Happy new year! This patch release is very small. The main improvement
is better management of pending attestation aggregation via [PR
16153](https://redirect.github.com/OffchainLabs/prysm/pull/16153).

##### Added

- `primitives.BuilderIndex`: SSZ `uint64` wrapper for builder registry
indices.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16169)

##### Changed

- the /eth/v2/beacon/pool/attestations and
/eth/v1/beacon/pool/sync\_committees now returns a 503 error if the node
is still syncing, the rest api is also working in a similar process to
gRPC broadcasting immediately now.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16152)
- `validateDataColumn`: Remove error logs.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16157)
- Pending aggregates: When multiple aggregated attestations only
differing by the aggregator index are in the pending queue, only process
one of them.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16153)

##### Fixed

- Fix the missing fork version object mapping for Fulu in light client
p2p.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16151)
- Do not process slots and copy states for next epoch proposers after
Fulu.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16168)

[`v7.1.1`](https://redirect.github.com/prysmaticlabs/prysm/blob/HEAD/CHANGELOG.md#v711---2025-12-18)

Release highlights:

- Fixed potential deadlock scenario in data column batch verification
- Improved processing and metrics for cells and proofs

We are aware of [an
issue](https://redirect.github.com/OffchainLabs/prysm/issues/16160)
where Prysm struggles to sync from an out of sync state. We will have
another release before the end of the year to address this issue.

Our postmortem document from the December 4th mainnet issue has been
published on our [documentation
site](https://prysm.offchainlabs.com/docs/misc/mainnet-postmortems/)

##### Added

- Track the dependent root of the latest finalized checkpoint in
forkchoice.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16103)
- Proposal design document to implement graffiti. Currently it is empty
by default and the idea is to have it of the form GE168dPR63af.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/15983)
- Add support for detecting and logging per address reachability via
libp2p AutoNAT v2.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16100)
- Static analyzer that ensures each `httputil.HandleError` call is
followed by a `return` statement.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16134)
- Prometheus histogram
`cells_and_proofs_from_structured_computation_milliseconds` to track
computation time for cells and proofs from structured blobs.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16115)
- Prometheus histogram `get_blobs_v2_latency_milliseconds` to track RPC
latency for `getBlobsV2` calls to the execution layer.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16115)

##### Changed

- Optimise migratetocold by not doing brute force for loop.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16101)
- e2e sync committee evaluator now skips the first slot after startup,
we already skip the fork epoch for checks here, this skip only applies
on startup, due to altair always from 0 and validators need to warm up.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16145)
- Run `ComputeCellsAndProofsFromFlat` in parallel to improve performance
when computing cells and proofs.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16115)
- Run `ComputeCellsAndProofsFromStructured` in parallel to improve
performance when computing cells and proofs.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16115)

##### Removed

- Unnecessary copy is removed from Eth1DataHasEnoughSupport.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16118)

##### Fixed

- Incorrect constructor return type
[#&#8203;16084](https://redirect.github.com/OffchainLabs/prysm/pull/16084).
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16084)
- Fixed possible race when validating two attestations at the same time.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16105)
- Fix missing return after version header check in
SubmitAttesterSlashingsV2.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16126)
- Fix deadlock in data column gossip KZG batch verification when a
caller times out preventing result delivery.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16141)
- Fixed replay state issue in rest api caused by attester and sync
committee duties endpoints.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16136)
- Do not error when committee has been computed correctly but updating
the cache failed.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16142)
- Prevent blocked sends to the KZG batch verifier when the caller
context is already canceled, avoiding useless queueing and potential
hangs.
[\[PR\]](https://redirect.github.com/prysmaticlabs/prysm/pull/16144)
