+<h3 id="v25-2-7-bug-fixes">Bug fixes</h3>
+
+- Fixed a bug where an `INSERT` statement could fail with a type checking error while adding a `BIT(n)` column. [#152964][#152964]
+- Fixed a bug where index creation could fail due to validation errors if the schema change was retried or paused/resumed during the backfill. [#153596][#153596]
+- Fixed a bug introduced in v25.1.0 that would cause a node panic if a `SIGINT` signal was sent during the execution of a `CHECK EXTERNAL CONNECTION` command. [#153601][#153601]
+- Fixed a bug where `ALTER POLICY` was incorrectly dropping dependency tracking for functions, sequences, or types in policy expressions. [#153808][#153808]
+- Fixed a runtime error that could be hit if a new secondary index had a name collision with a primary index. [#154015][#154015]
+- Fixed a bug that caused panics when executing `COPY` into a table with hidden columns and expression indexes. The panic only occurred when the session setting `expect_and_ignore_not_visible_columns_in_copy` was enabled. This bug was introduced with `expect_and_ignore_not_visible_columns_in_copy` in v22.1.0. [#154290][#154290]
+- Disabled the `kv.lock_table.unreplicated_lock_reliability.split.enabled` feature, which could lead to a node crash. [#155418][#155418]
+- Fixed a bug where the presence of duplicate temporary tables in a backup caused the restore to fail with an error containing the text `restoring table desc and namespace entries: table already exists`. [#154398][#154398]
