+- Fixed a bug where AVRO file imports of data with JSON or binary records could hang indefinitely when encountering stream errors from cloud storage (such as `HTTP/2` `CANCEL` errors). Import jobs will now properly fail with an error instead of hanging. [#161438][#161438]
+- Fixed a bug that, in rare cases, could cause a node to crash when using a changefeed with the `end_time` option. [#161678][#161678]
+- Fixed a bug that could cause changefeeds using Kafka v1 sinks to hang when the changefeed was cancelled. [#162117][#162117]
+- Fixed a bug where generating a debug zip could trigger an out-of-memory (OOM) condition on a node if malformed log entries were present in logs using `json` or `json-compact` formatting. This bug was introduced in v24.1. [#163360][#163360]
+
+<h3 id="v24-3-29-miscellaneous">Miscellaneous</h3>

+- Fixed a bug where import rollback could incorrectly revert data in a table that was already online. This could only occur if an import job was cancelled or failed after the import had already succeeded and the table was made available for use. [#159900][#159900]

+Release Date: March 9, 2026
+
+{% include releases/new-release-downloads-docker-image.md release=include.release %}
+
+<h3 id="v26-1-1-general-changes">General changes</h3>
+
+- Added support for the `partition_alg` changefeed option to specify a Kafka partitioning algorithm. Supported values are `fnv-1a` (default) and `murmur2`. For example: `CREATE CHANGEFEED ... INTO 'kafka://...' WITH partition_alg='murmur2';`. This option is only valid for Kafka v2 sinks and is controlled by the cluster setting `changefeed.partition_alg.enabled`. Once a changefeed is created with a specific algorithm, it continues to use that algorithm even if the cluster setting is later disabled, unless the changefeed is altered to use a different `partition_alg` value. [#161532][#161532]
+
+<h3 id="v26-1-1-sql-language-changes">SQL language changes</h3>
+
+- The `information_schema.crdb_datums_to_bytes` built-in function is now documented. [#161196][#161196]
+
+<h3 id="v26-1-1-bug-fixes">Bug fixes</h3>
+
+- Fixed a bug where AVRO file imports of data with JSON or binary records could hang indefinitely when encountering stream errors from cloud storage (such as `HTTP/2` `CANCEL` errors). Import jobs will now properly fail with an error instead of hanging. [#161446][#161446]
+- Fixed a bug which prevented successfully injecting hints using `information_schema.crdb_rewrite_inline_hints` for `INSERT`, `UPSERT`, `UPDATE`, and `DELETE` statements. This bug was present since hint injection was first introduced in v26.1.0. [#161970][#161970]
+- Fixed a bug introduced in v26.1.0-beta.1 in which row-level TTL jobs could encounter GC threshold errors if each node had a large number of spans to process. [#161990][#161990]
+- Fixed a bug where multi-statement explicit transactions that use `SAVEPOINT` to recover from certain errors (like duplicate key value violations) could lose writes performed before the savepoint was created in rare cases when buffered writes were enabled. Buffered writes are a public preview feature that is off by default. This bug was introduced in v25.2. [#162031][#162031]
+- Fixed a bug that could cause changefeeds using Kafka v1 sinks to hang when the changefeed was cancelled. [#162121][#162121]
+- Fixed a bug where queries using a generic plan with a lookup join on an index containing identity computed columns would fail with the error "cannot map variable %d to an indexed var". [#162140][#162140]
+- Fixed an internal error "could not find format code for column N" that occurred when executing `EXPLAIN ANALYZE EXECUTE` statements via JDBC or other clients using the PostgreSQL binary protocol. [#162284][#162284]
+- Fixed a bug where CockroachDB would encounter an internal error when evaluating builtin functions with `'{}'` as an argument without explicit type casts (e.g., `SELECT cardinality('{}');`). A regular error is now returned instead, matching PostgreSQL behavior. [#162358][#162358]
+- Fixed a bug in which PL/pgSQL UDFs with many IF statements would cause a timeout and/or OOM when executed from a prepared statement. This bug was introduced in versions v23.2.22, v24.1.15, v24.3.9, v25.1.2, and v25.2.0. [#162560][#162560]
