+
+<h3 id="v25-2-5-general-changes">General changes</h3>
+
+- Kafka v2 changefeed sinks now support
+  a cluster setting that enables detailed error logging for messages
+  exceeding Kafka v2 size limit. [#149829][#149829]
+
+<h3 id="v25-2-5-operational-changes">Operational changes</h3>
+
+- Introduced a cluster setting, `sql.stats.error_on_concurrent_create_stats.enabled`, which modifies how CockroachDB reacts to concurrent auto stats jobs. The default, `true`, maintains the previous behavior. Setting `sql.stats.error_on_concurrent_create_stats.enabled` to `false` will cause the concurrent auto stats job to be skipped with just a log entry and no increased error counters. [#149837][#149837]
+
+<h3 id="v25-2-5-bug-fixes">Bug fixes</h3>
+
+- Fixed an issue where the mvcc_timestamp field was incorrectly returning zero values when used with CDC queries. The timestamp is now emitted correctly. [#147114][#147114]
+- Fixed a bug where database login could fail
+  during LDAP, JWT, or OIDC authentication if the user's external group
+  memberships did not correspond to any existing roles in the
+  database. The login will now succeed, and no roles will be granted or
+  revoked in this scenario. [#149747][#149747]
+- Fixed a bug that would cause a `CALL` statement executed via a portal in the extended wire protocol to result in an error like `unknown portal ""` if the stored procedure contained `COMMIT` or `ROLLBACK` statements. The bug had existed since PL/pgSQL transaction control statements were introduced in v24.1. The fix will be off by default in versions prior to v25.3, and can be toggled on by setting `use_proc_txn_control_extended_protocol_fix = true`. [#149851][#149851]
+- Fixed a slow memory leak that was introduced in v25.1.8, v25.2.1, v25.2.2, and v25.3 betas. The leak would accumulate whenever a node executed a part of the distributed plan (the gateway node of the plan was not affected), and could only be mitigated by restarting the node. [#149919][#149919]
+- Fixed an issue where some SQL metrics were not reported when `server.child_metrics.enabled` was enabled, `server.child_metrics.include_aggregate.enabled` was disabled, and `sql.metrics.application_name.enabled` and `sql.metrics.database_name.enabled` were also disabled. Specifically, metrics with no children now report their aggregate metrics regardless of the `server.child_metrics.include_aggregate.enabled` cluster setting. [#149937][#149937]
+- Fixed a bug that would allow a race condition in foreign key cascades under `READ COMMITTED` and `REPEATABLE READ` isolation levels. [#150295][#150295]
+- Fixed an issue where discarding zone configs on sequences did not actually remove the configuration. [#150359][#150359]
+- Fixed a bug where the entire schema would become inaccessible if a table was referenced as an implicit record type by a user-defined function (UDF) while the table was undergoing an `IMPORT`. [#150439][#150439]
+- Fixed invalid zone configurations that were generated when adding a super region to a 3-region database with a secondary region and region survivability. Previously, this could result in assigning more than the allowed number of replicas. [#150619][#150619]
+- Fixed a bug that could cause some errors returned by attempts to upload backup data to external storage providers to be undetected, potentially causing incomplete backups. [#151082][#151082]
+- Fixed a memory accounting issue in the client certificate cache that caused multiple allocations to be reported for the same certificate. The cache now accurately tracks memory usage and includes a safeguard to prevent it from negatively affecting SQL operations. [#151146][#151146]
+- Previously, CockroachDB could encounter an internal error `trying to add a column of UNKNOWN type at ...` in rare cases when handling `CASE` or `OR` operations. This bug was present since v20.2 and is now fixed. [#151161][#151161]
+- Previously, CockroachDB could hit an error `ERROR: span with results after resume span...` when evaluating some queries with `ORDER BY ... DESC` in an edge case. This bug was present since v22.1 and is now fixed. [#152185][#152185]
+
+<h3 id="v25-2-5-miscellaneous">Miscellaneous</h3>
+
+- Upgrade to Go 1.23.11 [#150988][#150988]
