bookkeeper no longer uses `__int128` for currency rate math, so 32-bit targets build again. ([#9085])

([#8938])
 - lightningd: we don't allow new incoming channels if we cannot estimate fees (rather than assuming minfee). ([#8864])
 - Plugins: `sql` plugin tables "htlcs", "forwards", "invoices", "sendpays" and "networkevents" are now updated more efficiently. ([#8914])

 - JSON-RPC: `close` `tx` and `txid` field (use `txs` and `txids`), deprecated v24.11. ([#8850])
 - JSON-RPC: `decodepay` (use `decode`), deprecated v24.11. ([#8850])

 - Plugins: `bkpr_listbalances` no longer crashes if we lost our db, then do emergencyrecover and close a channel. ([#8890])
 - lightningd: possible crash when peers disconnected if there was more than one plugin servicing the `peer_connected` hook. ([#8889])
 - reckless search now returns partial matches instead of requiring exact plugin names. ([#8762])
 - JSON-RPC: `enableoffer` returns an error when trying to activate an used single use offer (don't crash!) ([#8813])
 - JSON_RPC: `getroutes` fixed a class of corner cases that cause askrene main loop to timeout instead of quickly failing, thus wasting runtime. ([#8866])

 - JSON-RPC: `autoclean-once` returns "uncleaned" number reflecting number of candidates which were too new to be cleaned, not all records we didn't delete. ([#8651])
 - JSON-RPC: `invoice` no longer accepts 640-byte descriptions (it would produce malformed invoices). ([#8535])
 - Protocol: `keysend` with descriptions of length 640-1023 bytes fixed. ([#8535])
 - JSON-RPC: `listtransactions` now correctly updates `blockheight` for txs created by `sendpsbt` which have no change outputs. ([#8555])
 - pytest: Tests that require Rust no longer fail if Rust is disabled. ([#8491])
 - Protocol: fix occasional lost sending of final packet (usually warnings or errors). ([#8570])
 - JSON-RPC: `keysend` command no longer corrupts the type numbers of extra TLVs when they are specified as numeric strings longer than 2 digits. ([#8413])
 - Fix out-of-bounds error when handling 255-byte DNS names. ([#8325])
 - pyln-client no longer leaks a file descriptor when connecting to an RPC socket with a long path name. ([#8488])
 - Protocol: Fixed hash calculation inconsistency when processing invoices with unknown fallback address versions. ([#8302])
 - Integration tests no longer fail when run in a deeply nested directory on Linux. ([#8492])
 - Build: we can now build without sqlite3 support. ([#8561])
 - Build: Fedora releases are also deterministic now. ([#8692])
 - Docker: Core lightning version in Docker image will not be missing. ([#8659])

### EXPERIMENTAL

 - Splicing BREAKING change - spec changes mean peers must upgrade in unison! (`commitment_signed`s splice_info tlv's and `channel_reestablish` changed) ([#8646], [#8506])
 - Protocol: stricter conformance to Bolt spec for splice commitments. ([#8463])
 - Config: `experimental-lsps-client` and `experimental-lsps2-service` support for LSPS level 2 specification ([#8569])
 - Protocol: specification for recurring offers changed: old recurring offers will no longer work. ([#8398])
 - Protocol: BOLT 12 recurrence `start\_any\_period` removed, use expiry if you need to restrict when they can start using the offer. ([#8398])
 - Protocol: BOLT 12 recurrence `years` removed; use 12 x months. ([#8398])
 - Splicing: Fixed crash when we splice a channel which hasn't been announced yet. ([#8555])
 - JSON-RPC: `cancelrecurringinvoice` command to send new "don't expect any more invoice requests" msg to recurring bolt12 invoices. ([#8398])

## [25.09.3] - 2025-11-06: "Hot Wallet Guardian IV"

### Fixed

 - Docker image was missing SQLite library

[#8667]: https://github.com/ElementsProject/lightning/pull/8667
[25.09.3]: https://github.com/ElementsProject/lightning/releases/tag/v25.09.3

## [25.09.2] - 2025-11-04: "Hot Wallet Guardian III"

`Bookkeeper` and `xpay` users: please upgrade!
This point release includes fixes for `xpay`, `bookkeeper` and optimizations for large nodes using `bookkeeper`. 

### Changed

 - plugins: the sql plugin now keeps an index on `channelmoves` by `payment_hash`. ([#8618])
 - plugins: `bookkeeper` reduced logging for large imports to increase speed. ([#8657])
 - plugins: `sql` initial load for tables is much faster (e.g 82 to 17 seconds for very large channelmoves table). ([#8657])

### Fixed

 - Core lightning builds for Ubuntu Focal, Jammy and Noble are deterministic again. ([#8547])
 - Reproducible build for Ubuntu noble by updating sqlite3 version and shasums. ([#8551])
 - plugins: bookkeeper first invocation after migration from prior to 25.09 with very large databases will not crash. ([#8618])
 - `xpay` would sometimes leave payment parts status `pending` in failure cases (as seen in listpays or listsendpays). ([#8635])
 - Plugins: `askrene` could enter an infinite loop when maxparts is restricted. ([#8636])
 - plugins: `bcli` would fail with "Argument list too long" when sending a giant tx. ([#8639])
 - JSON-RPC: Dealing with giant PSBTs (700 inputs!) is now much faster. ([#8639])
 - plugins: assertion crash in bookkeeper when fresh records arrive while multiple queries in progress. ([#8642])
 - Plugins: `bookkeeper` now correctly restores chain event blockheights it has derived. ([#8649])

## [25.09.1] - 2025-10-15: "Hot Wallet Guardian II"

Several important fixes, please upgrade!

### Added

 - added verification of GPG keys for the bitcoin and litecoin tarballs. ([#8429])

### Changed

 - lightningd: we defer deletion of old htlcs on channel close, to avoid pausing for a long time (we clean them on startup) ([#8563])
 - gossipd: add gossip_store recovery for filesystems which do not synchronize read and write (e.g. ZFS on Linux), by disabling mmap reads and rewriting the last records. ([#8566])
 - Dockerfile: improve build time and reduce image size ([#8429])

### Fixed

 - JSON-RPC: `listchainmoves` could contain bogus duplicate entries after 25.09 bookkeeper migration. ([#8574])
 - bookkeeper: failed reload of rebalances on restart. ([#8562])
 - fixed compilation on all target architectures; each had their own bugs (poetry, missing packages...). ([#8429])
 - fixed cargo cross compilation. it was mistakenly using QEMU before. ([#8429])
 - fixed CPU compatibility bug described in issue 8456 ([#8429])
 - lightningd: potential crash when we receive a malformed onion complain from our first peer when using sendonion / injectpaymentonion. ([#8597])
 - db: migration from v25.09 on a reasonable size account database could take almost infinite time. ([#8587])
 - pyln-testing: restore compatibility with pre-25.09 CLN versions. ([#8539])
 - build: we now build on MacOS without errors on the latest Command Line Tools (macOS 15 SDK). ([#8599])

## [25.09] - 2025-09-01: "Hot Wallet Guardian"

This release named by @king-11.

Note: release schedule moved one month: this is v25.09, and all deprecations incremented accordingly. ([#8370])

### Added

 - JSON-RPC: `xpay` can now directly pay a BIP353 address, like `₿rusty@rustcorp.com.au`. ([#8467])
 - JSON-RPC: `xpay` can now pay a simple offer directly, rather than requiring fetchinvoice first. ([#8467])
 - JSON-RPC: `listchainmoves` and `listchannelmoves` commands to access the audit log of coin movements. ([#8410])
 - `reckless` can now install python plugins using the uv package manager. ([#8430])
 - JSON-RPC: `getroutes` new parameter `maxparts` to limit the number of routes in the solution. ([#8448])
 - Plugins: `openchannel` and `openchannel2` hooks now expose the `channel_type` field for the offered channel. ([#8454])
 - Plugins: The `htlc_accepted_hook` now gets the TLV-stream ([#8433])
 - Plugins: `xpay` now publishes `pay_part_start` and `pay_part_end` notifications on every payment send attempt. ([#8354])
 - JSON-RPC: `sql` also supports functions `json_object(key1, value1, ...)` to construct JSON objects and `json_group_array(value)` to aggregate rows into JSON array. ([#8446])
 - clnrest: can now return successful responses as xml, yaml, or form-encoded in addition to json defined in the 'Accept' header. The same goes for request types defined in the 'Content-type' header. ([#8383])
 - JSON-RPC: `getroutes` now performs better when using the "auto.no_mpp_support" layer (for forced single-part payments) ([#8299])
 - contrib/log_visualizer.html: A new tool for rendering CLN log files in the browser. ([#7725])
 - hsmtool: new `derivetoremote` method. ([#7344])
 - JSON-RPC: `sql` plugin now supports `chainmoves` and `channelmoves` tables. ([#8410])
 - JSON-RPC: `wait`: new subsystems `chainmoves` and `channelmoves`. ([#8410])
 - Plugins: `channel_hint_update`, `pay_failure` and `pay_success` notifications now have objects of the same name containing the expected fields. ([#8376])
 - JSON-RPC: `coin_movement` notification `utxo` field. ([#8445])
 - JSON-RPC: `coin_movement` notification `spending_txid` field. ([#8445])
 - JSON-RPC: `coin_movement` notification `primary_tag` and `extra_tags`. ([#8445])
 - Plugins: `coin_movement` notification with `part_id` field now always has `group_id` field. ([#8445])


### Changed

 - Build: we now use `uv` to build instead of poetry: see doc/getting-started/getting-started/installation.md ([#8249])
 - Protocol: We now insist that peers support `option_channel_type` (in CLN since 0.12.0 in late 2022, similar for other implementations). ([#8389])
 - Protocol: payment secret ('s' field) is now mandatory in BOLT11 payment requests for improved security. ([#8377])
 - Protocol: Offers on nodes with only private channels are now payable (i.e. no more blinded path errors!). ([#8500])
 - wss-proxy.py was replaced by a rust version with support for multiple `wss-bind-addr`. If you install CLN from pre-compiled binaries you must remove the old wss-proxy directory first before installing CLN, usually ([#8080])
 - pyln-client: plugin notifications parameters now exposed directly, not wrapped in `params` object. ([#8376])
 - Plugins: `bookkeeper` now explicitly assumes every transaction is in the same currency as the node (true unless you added manually) ([#8445])
 - JSON-RPC: fundchannel / fundchannel_start returned `channel_type` will include option_zeroconf if it was implied by a 0 minimum_depth, even if we didn't explicitly ask for a zero conf channel. ([#8389])
 - build: we now require sqlite3 version 3.26 or above (released 2018-12-01). ([#8418])
 - Plugins: `bookkeeper` now uses the lightningd database, not "accounts.db". ([#8410])
 - libplugin: you can now call the synchronous API functions at any time (not just in the init callback). ([#8410])
 - Plugins: "utxo_deposit" notification is allowed to have missing `transfer_from`, and null is not considered an account name. ([#8410])
 - Plugins: `sql` tables `forwards`, `htlcs`, `invoices`, `sendpays` all use `created_index` as their primary key (and `rowid` is now an alias to this). ([#8410])
 - Rust: custom notifications fields no longer wrapped in `payload` object, and `origin` is now outside the `params` object ([#8376])


### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - Plugins: `channel_hint_update`, `pay_failure` and `pay_success` notification fields outside the same-named object. ([#8376])
 - pyln-client: plugin custom notifications `origin` and `payload` (use parameters directly) ([#8376])
 - JSON-RPC: `coin_movement` notification `utxo_txid`, `vout` and `txid` fields (use `utxo` and `spending_txid`). ([#8445])
 - JSON-RPC: `coin_movement` notification `tags` array (use `primary_tag` and `extra_tags`). ([#8445])


### Removed

 - Protocol: backwards compatibility allowances for CLN before 23.08 which didn't handle `option_scid_alias` properly. ([#8389])
 - Config: `experimental-anchors` and `experimental-onion-messages` (deprecated 24.02 / 24.08, disabled v25.05). ([#8352])
 - JSON-RPC: `commando-rune`, `commando-listrunes`, `commando-blacklist` (deprecated v23.08, disabled v25.05). ([#8352])
 - Config: autodetection for rest-port/rest-protocol/rest-host/rest-certs options to clnrest-* (deprecated v23.11, disabled v25.02). ([#8352])
 - Config: `max-locktime-blocks` (deprecated v24.05, disabled v25.02). ([#8352])


### Fixed

 - Certificates auto-generated by grpc-plugin, rest-plugin, and wss-proxy-plugin now include the required Authority Key Identifier and Key Usages extensions. ([#8495])
 - JSON-RPC: `fetchinvoice` is now more reliable. ([#8470])
 - lightningd: don't get confused with parallel ping commands. ([#8344])
 - libbacktrace works with macOS, so we get backtraces on crashes ([#8431])
 - Protocol: trying to create a channel below our own min-capacity-sat will now fail before asking the peer, not with an error blaming the peer when they accept! ([#8468])
 - Config: the node no longer crashes if you set `watchtime-blocks` to 0 (which is fine for testing: don't do this on mainnet!). ([#8436])


### EXPERIMENTAL

 - Protocol: support for `start_batch` in splicing makes us Eclair compatible! ([#8335])
 - Protocol: we now allow routing through old short-channel-ids once a splice is done (previously we would refuse, leading to a 6 block gap in service). ([#8387])
 - Config: Removed the non-functional `experimental-upgrade-protocol` config option. ([#8377])

## [25.05] - 2025-06-16: "Satoshi's OP_RETURN Opinion"

This release named by Peter Neuroth (@nepet).

**WARNING**: `--experimental-splicing` is incompatible with previous CLN versions!  You will not

## [25.02] - 2025-03-04: "Onion Packet Filler Accreditation"

This release named by @s373nZ.

### Added

 - Plugins: `chanbackup` turns our peers into watchtowers and enables SCB to create penalty txns. ([#7772])
 - JSON-RPC: `fetchinvoice` BIP 353 name support (`bip353`). ([#7887])
 - JSON-RPC: `blacklistrune` now has an option to un-blacklist (`relist`). ([#8037])
 - JSON-RPC: `setconfig` now has a `transient` flag which means it won't rewrite your config file. ([#8095])
 - Plugins: New nofitications `plugin_stopped` and `plugin_started`. ([#7508])
 - xpay: `xpay-slow-mode` makes xpay wait for all parts of a payment to complete before returning success or failure. ([#8094])
 - Plugins: `xpay` now supports a `maxdelay` parameter for better `xpay-handle-pay` compatibility. ([#7969])
 - JSON-RPC: `listpeerchannels` new output fields `their_max_total_htlc_out_msat` and `our_max_total_htlc_out_msat` as the value of `max_htlc_value_in_flight` (as of BOLT02) set by the local and remote nodes on channel creation. ([#8084])
 - Config: Added support for Bitcoin `testnet4`. ([#7894])


### Changed

 - clnrest: clnrest is now a rust plugin. ([#7509])
 - JSON-RPC: `blacklistrune` no longer supports of runes over id 100,000,000. ([#8037])
 - Splicing: User is prevented from trying to splice unsigned PSBTs, protecting against potential issues. ([#8052])
 - Splicing: Stricter tests for interop with Eclair. ([#8031])
 - `xpay` now populates more fields, so `listsendpays` and `listpays` show `destination` and `amount_msat` fields for xpay payments. ([#7941])
 - `xpay` now gives the same JSON success return as documented by `pay` when `xpay-handle-pay` is set. ([#7938])
 - JSON-RPC: With `xpay-handle-pay` set, xpay will now be used even if `pay` uses maxfeeprecent or exemptfee parameters (e.g. Zeus.) ([#7942])
 - Release: Docker images are now based on Debian Bookworm. ([#7921])
 - lightning-cli: Plugin descriptions in `lightning-cli help` is now more readable with interpretation of \n characters. ([#8022])

 - Config: `rest-port`, `rest-protocol`, `rest-host` and `rest-certs` disabled by default (use `clnrest-*`, or `i-promise-to-fix-broken-api-user=rest-port.clnrest-prefix` etc and PLEASE REPORT if you need this!) ([#8089])
 - Config: `max-locktime-blocks` disabled by default (use `i-promise-to-fix-broken-api-user=max-locktime-blocks` and PLEASE REPORT if you need this!) ([#8089])


### Removed

 - lightningd: Tell plugins our bolt12 features (so our bolt12 invoices explicitly allow MPP). ([#8059])
 - lightningd: Allow more time for plugin startup so slow nodes don't time out on startup. ([#8060])
 - lightningd: Fixed onchaind crash when seeing unrelated txs (usually when catching up with old closes.) ([#8137])
 - `xpay`: Corrected the CLTV values in blinded paths which sometimes caused spurious failures. ([#8121])

 - JSON-RPC: low-level RPC command `addpsbtinput` to fund PSBTs directly and help with complex splices & dual-opens. ([#6980])
 - JSON-RPC: `stfu_channels` and `abort_channels` are added for bulk multi-channel splice commands. These allow the user to pause (and resume) multiple channels in place. ([#6980])

 - Build: Added architecture identifier to Ubuntu release ([#7797])
 - Logging: connectd now logs unknown messages as "UNKNOWN" not "INVALID" to avoid freaking people out. ([#7892])
 - Protocol: we now create a low-priority (2016 down to 12 blocks fee target) anchor for low-fee unilateral closes even if there's no urgency. ([#7832])
 - Protocol: splicing moved from test numbers to spec numbers. ([#7719])
 - Protocol: Support added for peers that wish to rotate their funding pubkey during a splice. ([#7719])

 - JSON-RPC: `splice_update` can in some cases now return the remotely partiall signed psbt to the user, if so `signtures_secured` will be true. ([#6980])
 - JSON-RPC: `splice_signed` parameters are switched in order to make `channel_id` an optional parameter, enabling multi-splice-signatures. ([#6980])
 - `pay`: Discarding an overly long or expensive route does not blocklist channels anymore. ([#7494])
 - Plugins: `cln-grpc` Upgrade tonic version and ([#7598])


### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

## [24.08.2] - 2024-10-18: "Steel Backed-up Channels"

This point release addresses few crash fixes and includes an enhancement to remember and update channel hints for payments.

### Changed

- pay: Now remembers and updates channel hints across payments ([#7494])
- pay: Discarding an overly long or expensive route does not blacklist channels anymore. ([#7494])
- grpc: Channel type `anchors/even` was added to the grpc bindings. ([#7628])

### Fixed
- gossipd: crash errors with large gossip_store (>4MB) growth on longer-running nodes. ([#7729])
- connectd: crash on erroneous timeout. ([#7736])
- Protocol: we could get confused on restart and not re-transmit our own channel_updates. ([#7737])
- rpc: `listpeerchannels` (and thus, pay) sped up on very large nodes. ([#7679])
- Improved pathfinding speed for large nodes. ([#7726])

## [24.08.1] - 2024-09-16: "Steel Backed-up Channels"

This hotfix release fixes few crash issues and some other bugs.

### Fixed

 - No longer crash if a plugin dies during lightningd startup. ([#7673])
 - Fixed crash when starting channeld for older channel with no local alias. ([#7664])
 - Will not crash for older pre-tlv peers where send_tlvs is NULL. ([#7650])
 - Compilation will fail gracefully if `jq` is missing or an outdated version is detected. ([#7662])
 - cln-plugin: Change default log level filter back to INFO ([#7668])
 - Fixed intermittant bug where hsmd (particularly, but also lightningd) could use 100% CPU. ([#7661])
 - Made `description` optional in `Wait(any)invoiceResponse` to handle BOLT12 ([#7667])
 - Removed bogus "**BROKEN** plugin-topology: DEPRECATED API USED: listchannels.include_private" message. ([#7663])

## [24.08] - 2024-08-28: "Steel Backed-up Channels"

This release named by @Lagrang3.

### Added

 - protocol: onion messages are now supported by default. ([#7455])
 - protocol: onion messages can now be forwarded by short_channel_id. ([#7455])
 - pay: The pay plugin now checks whether we have enough spendable capacity before computing a route, returning a clear error message if we don't ([#7418])
 - pay: Payments now emit `channel_hint_updated` notification to share inferred balances and observations across multiple payments. ([#7487])
 - pay: The pay plugin now returns better error codes ([#7418])
 - reckless-rpc plugin: issue commands to reckless over rpc. ([#7506])
 - reckless: accepts json array input for command targets ([#7484])
 - reckless provides json output with option flag -j/--json ([#7484])
 - reckless: added the ability to install rust plugins. ([#7484])
 - JSON-RPC: `listpeers` `features` array string uses "option_anchors" for feature 22/23, following renaming in BOLT 9. ([#7388])
 - plugins: `bookkeeper` now listens for two custom events: `utxo_deposit` and `utxo_spend`. This allows for 3rd party plugins to send onchain coin events to the `bookkeeper`.  See the new plugins/bkpr/README.md for details on how these work! ([#7258])
 - plugins: Add payment_id parameter to bkpr-listaccountevents to filter events. ([#7536])
 - cln-plugin: add multi options for String and i64 ([#7544])
 - pyln-client: Added a notification mechanism for config changes ([#7289])
 - pyln-client: implement setconfig hook for plugins so you can see changes in `dynamic` options. ([#7289])
 - doc: all examples in the documentation are now generated from running the code, so they are current. ([#7457])


### Changed

 - protocol: We now send current peers our changed gossip (even if they set timestamp_filter otherwise), not just on reconnect. ([#7554])
 - protocol: we now always ask the first peer for all its gossip. ([#7512])
 - connectd: I/O optimizations to significantly speed up larger nodes. ([#7365])
 - plugins: the `fetchinvoice` plugin has been combined into the `offers` plugin. ([#7456])
 - close: We no longer attempt to publish a unilateral close that'd fail anyway when we witness a close onchain. ([#7447])
 - pay: Improved logging should facilitate debugging considerably. ([#7418])
 - reckless: option flags are now position independent. ([#7484])
 - plugins: now allows date and time sqlite functions. ([#7467])
 - splice: added outnum of new funding output to splice_signed RPC command ([#7465])
 - lightningd: we wait for bitcoind if it has somehow gone backwards (as long as header height is still ok). ([#7342])
 - wallet: The channel status is printed when loading it from the DB ([#7354])
 - JSON-RPC: `listclosedchannels`, `listpeerchannels`, `openchannel_update`, `openchannel_init`, `fundchannel`, `fundchannel_start` and `multifundchannel`: `channel_type` array `names` now contains "anchors" instead of "anchors_zero_fee_htlc_tx". ([#7388])
 - JSON-RPC: Do not return the contents of invalid parameters in error messages, refer to logs (use 'check' to get full error messages) ([#7420])
 - lightningd: `--list-features-only` now lists "option_anchors" instead of "option_anchors_zero_fee_htlc_tx". ([#7388])
 - updated Bitcoin to v27.1 and Elements to v23.2.1 ([#7436])
 - update libwally to 1.3.0 ([#7480])


### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - JSON-RPC: `listpeers` `features` array string "option_anchors_zero_fee_htlc_tx": use "option_anchors" (spec renamed it). ([#7388])
 - config: the --experimental-onion-messages option is ignored (on by default). ([#7455])
 - config: the --experimental-anchors option is ignored (on by default since v24.02). ([#7454])
 - pyln-client: `category`, `description` and `long_description` for RPC commands are deprecated now. ([#7520])


### Removed

 - JSON-RPC: `sendonionmessage` (was experimental only, use `injectonionmessage`) ([#7461])
 - JSON-RPC: `autocleaninvoice` command (deprecated v22.11, EOL v24.02) ([#7298])
 - plugins: `estimatefees` returning feerates by name (e.g. "opening"); deprecated in v23.05. ([#7380])


### Fixed

 - protocol: we can now open unannounced channels with LND nodes again. ([#7564])
 - plugins: `sql` crash on querying `listpeerchannels` during channel establishment. ([#7578])
 - config: whitespace at the end of (most) options is now ignored, not complained about. ([#7251])
 - connectd: now should use far less CPU on large nodes. ([#7365])
 - lightningd: occasionally we could miss transaction outputs (not telling gossipd, or even onchaind) ([#7567])
 - notifications: we now send a `coin_movement` notification for splice confirmations of channel funding outpoint spends. ([#7533])

### EXPERIMENTAL

 - JSON-RPC: `offer` removed `@` prefix support from `recurrence_base` (use `recurrence_start_any_period` set to `false`) ([#7380])
 - protocol: pay can now pay to bolt12 invoices if entry to blinded hop is specified as a short_channel_id (rather than node id). ([#7461])
 - plugins: pay can now pay a bolt12 invoice even if we, ourselves, are the head of the blinded path within it. ([#7461])
 - offers: automatically add a blinded path from a peer if we have no public channels, so unannounced nodes can have offers too. ([#7461])
 - offers: we can now self-fetch and self-pay BOLT12 offers and invoices. ([#7461])
 - offers: recurring offers had incompatible changes, won't work against older versions. ([#7476])
 - offers: handle experimental ranges in offers/invoice_requests/invoices. ([#7474])
 - offers: `invoicerequest` will set a blinded path if we're an unannounced node. ([#7476])
 - offers: `sendinvoice` will use a blinded path in an invoice_request, if specified. ([#7476])
 - offers: maintain unknown fields offers/invoice_requests correctly. ([#7474])
 - offers: fixed: onionmessage replies now work even if we need to route to the start of the blinded reply path. ([#7456])
 - offers: fixed: fetchinvoice tries all blinded paths until one is usable, and handles case where we have to route more than one hop to reach the entry point. ([#7456])
 - renepay: prune the network by disabling channels we don't like, eg. very low max_htlc. ([#7403])
 - renepay: fixed: un-reserve routes that have completed or failed ([#7357])
 - renepay: Add a dev parameter representing a constant probability of availability for all channels in the network. ([#7540])
 - renepay: add cli option "exclude" to manually disable channels and nodes. ([#7403])

 - Plugins: `cln-plugin` adds dynamic configs and a callback for changes ([#7293])
 - JSON-RPC: `pay` has a new parameter `partial_msat` to only pay part of an invoice (someone else presumably will pay the rest at the same time!) ([#7145])
 - JSON-RPC: `check` `keysend` now checks with HSM that it will approve it. ([#7111])
 - Plugins: Can now opt in to handle `check` command on their commands, for more thorough checking. ([#7111])
 - JSON-RPC: `check` `setconfig` now checks that the new config setting would be valid. ([#7111])
 - JSON-RPC: `check` `setconfig` on plugin options can now check the config value would be accepted. ([#7111])
 - Plugins: `cln-grpc` adds notifications over the grpc interface. Configurable with config parameter `grpc-msg-buffer-size`. ([#7084])
 - Plugins: Added `wss-proxy`, a WSS Proxy server with `wss-bind-addr` and `wss-certs` configurations. ([#7225])
 - Plugins: `cln-grpc` added GRPC support for remaining methods: `dev-forget-channel`, `emergencyrecover`, `recover`, `recoverchannel`, `funderupdate`, `help`, `invoicerequest`, `listinvoicerequests`, `disableinvoicerequest`, `listconfigs`, `makesecret`, `multiwithdraw`, `showrunes`, `createrune`, `blacklistrune`, `checkrune` ([#7317]), addpsbtoutput ([#7108]), `openchannel_init`, `openchannel_abort`, `openchannel_bump`, `openchannel_signed`, `openchannel_update` ([#7230]), `delpay` ([#7232]), `delforward` ([#7260]), `autoclean-once`, `autoclean-status` ([#7238]), `fundchannel_start`, `fundchannel_complete`, `fundchannel_cancel` ([#7231]), `bkpr-channelsapy`, `bkpr-dumpincomecsv`, `bkpr-inspect`, `bkpr-listaccountevents`, `bkpr-listbalances` ([#7256]), `disableoffer` ([#7233]), `parsefeerate`, `plugin`, `renepay`, `renepaystatus`, `sendinvoice` ([#7272]), `reserveinputs`, `unreserveinputs`, `splice_init`, `splice_signed`, `splice_update` ([#7273]), `sendonionmessage`, `setconfig`, `setpsbtversion`, `upgradewallet` ([#7274]).
 - Plugins: `cln_plugin` adds rust plugin support for wildcard `*` subscriptions.  ([#7106])
 - Config: Add `bitcoin-rpcclienttimeout` config parameter. ([#7095])
 - Plugins: new `log` notification when a log line is emitted. ([#6990])
 - Config: new log level `trace` where we moved the very noisiest `debug` logs. ([#7280])
 - Plugins: `clnrest` added a new configuration `clnrest-swagger-root` to change the default Swagger UI path from `/` to custom url. ([#7256])


### Changed

 - Documentation: great documentation rewrite, all reference pages now generated from the fully-tested JSON schemas and include examples. ([#6995])
 - Protocol: `--ignore-fee-limits` / `setchannel ignorefeelimits` no longer applies to mutual close. ([#7252])
 - Plugins: `bcli`: Add a path that tries to fetch blocks ([#7240])
 - Plugins: libplugin now shows plugin option default values (where they're non-trivial) ([#7306])
 - Runes: named parameters (e.g. `pnameamountmsat`) no longer need to remove underscores (i.e. `pnameamount_msat` now works as expected). ([#7124])
 - lightningd: we now try to increase the number of file descriptors, if it's less than twice the number of channels at startup (and log if we cannot!). ([#7237])
 - connectd: prioritize peers with channels (and log!) if we run low on file descriptors. ([#7237])
 - lightningd: Processing blocks should now be faster ([#7101])
 - Plugins: `cln-grpc` adds routes to `decode` and `decodepay` results ([#7317])
 - hsmd: the hsmd now supports `HSM_VERSION 6` ([#7178])
 - hsmd: `HSM_VERSION 6`: `get_per_commitment_point` does not imply index - 2 is revoked, makes it safe to call on any index. ([#7178])
 - Documentation: Merged `example_json_request` and `example_json_response` in a single `json_examples` array to maintain the request and its corresponding response together. ([#7181])
 - JSON-RPC: `stop` and `recover` now return a JSON object (not a raw string!) like every other command does. ([#6995])
 - Plugins: `pay` payments are more robust for nodes that are currently syncing. ([#7190])

 - JSON-RPC: `delexpiredinvoice` (deprecated v22.11, EOL v24.02) ([#7094])
 - JSON-RPC feerates by internal names ("opening", "mutual_close", "delayed_to_us", "htlc_resolution", "penalty", "min_acceptable", "max_acceptable") (deprecated v23.05, EOL v24.02). ([#7094])
 - Plugins: `invoice_payment` and `htlc_accepted` hook `failure_code` response (deprecated v22.08 and v0.8, EOL v23.02) ([#7094])

 - Plugins: `clnrest` now correctly self-disables if Python not present at all. ([#7211])
 - lightningd: slow memory leak when using plugin hooks fixed (introduced in v23.11) ([#7192])
 - Plugins: `recovery` is less noisy. ([#7116])

 - Gossmap: Avoid adding redundant channel announcements to the gossip_store. ([#7330])
 - Protocol: forward legacy non-TLV onions which we removed in 22.11 and spec itself in Feb 2022.  Still sent by LND nodes who haven't seen our node_announcement. ([#7352])

 - gossipd: Fixed a crash when processing pending node announcements. ([#7368])


### EXPERIMENTAL

 - offers: We will now reply to invoice_request messages even if reply path requires us to make an outgoing connection (LDK does this) ([#7304])
 - offers: we now understand blinded paths which use a short-channel-id(+direction) as entry point. ([#7212])
 - offers: Fix blinded paths in invoices - use node_id and set final node's CLTV delta. ([#7311])

 - JSON-RPC: `feerates` `unilateral_close_satoshis` now assumes anchor channels if enabled (currently experimental). ([#6334])


### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - JSON-RPC: `commando-rune`, `commando-listrunes` and `commando-blacklist` (use `createrune`, `showrunes` and `blacklistrune` ([#6403])
 - JSON-RPC: `connect`, `disconnect` and `block_added` notification fields outside the same-named object (use .connect/.disconnect/.block_added sub-objects) ([#6388])
 - `pay` has *undeprecated* paying a description-hash invoice without providing the description. ([#6337])
 - JSON-RPC: `listconfigs` direct fields, use `configs` sub-object and `set`, `value_bool`, `value_str`, `value_int`, or `value_msat` fields. ([#6243])
 - Config: boolean plugin options set to `1` or `0` (use `true` and `false` like non-plugin options). ([#6243])
 - Config: `accept-htlc-tlv-types` (use `accept-htlc-tlv-type` multiple times) ([#6243])
 - Config: `experimental-websocket-port`: use `--bind-addr=ws::<portnum>`. ([#6173])
 - Config: bind-addr=xxx.onion and addr=xxx.onion, use announce-addr=xxx.onion (which was always equivalent). ([#6173])
 - Config: addr=/socketpath, use listen=/socketpath (which was always equivalent). ([#6173])
 - Config: `announce-addr-dns`; use `--bind-addr=dns:ADDR` for finer control. ([#6173])


### Removed

 - Plugins: `commando` no longer allows datastore ['commando', 'secret'] to override master secret (re-issue runes if you were using that!). ([#6431])
 - Plugins: pay: `pay` no longer splits based on common size, as it was causing issues in various scenarios. ([#6400])
 - Build: Support for python v<=3.7 & Ubuntu bionic ([#6414])


### Fixed

 - Protocol: Fix incompatibility with LND which prevented us opening private channels ([#6304])
 - Protocol: We no longer gossip about recently-closed channels (Eclair gets upset with this). ([#6413])
 - Protocol: We will close incoming HTLCs early if the outgoing HTLC is stuck onchain long enough, to avoid cascating failure. ([#6378])
 - JSON-RPC: `close` returns a `tx` field with witness data populated (i.e. signed). ([#6468])
 - Protocol: When we send our own gossip when a peer connects, send our node_announcement too (regression in v23.05) ([#6412])
 - Protocol: `dualopend`: Fix behavior for tx-aborts. No longer hangs, appropriately continues re-init of RBF requests without reconnection msg exchange. ([#6461])
 - Protocol: Node announcements are refreshed more reliably. ([#6454])
 - Build: Small fix for Mac OS building ([#6253])
 - msggen: `listpays` now includes the missing `amount_msat` and `amount_sent_msat` fields ([#6441])
 - Protocol: Adding a >0 version witness program to a fallback address now is *just* the witness program, as per bolt11 spec ([#6435])
 - JSON-RPC: `sendonion` and `sendpay` will now consider amounts involved when using picking one channel for a peer ([#6428])
 - Plugins: pay: We now track spendable amounts when routing on both the local alias as well as the short channel ID ([#6428])
 - Plugins: pay: will still use an invoice routehint if path to it doesn't take 1-msat payments. ([#6579])
 - Config: `log-level` filters now apply correctly to messages from `connectd`. ([#6406])
 - Lightnind: don't infinite loop on 32 bit platforms if only invoices are expiring after 2038. ([#6361])
 - JSON-RPC: `pay` and `decodepay` with description now correctly handle JSON escapes (e.g " inside description) ([#6337])
 - Plugins: `commando` runes can now compare integer parameters using '<' and '>' as expected. ([#6295])
 - Plugins: reloaded plugins get passed any vars from configuration files. ([#6243])
 - JSON-RPC: `listconfigs` `rpc-file-mode` no longer has gratuitous quotes (e.g. "0600" not "\"0600\""). ([#6243])
 - JSON-RPC: `listconfigs` `htlc-minimum-msat`, `htlc-maximum-msat` and `max-dust-htlc-exposure-msat` fields are now numbers, not strings. ([#6243])
 - Protocol: We may propose mutual close transaction which has a slightly higher fee than the final commitment tx (depending on the outputs, e.g. two taproot outputs). ([#6547])
 - Protocol: We now close connection with a peer if adding an HTLC times out (which may be a TCP connectivity issue). ([#6520])
 - Plugins: we clean up properly if a plugin fails to start, and we don't kill all processes if it's from `plugin startdir`. ([#6570])
 - lightning-cli: properly returns help without argument ([#6568])


### EXPERIMENTAL

 - Build: all experimental features are now runtime-enabled; no more `./configure --enable-experimental-features` ([#6209])
 - Protocol: `experimental-splicing` to enable splicing & resizing of active channels. ([#6253])
 - protocol: `experimental-anchors` to support zero-fee-htlc anchors (`option_anchors_zero_fee_htlc_tx`). ([#6334])
 - Protocol: Removed support for advertizing websocket addresses in gossip. ([#6173])
 - Crash: Fixed crash in dual-funding. ([#6273])
 - Config: `experimental-upgrade-protocol` enables simple channel upgrades. ([#6209])
 - Config: `experimental-quiesce` enables quiescence, for testing. ([#6209])

## [23.05] - 2023-05-10: "Austin Texas Agreement(ATXA)"

This release named by @instagibbs

NOTE 1: This release contains breaking changes of the Great Msat migration started in v0.12.0, so "msat" fields are no longer strings with "msat" appended, but simply integers.

### Added

 - Protocol: blinded payments are now supported by default (not just with `--experimental-onion-messages`) ([#6138])
 - Protocol: we now always double-check bitcoin addresses are correct (no memory errors!) before issuing them. ([#5708])

 - Protocol: spending unilateral close transactions now use dynamic fees based on deadlines (and RBF), instead of fixed fees. ([#6120])
 - Protocol: Allow slight overpaying, even with MPP, as spec now recommends. ([#6138])
 - `msggen`: The generated interfaces `cln-rpc` anc `cln-grpc` can now work with a range of versions rather than having to match the CLN version ([#6142])
 - `grpc`: The mTLS private keys are no longer group-readable ([#6075])


### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - JSON-RPC: `close`, `fundchannel`, `fundpsbt`, `multifundchannel`, `multiwithdraw`, `txprepare`, `upgradewallet`, `withdraw` `feerate` (`feerange` for `close`) expressed as, "delayed_to_us", "htlc_resolution", "max_acceptable" or "min_acceptable".  Use explicit block counts or *slow*/*normal*/*urgent*/*minimum*. ([#6120])

## [23.02.2] - 2023-03-14: "CBDC Backing Layer III"


### Added

 - JSON-RPC: Restore `pay` for a bolt11 which uses a `description_hash`, without setting `description` (still deprecated, but the world is not ready) [

[#6092]: https://github.com/ElementsProject/lightning/pull/6092


## [23.02.1] - 2023-03-10: "CBDC Backing Layer II"

This release named by @whitslack

### Added

## [23.02] - 2023-03-01: "CBDC Backing Layer"

This release named by @whitslack

NOTE 1: This release contains breaking protocol changes to dual-funding and
        offers, making them incompatible with previous releases.
NOTE 2: Periodic pruning of channels now keeps track of them as 'zombies.' This
        behavior is in line with the lightning specification but results in
        fewer nodes and channels listed by `listnodes`/`listpeers`. These
        channels will resume as soon as the missing side broadcasts a recent
        channel update.


### Added

 - Plugins: `sql` plugin command to perform server-side complex queries. ([#5679])
 - JSON-RPC: `preapprovekeysend`: New command to preapprove payment details with an HSM. ([#5821])
 - JSON-RPC: `preapproveinvoice`: New command to preapprove a BOLT11 invoice with an HSM. ([#5821])
 - JSON-RPC: `listpeerchannels`: New command to return information on direct channels with our peers. ([#5825])
 - JSON-RPC: `signinvoice`: New command to sign a BOLT11 invoice. ([#5697])
 - JSON-RPC: `upgradewallet`: New command to sweep all p2sh-wrapped outputs to a native segwit output. ([#5670])
 - JSON-RPC: `fundpsbt` option `nonwrapped` filters out p2sh wrapped inputs. ([#5670])
 - JSON-RPC: `listpeers` output now has `num_channels` as `channels` is deprecated (see `listpeerchannels`). ([#5968])
 - JSON-RPC: `listchannels` added a `direction` field (0 or 1) as per gossip specification. ([#5679])
 - cli: `--commando=peerid:rune` (or `-c peerid:rune`) as convenient shortcut for running commando commands. ([#5866])
 - Plugins: `commando` now supports `filter` as a parameter (for send and receive). ([#5866])
 - Config: Added config option `announce-addr-discovered-port` to set custom port for IP discovery. ([#5842])
 - Config: Added config switch `announce-addr-discovered`: on/off/auto ([#5841])
 - doc: we now annotate what versions JSON field additions and deprecations happenened. ([#5867])
 - SECURITY.md: Where to send sensitive bug reports, and dev GPG fingerprints. ([#5960])


### Changed

 - JSON-RPC: `sendcustommsg` can now be called by a plugin from within the `peer_connected` hook. ([#5361])
 - JSON-RPC: `getinfo` `address` array is always present (though may be empty.) ([#5904])

### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - Config: The --disable-ip-discovery config switch: use `announce-addr-discovered`. ([#5841])
 - JSON-RPC: `newaddr`: `addresstype` `p2sh-segwit` (use default, or `bech32`.) ([#5751])
 - JSON-RPC: `listpeers` `channels` array: use `listpeerchannels`. ([#5825])
 - plugins: `commando` JSON commands without an `id` (see doc/lightningd-rpc.7.md for how to construct a good id field). ([#5866])


### Removed

 - JSON-RPC: `sendpay` `route` argument `style` "legacy" (deprecated v0.11.0) ([#5747])
 - JSON-RPC: `close` `destination` no longer allows p2pkh or p2sh addresses. (deprecated v0.11.0) ([#5747])
 - JSON-RPC: `fundpsbt`/`utxopsbt` `reserve` must be a number, not bool. (deprecated v0.11.0) ([#5747])
 - JSON-RPC: `invoice` `expiry` no longer allowed to be a string with suffix, use an integer number of seconds. (deprecated v0.11.0) ([#5747])
 - JSON-RPC: `pay` for a bolt11 which uses a `description_hash`, without setting `description`. (deprecated v0.11.0) ([#5747])


### Fixed

 - Plugins: `pay` uses the correct local channel for payments when there are multiple available (not just always the first!) ([#5947])
 - Pruned channels are more reliably restored. ([#5839])
 - `delpay`: Actually delete the specified payment (mainly found by `autoclean`). ([#6043])

 - gossmap: Fixed `FATAL SIGNAL 11` on gossmap node announcement parsing. ([#6005])
 - channeld no longer retains dead HTLCs in memory. ([#5882])
 - database: Correctly identity official release versions for database upgrade. ([#5880])
 - Plugins: `commando` now responds to remote JSON calls with the correct JSON `id` field. ([#5866])
 - JSON-RPC: `datastore` handles escapes in `string` parameter correctly. ([#5994])
 - JSON-RPC: `sendpay` now can send to a short-channel-id alias for the first hop. ([#5846])
 - topology: Fixed memleak in `listchannels` ([#5865])


### EXPERIMENTAL

 - Protocol: Peer Storage: Distribute your encrypted backup to your peers, which can be retrieved to recover funds upon complete dataloss. ([#5361])
 - Protocol: `offers` breaking blinded payments change (total_amount_sat required, update_add_tlvs fix, Eclair compat.) ([#5892])

## [22.11.1] - 2022-12-09: "Alameda Yield Generator II"

### Added

 - JSON-RPC: reverts requirement for "jsonrpc" "2.0" inside requests (still deprecated though, just for a while longer!) ([#5783])

### Changed

 - config: `announce-addr-dns` needs to be set to *true* to put DNS names into node announcements, otherwise they are suppressed.

### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - config: `announce-addr-dns` (currently defaults to `false`).  This will default to `true` once enough of the network has upgraded to understand DNS entries. ([#5796])

### Fixed

 - Build: arm32 compiler error in fetchinvoice, due to bad types on 32-bit platforms. ([#5785])
 - JSON-RPC: `autoclean-once` response `uncleaned` count is now correct. ([#5775])
 - Plugin: `autoclean` could misperform or get killed due to lightningd's invalid handling of JSON batching. ([#5775])
 - reckless verbosity properly applied. ([#5781])
 - wireaddr: #5657 allow '_' underscore in hostname part of DNS FQDN ([#5789])

 - JSON-RPC: `delpay` takes optional `groupid` and `partid` parameters to specify exactly what payment to delete. ([#5594])
 - JSON-RPC: `fundchannel`, `multifundchannel` and `fundchannel_start` now accept a `reserve` parameter to indicate the absolute reserve to impose on the peer. ([#5315])
 - Plugins: `keysend` will now attach the longest valid text field in the onion to the invoice (so you can have Sphinx.chat users spam you!) ([#5619])
 - JSON-RPC: `keysend` now has `extratlvs` option in non-EXPERIMENTAL builds. ([#5619])
 - JSON-RPC: `listforwards` now shows `in_htlc_id` and `out_htlc_id` ([#5594])

 - JSON-RPC: `delexpiredinvoice`: use `autoclean-once`. ([#5594])
 - JSON-RPC: `commando-rune` restrictions is always an array, each element an array of alternatives.  Replaces a string with `|`-separators, so no escaping necessary except for `\\`. ([#5539])
 - JSON-RPC: `channel_opened` notification `funding_locked` flag (use `channel_ready`: BOLTs namechange). ([#5490])

## [0.12.0] - 2022-08-23: Web-8 init

This release named by @adi2011.

Developers please note the Great Msat Migration has begun:
1. All JSON amount field names now end in "_msat" (others are deprecated)
2. Their values are strings ending in "msat", but will soon be normal integers.
3. You should accept both: set `allow-deprecated-apis=false` to test!

### Added

 - *NEW*: `commando` a new builtin plugin to send/recv peer commands over the lightning network, using runes. ([#5370])
 - *NEW*: New built-in plugin `bookkeeper` w/ commands `bkpr-listaccountevents`, `bkpr-listbalances`, `bkpr-listincome`, `bkpr-channelsapy`, `bkpr-dumpincomecsv`, `bkpr-inspect` ([#5071])
 - *NEW*: Emergency channel backup ("static backup") which allows us to seek fund recovery from honest peers in case of complete data loss ([#5422])

 - JSON-RPC: `listpeers` new fields for `funding` (`remote_funds_msat`, `local_funds_msat`, `fee_paid_msat`, `fee_rcvd_msat`). ([#5477])
 - JSON-RPC: `listpeers` add optional `remote_addr` ([#5244])
 - JSON-RPC: `listforwards` now shows `out_channel` in more cases: even if it couldn't actually send to it. ([#5330])

 - Protocol: private channels will only route using short-channel-ids if channel opened with option_scid_alias-supporting peer. ([#5501])
 - Protocol: invoice routehints will use fake short-channel-ids for private channels if channel opened with option_scid_alias-supporting peer. ([#5501])
 - Protocol: we now advertize the `option_channel_type` feature (which we actually supported since v0.10.2) ([#5455])
 - Plugins: `channel_state_changed` now triggers for a v1 channel's initial "CHANNELD_AWAITING_LOCKIN" state transition (from prior state "unknown") ([#5381])
 - Plugins: `htlc_accepted_hook` `amount_msat` field. ([#5306])
 - Plugins: `htlc_accepted` now exposes the `short_channel_id` for the channel from which that HTLC is coming from and the low-level per-channel HTLC `id`, which are necessary for bridging two different Lightning Networks when MPP is involved. ([#5303])
 - Plugins: The `openchannel` hook may return a `mindepth` indicating how many confirmations are required. ([#5275])
 - msggen: introduce chain of responsibility pattern to make msggen extensible ([#5216])

 - contrib: Added `fund_ln` to the contrib/startup\_regtest.sh ([#5062])
 - build: Added m1 architecture support for macos ([#4988])
 - build: Reproducible builds now include rust binaries such as the `cln-grpc` plugin ([#5421])


### Changed

 - `lightningd`: will refuse to start with the wrong node_id (i.e. hsm_secret changes). ([#5425])
 - `connectd`: prefer IPv6 connections when available. ([#5244])
 - `connectd`: Only use IP discovery as fallback when no addresses would be announced ([#5344])
 - `connectd`: give busy peers more time to respond to pings. ([#5347])
 - `gossipd`: now accepts spam gossip, but squelches it for ([#5239])
 - gossip: gossip\_store updated to version 10. ([#5239])

## [0.11.2] - 2022-06-24: Simon's Carefully Chosen Release Name III

Regressions since 0.10.2 which could not wait for the 0.12 release,
which especially hurt larger nodes.

### Fixed

 - Protocol: treat LND "internal error" as warnings, not force close events (like v0.10) ([#5326])
 - connectd: no longer occasional crashes when peers reconnect. ([#5300])
 - connectd: another crash fix on trying to reconnect to disconnecting peer. ([#5340])
 - topology: Under some circumstances we were considering the limits on the wrong direction for a channel ([#5286])
 - routing: Fixed an issue where we would exclude the entire channel if either direction was disabled, or we hadn't seen an update yet. ([#5286])
 - connectd: large memory usage with many peers fixed. ([#5312])
 - connectd: reduce initial CPU load when connecting to peers. ([#5328])
 - lightnind: fix failed startup "Could not load channels from the database" if old TORv2 addresses were present. ([#5331])

## [0.11.1] - 2022-05-13: Simon's Carefully Chosen Release Name II

Single change which fixed a bug introduced in 0.11.0 which could cause
unwanted unilateral closes (`bad reestablish revocation_number: 0 vs 3`)

### Fixed

 - connectd: make sure we don't keep stale reconnections around. ([#5256])
 - connectd: fix assert which we could trigger. ([#5256])

[#5256]: https://github.com/ElementsProject/lightning/pull/5256

## [0.11.0.1] - 2022-04-04: Simon's Carefully Chosen Release Name

This release would have been named by Simon Vrouwe, had he responded to my emails!

This marks the name change to core-lightning (#CLN).

### Added

 - Protocol: we now support opening multiple channels with the same peer. ([#5078])
 - Protocol: we send/receive IP addresses in `init`, and send updated node_announcement when two peers report the same remote_addr (`disable-ip-discovery` suppresses this announcement). ([#5052])
 - Protocol: we more aggressively send our own gossip, to improve propagation chances. ([#5200])
 - Plugins: `cln-grpc` first class GRPC interface for remotely controlling nodes over mTLS authentication; set `grpc-port` to activate ([#5013])
 - Database: With the `sqlite3://` scheme for `--wallet` option, you can now specify a second file path for real-time database backup by separating it from the main file path with a `:` character. ([#4890])
 - Protocol: `pay` (and decode, etc) supports bolt11 payment_metadata a-la https://github.com/lightning/bolts/pull/912 ([#5086])
 - JSON-RPC: `invoice` has a new parameter `deschashonly` to put hash of description in bolt11. ([#5121])
 - JSON-RPC: `pay` has new parameter `description`, will be required if bolt11 only has a hash. ([#5122])
 - JSON-RPC: `pay` has new parameter `maxfee` for setting absolute fee (instead of using `maxfeepercent` and/or `exemptfee`) ([#5122])
 - JSON-RPC: `listforwards` has new entry `style`, currently "legacy" or "tlv". ([#5146])
 - JSON-RPC: `delinvoice` has a new parameter `desconly` to remove description. ([#5121])
 - JSON-RPC: new `setchannel` command generalizes `setchannelfee`: you can now alter the `htlc_minimum_msat` and `htlc_maximum_msat` your node advertizes. ([#5103])
 - Config: `htlc-minimum-msat` and `htlc-maximum-msat` to set default values to  advertizes for new channels. ([#5136])
 - JSON-RPC: `listpeers` now includes a `pushed_msat` value. For leased channels, is the total lease_fee. ([#5043])
 - JSON-RPC: `getinfo` result now includes `our_features` (bits) for various Bolt #9 contexts ([#5047])
 - Docker build for ARM defaults to `bitcoin`, but can be overridden with the `LIGHTNINGD_NETWORK` envvar. ([#4896])
 - Developer: A new Rust library called `cln-rpc` can be used to interact with the JSON-RPC ([#5010])
 - JSON-RPC: A new `msggen` library allows easy generation of language bindings for the JSON-RPC from the JSON schemas ([#5010])
 - JSON-RPC: `listchannels` now includes the `funding_outnum` ([#5016])
 - JSON-RPC: `coin_movement` to 'external' accounts now include an 'originating_account' field ([#5019])
 - JSON-RPC: Add `exclude` option for `pay` command to manually exclude channels or nodes when finding a route. ([#4906])
 - Database: Speed up loading of pending HTLCs during startup by using a partial index. ([#4925])


### Changed

 - JSON-RPC: `close` by peer id will fail if there is more than one live channel (use `channel_id` or `short_channel_id` as id arg). ([#5078])
 - JSON_RPC: `sendcustommsg` now works with any connected peer, even when shutting down a channel. ([#4985])
 - JSON_RPC: `ping` now works with connected peers, even without a channel. ([#4985])
 - cli: Addition of HSM specific error code in lightning-cli ([#4908])
 - config: If the port is unspecified, the default port is chosen according to used network similarly to Bitcoin Core. ([#4900])
 - Plugins: `shutdown` notification is now send when lightningd is almost completely shutdown, RPC calls then fail with error code -5. ([#4897])
 - Protocol: `signet` addresses and invoices now use `tbs` instead of `tb`. ([#4929])


### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - JSON-RPC: `pay` for a bolt11 which uses a `description_hash`, without setting `description`. ([#5122])
 - JSON-RPC: `invoice` `expiry` no longer allowed to be a string with suffix, use an integer number of seconds. ([#5104])
 - JSON-RPC: `fundpsbt`/`utxopsbt` `reserve` must be a number, not bool (for `true` use 72/don't specify, for `false` use 0).  Numbers have been allowed since v0.10.1. ([#5104])
 - JSON-RPC: `shutdown` no longer allows p2pkh or p2sh addresses. ([#5086])
 - JSON-RPC: `sendpay` `route` argument `style` "legacy" (don't use it at all, we ignore it now and always use "tlv" anyway). ([#5120])
 - JSON-RPC: `setchannelfee` (use `setchannel`). ([#5103])


### Removed

 - JSON-RPC: `legacypay` (`pay` replaced it in 0.9.0). ([#5122])
 - Protocol: support for legacy onion format removed, since everyone supports the new one. ([#5058])
 - Protocol: ... but we still forward legacy HTLC onions for now. ([#5146])
 - Plugins:  The `message` field on the `custommsg` hook (deprecated in v0.10.0) ([#4902])
 - JSON-RPC: `fundchannel_complete` `txid` and `txout` parameters (deprecated in v0.10.0) ([#4902])


### Fixed

 - onchaind: we sometimes failed to close upstream htlcs if more than one HTLC is in flight during unilateral close. ([#5130])
 - JSON-RPC: `listpays` always includes `bolt11` or `bolt12` field. ([#5122])
 - cli: don't ask to confirm the password if the `hsm_secret` is already encrypted. ([#5085])
 - cli: check if the `hsm_secret` password and the confirmation match from the command line ([#5085])
 - JSON-RPC: `connect` notification now called even if we already have a live channel. ([#5078])
 - docker: The docker image is now built with postgresql support ([#5081])

## [0.10.2] - 2021-11-03: Bitcoin Dust Consensus Rule

This release named by @vincenzopalazzo.

### Added

 - config: new option `--max-dust-htlc-exposure-msat`, which limits the total amount of sats to be allowed as dust on a channel ([#4837])
 - With `sqlite3` db backend we now use a 60-second busy timer, to allow backup processes like `litestream` to operate safely. ([#4867])
 - pay: Payment attempts are now grouped by the pay command that initiated them ([#4567])
 - JSON-RPC: `setchannelfee` gives a grace period (`enforcedelay`) before rejecting old-fee payments: default 10 minutes. ([#4806])
 - Support filtering `listpays` by their status. ([#4595])
 - `close` now notifies about the feeranges each side uses. ([#4784])
 - Protocol: We now send and support `channel_type` in channel open (not dual-funding though). ([#4616])
 - Protocol: We now perform quick-close if the peer supports it. ([#4599])
 - JSONRPC: `close` now takes a `feerange` parameter to set min/max fee rates for mutual close. ([#4599])
 - Protocol: Allow sending large HTLCs if peer offers `option_support_large_channel` (> 4294967295msat) ([#4599])
 - pyln-client: routines for direct access to the gossip store as Gossmap ([#4582])
 - Plugins: `shutdown` notification for clean exits. ([#4754])
 - Plugins: Added `channel_id` and `commitnum` to `commitment_revocation` hook ([#4760])
 - JSON-RPC: `datastore`, `deldatastore` and `listdatastore` for plugins to store simple persistent key/value data. ([#4674])


### Changed

 - pay: The route selection will now use the log-propability-based channel selection to increase success rate and reduce time to completion ([#4771])
 - Plugins: `pay` now biases towards larger channels, improving success probability. ([#4771])
 - db: removal of old HTLC information and vacuuming shrinks large lightningd.sqlite3 by a factor of 2-3. ([#4850])
 - JSON-RPC: `ping` now only works if we have a channel with the peer. ([#4804])
 - Protocol: Send regular pings to detect dead connections (particularly for Tor). ([#4804])
 - Build: Python is now required to build, as generated files are no longer checked into the repository. ([#4805])
 - pyln-spec: updated to latest BOLT versions. ([#4763])
 - JSON-RPC: Change order parameters in the `listforwards` command ([#4668])
 - db: We now set a busy timeout to safely allow others to access sqlite3 db (e.g. litestream) ([#4554])
 - connectd: Try non-TOR connections first ([#4731])


### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - Protocol: No longer restrict HTLCs to less than 4294967295msat ([#4599])
 - Change order of the `status` parameter in the `listforwards` rpc command. ([#4668])
 - RPC framework now requires the `"jsonrpc"` property inside the request. ([#4742])
 - Plugins: Renames plugin init `use_proxy_always` to `always_use_proxy` ([#4731])


### Removed



### Fixed

 - peer: Fixed a crash when a connection is lost outside of a DB transaction ([#4894])
 - We now no longer self-limit the number of file descriptors (which limits the number of channels) in sufficiently modern systems, or where we can access `/proc` or `/dev/fd`.  We still self-limit on old systems where we cannot find the list of open files on `/proc` or `/dev/fd`, so if you need > ~4000 channels, upgrade or mount `/proc`. ([#4872])
 - errors: Errors returning a `channel_update` no longer return an outdated one. ([#4876])
 - pay: `listpays` returns payments orderd by their creation date ([#4567])
 - pay: `listpays` no longer groups attempts from multiple attempts to pay an invoice ([#4567])
 - sqlite3: Relaxed the version match requirements to be at least a minimum version and a major version match ([#4852])
 - pay: `pay` would sometimes misreport a final state of `pending` instead of `failed` ([#4803])
 - Plugins: C plugins would could leak memory on every command (esp. seen when hammering topology's `listchannels`). ([#4737])
 - libplugin: Fatal error messages from `plugin_exit()` now logged in lightningd. ([#4754])
 - `openchannel_signed` would fail on PSBT comparison of materially identical PSBTs ([#4752])
 - doc: `listnodes` fields now correctly documented. ([#4750])

[0.10.2]: https://github.com/ElementsProject/lightning/releases/tag/v0.10.2

## [0.10.1] - 2021-08-09: "eltoo: Ethereum Layer Too"

This release named by @nalinbhardwaj.

NOTE ONE: Both the dual-funding and offers protocols have changed, and
are incompatible with older releases (they're both still draft) #reckless

NOTE TWO: `rebalance` and `drain` plugins will need to be redownloaded as
older versions will no longer work -- `payment_secret` is now compulsory.


### Added

 - JSON-RPC: `invoice` now outputs explicit `payment_secret` as its own field. ([#4646])
 - JSON-RPC: `listchannels` can be queried by `destination`. ([#4614])
 - JSON-RPC: `invoice` now gives `warning_private_unused` if unused unannounced channels could have provided sufficient capacity. ([#4585])
 - JSON-RPC: `withdraw`, `close` (and others) now accept taproot (and other future) segwit addresses. ([#4591])
 - JSON-RPC: HTLCs in `listpeers` are now annotated with a status if they are waiting on an `htlc_accepted` hook of a plugin. ([#4580])
 - JSON-RPC: `close` returns `type` "unopened" if it simply discards channel instead of empty object. ([#4501])
 - JSON-RPC: `listfunds` has a new `reserved_to_block` field. ([#4510])
 - JSON-RPC: `createonion` RPC command now accepts an optional `onion_size`. ([#4519])
 - JSON-RPC: new command `parsefeerate` which takes a feerate string and returns the calculated perkw/perkb ([#4639])
 - Protocol: `option_shutdown_anysegwit` allows future segwit versions on shutdown transactions. ([#4556])
 - Protocol: We now send and accept `option_shutdown_anysegwit` so you can close channels to v1+ segwit addresses. ([#4591])
 - Plugins: Plugins may now send custom notifications that other plugins can subscribe to. ([#4496])
 - Plugins: Add `funder` plugin, which allows you to setup a policy for funding v2 channel open requests. Requres --experimental-dual-fund option ([#4489])
 - Plugins: `funder` plugin includes command `funderupdate` which will show current funding configuration and allow you to modify them ([#4489])
 - Plugins: Restart plugin on `rescan` when binary was changed. ([#4609])
 - keysend: `keysend` can now reach non-public nodes by providing the `routehints` argument if they are known. ([#4611])
 - keysend: You can now add extra TLVs to a payment sent via `keysend` ([#4610])
 - config: `force_feerates` option to allow overriding feerate estimates (mainly for regtest). ([#4629])
 - config: New option `log-timestamps` allow disabling of timestamp prefix in logs. ([#4504])
 - hsmtool: allow piped passwords ([#4571])
 - libhsmd: Added python bindings for `libhsmd` ([#4498])
 - libhsmd: Extracted the `hsmd` logic into its own library for other projects to use ([#4497])
 - lightningd: we now try to restart if subdaemons are upgraded underneath us. ([#4471])


### Changed

 - JSON-RPC: `invoice` now allows creation of giant invoices (>= 2^32 msat) ([#4606])
 - JSON-RPC: `invoice` warnings are now better defined, and `warning_mpp_capacity` is no longer included (since `warning_capacity` covers that). ([#4585])
 - JSON-RPC: `getroute` is now implemented in a plugin. ([#4585])
 - JSON-RPC: `sendonion` no longer requires the gratuitous `direction` and `channel` fields in the `firsthop` parameter. ([#4537])
 - JSON-RPC: moved dev-sendcustommsg to sendcustommsg ([#4650])
 - JSON-RPC: `listpays` output is now ordered by the `created_at` timestamp. ([#4518])
 - JSON-RPC: `listsendpays` output is now ordered by `id`. ([#4518])
 - JSON-RPC: `autocleaninvoice` now returns an object, not a raw string. ([#4501])
 - JSON-RPC: `fundpsbt` will not include UTXOs that aren't economic (can't pay for their own fees), unless 'all' ([#4509])
 - JSON-RPC: `close` now always returns notifications on delays. ([#4465])
 - Protocol: All new invoices require a `payment_secret` (i.e. modern TLV format onion) ([#4646])
 - Protocol: Allow out-of-bound fee updates from peers, as long as they're not getting *worse* ([#4681])
 - Protocol: We can no longer connect to peers which don't support `payment_secret`. ([#4646])
 - Protocol: We will now reestablish and negotiate mutual close on channels we've already closed (great if peer has lost their database). ([#4559])
 - Protocol: We now assume nodes support TLV onions (non-legacy) unless we have a `node_announcement` which says they don't. ([#4646])
 - Protocol: Use a more accurate fee for mutual close negotiation. ([#4619])
 - Protocol: channel feerates reduced to bitcoind's "6 block ECONOMICAL" rate. ([#4507])
 - keysend now uses 22 for the final CLTV, making it rust-lightning compatible. ([#4548])
 - Plugins: `fundchannel` and `multifundchannel` will now reserve funding they use for 2 weeks instead of 12 hours. ([#4510])
 - Plugins: we now always send `allow-deprecated-apis` in getmanifest. ([#4465])


### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.
 - lightningd: `enable-autotor-v2-mode` option.  Use v3.  See https://blog.torproject.org/v2-deprecation-timeline. ([#4549])
 - lightningd: v2 Tor addresses.  Use v3.  See https://blog.torproject.org/v2-deprecation-timeline. ([#4549])
 - JSON-RPC: `listtransactions` `outputs` `satoshis` field (use `msat` instead). ([#4594])
 - JSON-RPC: `listfunds` `channels` `funding_allocation_msat` and `funding_msat`: use `funding`. ([#4594])
 - JSON-RPC: `listfunds` `channels` `last_tx_fee`: use `last_tx_fee_msat`. ([#4594])
 - JSON-RPC: `listfunds` `channels` `closer` is now omitted if it does not apply, not JSON `null`. ([#4594])

### Removed

 - JSON-RPC: `newaddr` no longer includes `address` field (deprecated in 0.7.1) ([#4465])

## [0.10.0] - 2021-03-28: Neutralizing Fee Therapy

This release named by @jsarenik.

### Added

 - Protocol: we treat error messages from peer which refer to "all channels" as warnings, not errors. ([#4364])
 - Protocol: we now report the new (draft) warning message. ([#4364])
 - JSON-RPC: `connect` returns `address` it actually connected to ([#4436])
 - JSON-RPC: `connect` returns "direction" ("in": they initiated, or "out": we initiated) ([#4452])
 - JSON-RPC: `txprepare` and `withdraw` now return a `psbt` field. ([#4428])
 - JSON-RPC: `fundchannel_complete` takes a psbt parameter. ([#4428])
 - pay: `pay` will now remove routehints that are unusable due to the entrypoint being unknown or unreachable. ([#4404])
 - Plugins: `peer_connected` hook and `connect` notifications have "direction" field. ([#4452])
 - Plugins: If there is a misconfiguration with important plugins we now abort early with a more descriptive error message. ([#4418])
 - pyln: Plugins that are run from the command line print helpful information on how to configure c-lightning to include them and print metadata about what RPC methods and options are exposed. ([#4419])
 - JSON-RPC: `listpeers` now shows latest feerate and unilateral close fee. ([#4407])
 - JSON-RPC: `listforwards` can now filter by status, in and out channel. ([#4349])
 - JSON-RPC: Add new parameter `excess_as_change` to fundpsbt+utxopsbt ([#4368])
 - JSON-RPC: `addgossip` allows direct injection of network gossip messages. ([#4361])
 - pyln-testing: The RPC client will now pretty-print requests and responses to facilitate log-based debugging. ([#4357])


### Changed

 - Plugins: the `rpc_command` hook is now chainable. ([#4384])
 - JSON-RPC: If bitcoind won't give a fee estimate in regtest, use minimum. ([#4405])
 - Protocol: we use `sync_complete` for gossip range query replies, with detection for older spec nodes. ([#4389])
 - Plugins: `peer_connected` rejections now send a warning, not an error, to the peer. ([#4364])
 - Protocol: we now send warning messages and close the connection, except on unrecoverable errors. ([#4364])
 - JSON-RPC: `sendpay` no longer extracts updates from errors, the caller should do it from the `raw_message`. ([#4361])
 - Plugins: `peer_connected` hook is now chainable ([#4351])
 - Plugins: `custommsg` hook is now chainable ([#4358])


### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - JSON-RPC: `fundchannel_complete` `txid` and `txout` parameters (use `psbt`) ([#4428])
 - Plugins: The `message` field on the `custommsg` hook is deprecated in favor of the `payload` field, which skips the internal prefix. ([#4394])


### Removed

 - `bcli` replacements must allow `allowhighfees` argument (deprecated 0.9.1). ([#4362])
 - `listsendpays` will no longer add `amount_msat` `null` (deprecated 0.9.1). ([#4362])


### Fixed

 - Protocol: overzealous close when peer sent more HTLCs than they'd told us we could send. ([#4432])
 - pay: Report the correct decoding error if bolt11 parsing fails. ([#4404])
 - pay: `pay` will now abort early if the destination is not reachable directly nor via routehints. ([#4404])
 - pay: `pay` was reporting in-flight parts as failed ([#4404])
 - pay: `pay` would crash on corrupt gossip store, which (if version was ever wrong) we'd corrupt again ([#4453])
 - pyln: Fixed an error when calling `listfunds` with an older c-lightning version causing an error about an unknown `spent` parameter ([#4417])
 - Plugins: `dev-sendcustommsg` included the type and length prefix when sending a message. ([#4413])

### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

 - Plugins: `bcli` replacements should note that `sendrawtransaction` now has a second required Boolean argument, `allowhighfees`, which if `true`, means ignore any fee limits and just broadcast the transaction. ([3870](https://github.com/ElementsProject/lightning/pull/3870))
 - JSON-RPC: `listsendpays` will no longer add `null` if we don't know the `amount_msat` for a payment. ([3883](https://github.com/ElementsProject/lightning/pull/3883))
 - Plugins: `getmanifest` without any parameters; plugins should accept any parameters for future use. ([3883](https://github.com/ElementsProject/lightning/pull/3883))

### Removed

 - JSON-RPC: txprepare `destination` `satoshi` argument form removed (deprecated v0.7.3) ([3867](https://github.com/ElementsProject/lightning/pull/3867))

### Fixed

 - Plugins: `pay` `presplit` modifier now supports large payments without exhausting the available HTLCs. ([3986](https://github.com/ElementsProject/lightning/pull/3986))
 - Plugins: `pay` corrects a case where we put the sub-payment value instead of the *total* value in the `total_msat` field of a multi-part payment. ([3914](https://github.com/ElementsProject/lightning/pull/3914))
 - Plugins: `pay` is less aggressive with forgetting routehints. ([3914](https://github.com/ElementsProject/lightning/pull/3914))
 - Plugins: `pay` no longer ignores routehints if the payment exceeds 10,000 satoshi. This is particularly bad if the payee is only reachable via routehints in an invoice. ([3908](https://github.com/ElementsProject/lightning/pull/3908))
 - Plugins: `pay` limits the number of splits if the payee seems to have a low number of channels that can enter it, given the max-concurrent-htlcs limit. ([3936](https://github.com/ElementsProject/lightning/pull/3936))
 - Plugins: `pay` will now make reliable multi-part payments to nodes it doesn't have a node_announcement for. ([4035](https://github.com/ElementsProject/lightning/pull/4035))
 - JSON-RPC: significant speedups for plugins which create large JSON replies (e.g. listpays on large nodes). ([3957](https://github.com/ElementsProject/lightning/pull/3957))
 - doc: Many missing manual pages were completed ([3938](https://github.com/ElementsProject/lightning/pull/3938))
 - Build: Fixed compile error on macos ([4019](https://github.com/ElementsProject/lightning/pull/4019))
 - pyln: Fixed HTLCs hanging indefinitely if the hook function raises an exception. A safe fallback result is now returned instead. ([4031](https://github.com/ElementsProject/lightning/pull/4031))
 - Protocol: We now hang up if peer doesn't respond to init message after 60 seconds. ([4039](https://github.com/ElementsProject/lightning/pull/4039))
 - elementsd: PSBTs include correct witness_utxo struct for elements transactions ([4033](https://github.com/ElementsProject/lightning/pull/4033))
 - cli: fixed crash with `listconfigs` in `-H` mode ([4012](https://github.com/ElementsProject/lightning/pull/4012))
 - Plugins: `bcli` significant speedups for block synchronization ([3985](https://github.com/ElementsProject/lightning/pull/3985))
 - Build: On systems with multiple installed versions of the PostgreSQL client library, C-Lightning might link against the wrong version or fail to find the library entirely. `./configure` now uses `pg_config` to locate the library. ([3995](https://github.com/ElementsProject/lightning/pull/3995))
 - Build: On some operating systems the postgresql library would not get picked up. `./configure` now uses `pg_config` to locate the headers. ([3991](https://github.com/ElementsProject/lightning/pull/3991))
 - libplugin: significant speedups for reading large JSON replies (e.g. calling listsendpays on large nodes, or listchannels / listnodes). ([3957](https://github.com/ElementsProject/lightning/pull/3957))

 - JSON-RPC: `fundchannel_cancel` will now succeed even when executed while a `fundchannel_complete` is ongoing; in that case, it will be considered as cancelling the funding *after* the `fundchannel_complete` succeeds. ([3778](https://github.com/ElementsProject/lightning/pull/3778))
 - JSON-RPC: `listfunds` 'outputs' now includes reserved outputs, designated as 'reserved' = true ([3764](https://github.com/ElementsProject/lightning/pull/3764))

### Changed

:warning: The default network and the default location of the lightning home directory changed. Please make sure that the configuration, key file and database are moved into the network-specific subdirectory.

 - config: Default network (new installs) is now bitcoin, not testnet. ([3268](https://github.com/ElementsProject/lightning/pull/3268))

 - JSON API: The `fundchannel` command now tries to connect to the peer before funding the channel, no need to `connect` before `fundchannel` if an address for the peer is known ([3314](https://github.com/ElementsProject/lightning/pull/3314))
 - JSON API: `htlc_accepted` hook has `type` (currently `legacy` or `tlv`) and other fields directly inside `onion`. ([3167](https://github.com/ElementsProject/lightning/pull/3167))
 - JSON API: `lightning_` prefixes removed from subdaemon names, including in listpeers `owner` field. ([3241](https://github.com/ElementsProject/lightning/pull/3241))

 - options: log-level can now specify different levels for different subsystems. ([3241](https://github.com/ElementsProject/lightning/pull/3241))
 - protocol: The TLV payloads for the onion packets are no longer considered an experimental feature and generally available. ([3260](https://github.com/ElementsProject/lightning/pull/3260))
 - quirks: We'll now reconnect and retry if we get an error on an established channel. This works around lnd sending error messages that may be non-fatal. ([3340](https://github.com/ElementsProject/lightning/pull/3340))

:warning: If you don't have a config file, you now may need to specify the network to `lightning-cli` ([3268](https://github.com/ElementsProject/lightning/pull/3268))

## [0.7.2.1] - 2019-08-19: "Nakamoto's Pre-approval by US Congress"

This release was named by Antoine Poinsot @darosior.

(Technically a .1 release, as it contains last-minute fixes after 0.7.2 was tagged)

### Added

- Plugin: a new boolean field can be added to a plugin manifest, `dynamic`. It allows a plugin to tell if it can be started or stopped "on-the-fly".
- Plugin: a new boolean field is added to the `init`'s `configuration`, `startup`. It allows a plugin to know if it has been started on `lightningd` startup.
- Plugin: new notifications `invoice_payment`, `forward_event` and `channel_opened`.
- Protocol: `--enable-experimental-features` adds gossip query extensions
  aka https://github.com/lightningnetwork/lightning-rfc/pull/557
- contrib: new `bootstrap-node.sh` to connect to random mainnet nodes.
- JSON API: `listfunds` now returns also `funding_output` for `channels`
- Plugin: plugins can now suggest `lightning-cli` default to -H for responses.
- Lightningd: add support for `signet` networks using the `--network=signet` or `--signet` startup option

### Changed

- Build: now requires `python3-mako` to be installed, i.e. `sudo apt-get install python3-mako`
- JSON API: `close` optional arguments have changed: it now defaults to unilateral close after 48 hours.
- Plugin: if the config directory has a `plugins` subdirectory, those are loaded.
- lightningd: check bitcoind version when setup topology and confirm the version not older than v0.15.0.
- Protocol: space out reconnections on startup if we have more than 5 peers.
- JSON API: `listforwards` includes the 'payment_hash' field.
- Plugin: now plugins always run from the `lightning-dir` for easy local storage.

### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for
changes.

- Plugin: using startup-relative paths for `plugin` and `plugin-dir`: they're now relative to `lightning-dir`.
- JSON API: `listforwards` removed dummy (zero) fields for `out_msat`, `fee_msat`, `in_channel` and `out_channel` if unknown (i.e. deleted from db, or `status` is `local-failed`.

### Removed

### Fixed

- Plugin: `pay` no longer crashes on timeout.
- Plugin: `disconnect` notifier now called if remote side disconnects.
- channeld: ignore, and simply try reconnecting if lnd sends "sync error".
- Protocol: we now correctly ignore unknown odd messages.

- Detect when we're still syncing with bitcoin network: don't send or receive
  HTLCs or allow `fundchannel`.
- Rare onchaind error where we don't recover our own unilateral close with multiple same-preimage HTLCs fixed.

- JSON API: `listpeers` has new field `scratch_txid`: the latest tx in channel.
- JSON API: `listpeers` has new array `htlcs`: the current live payments.
- JSON API: `listchannels` has two new fields: `message_flags` and `channel_flags`. This replaces `flags`.
- JSON API: `invoice` now adds route hint to invoices for incoming capacity (RouteBoost), and warns if insufficient capacity.
- JSON API: `listforwards` lists all forwarded payments, their associated channels, and fees.
- JSON API: `getinfo` shows forwarding fees earnt as `msatoshi_fees_collected`.
- Bitcoind: more parallelism in requests, for very slow nodes.
- Testing: fixed logging, cleaner interception of bitcoind, minor fixes.
- Protocol: we set and handle the new `htlc_maximum_msat` channel_update field.

### Changed

- Protocol: `channel_update` sent to disable channel only if we reject an HTLC.
- Protocol: we don't send redundant `node_announcement` on every new channel.
- Config: config file can override `lightning-dir` (makes sense with `--conf`).
- Config: `--conf` option is now relative to current directory, not `lightning-dir`.
- lightning-cli: `help <cmd>` prints basic information even if no man page found.
- JSON API: `getinfo` now reports global statistics about forwarded payments, including total fees earned and amounts routed.

### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for
changes.

- JSON RPC: `listchannels`' `flags` field. This has been split into two fields, see Added.
- JSON RPC: `global_features` and `local_features` fields: use `globalfeatures` and `localfeatures` as per BOLT #1.

### Removed

- JSON API: the optional 'seed' parameter to `getroute` was removed.

### Fixed

- Startup: more coherent complaint if daemon already running.
- Lightningd: correctly save full HTLCs across restarts; fixup old databases.
- JSON RPC: `getinfo` now shows correct Tor port.
- JSON RPC: `ping` now works even after one peer fails to respond.
- JSON RPC: `getroute` `fuzzpercent` and `pay` `maxfeepercent` can now be > 100.
- JSON RPC: `riskfactor` in `pay` and `getroute` no longer always treated as 1.
- JSON-RPC: `listpeers` was always reporting 0 for all stats.
- JSON RPC: `withdraw all` says `Cannot afford transaction` if you have
             absolutely no funds, rather than `Output 0 satoshis would be dust`.
- Protocol: don't send gossip about closed channels.
- Protocol: fix occasional deadlock when both peers flood with gossip.
- Protocol: fix occasional long delay on sending `reply_short_channel_ids_end`.
- Protocol: re-send `node_announcement` when address/alias/color etc change.
- Protocol: multiple HTLCs with the same payment_hash are handled correctly.
- Options: 'autotor' defaults to port 9051 if not specified.

### Security

## [0.6.1] - 2018-09-11: "Principled Opposition To Segwit"

This release was named by ZmnSCPxj.

### Added

- Protocol: gossipd now deliberately delays spamming with `channel_update`.
- Protocol: liveness ping when we commit changes but peer is idle: speeds up
  failures and reduces forced closures.
- Protocol: `option_data_loss_protect` now supported to protect peers
  against being out-of-date.
- JSON API: Added description to invoices and payments (#1740).
- JSON API: `getinfo` has new fields `alias` and `color`.
- JSON API: `listpeers` has new fields `global_features` and `local_features`.
- JSON API: `listnodes` has new field `global_features`.
- JSON API: `ping` command to send a ping to a connected peer.
- JSON API: `feerates` command to retrieve current fee estimates.
- JSON API: `withdraw` and `fundchannel` can be given manual feerate.
- Config: `--conf` option to set config file.
- Documentation: Added CHANGELOG.md
- pylightning: RpcError now has `method` and `payload` fields.
- Sending lightningd a SIGHUP will make it reopen its `log-file`, if any.

### Changed

- Protocol: Fee estimates are now smoothed over time, to avoid sudden jumps.
- Config: You can only announce one address if each type (IPv4, IPv6,
  TORv2, TORv3).
- lightning-cli: the help command for a specific command now runs the
  `man` command.
- HSM: The HSM daemon now maintains the per-peer secrets, rather than
  handing them out.  It's still lax in what it signs though.
- connectd: A new daemon `lightning_connectd` handles connecting
  to/from peers, instead of `gossipd` doing that itself. `lightning_openingd` now
  handles peers immediately, even if they never actually open a channel.
- Test: `python-xdist` is now a dependency for tests.
- Logging: JSON connections no longer spam debug logs.
- Routing: We no longer consider channels that are not usable either because of
  their capacity or their `htlc_minimum_msat` parameter (#1777)
- We now try to connect to all known addresses for a peer, not just
  the one given or the first one announced.
- Crash logs are now placed one-per file like `crash.log.20180822233752`
- We will no longer allow withdrawing funds or funding channels if we
  do not have a fee estimate (eg. bitcoind not synced); use new `feerate` arg.

### Deprecated

### Removed

- JSON API: `listpeers` results no long have `alias` and `color` fields;
  they're in `listnodes` (we used to internally merge the information).
- JSON API: `listpeers` will never have `state` field (it accidentally
  used to exist and set to `GOSSIPING` before we opened a channel).
  `connected` will indicate if we're connected, and the `channels`
  array indicates individual channel states (if any).
- Config: `default-fee-rate` is no longer available; use explicit `feerate`
  option if necessary.
- Removed all Deprecated options from 0.6.

### Fixed

- Protocol: `node_announcement` multiple addresses are correctly ordered and uniquified.
- Protocol: if we can't estimate feerate, be almost infinitely
  tolerant of other side setting fees to avoid unilateral close.
- JSON API: `listnodes`: now displays node aliases and colors even if they
  don't advertise a network address
- JSON API: `fundchannel all`: now restricts to 2^24-1 satoshis rather than failing.
- JSON API: `listnodes`: now correctly prints `addresses` if more than
  one is advertised.
- Config: `bind-addr` of a publicly accessible network address was announced.
- When we reconnect and have to retransmit failing HTLCs, the errors weren't
  encrypted by us.
- `lightningd_config` man page is now installed by `make install`.
- Fixed crash when shutting down during opening a channel (#1737)
- Don't lose track of our own output when applying penalty transaction (#1738)
- Protocol: `channel_update` inside error messages now refers to correct channel.
- Stripping type prefix from `channel_update`s that are nested in an onion reply
  to be compatible with eclair and lnd (#1730).
- Failing tests no longer delete the test directory, to allow easier debugging
  (Issue: #1599)

### Security
