+<h3 id="v25-3-1-operational-changes">Operational changes</h3>
+
+- Updated TTL job replanning to be less sensitive by focusing specifically on detecting when nodes become unavailable rather than reacting to all plan differences. The cluster setting `sql.ttl.replan_flow_threshold` may have been set to `0` to work around the TTL replanner being too sensitive; this fix will alleviate that and any instance that had set `replan_flow_threshold` to `0` can be reset back to the default. [#151483][#151483]
+
+<h3 id="v25-3-1-bug-fixes">Bug fixes</h3>
+
+- 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`. [#150440][#150440]
+- 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. [#150620][#150620]
+- Fixed a bug that could cause some errors returned by attempts to upload backup data to external storage providers to go undetected, potentially causing incomplete backups. [#151080][#151080]
+- 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. [#151136][#151136]
+- 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. [#151160][#151160]
+- Fixed a bug where `debug.zip` files collected from clusters with `disallow_full_table_scans` enabled were missing system table data. [#151247][#151247]
+- Fixed a bug where sequences could lose references to triggers, allowing them to be dropped incorrectly. [#151593][#151593]
+- 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. [#152183][#152183]
+
+<h3 id="v25-3-1-miscellaneous">Miscellaneous</h3>
+
+- Updated Go version to 1.23.11. [#150868][#150868]
