+
+<h3 id="v25-4-2-sql-language-changes">SQL language changes</h3>
+
+- Fixed two cases where creation of a routine
+  resolves unnecessary column dependencies, which can prevent drop of the
+  column without first dropping the routine. Here, the unnecessary
+  dependencies are due to references within CHECK constraints, including
+  those for RLS policies and hash-sharded indexes, as well as those in
+  partial index predicates. The fix is gated behind the session setting
+  `use_improved_routine_deps_triggers_and_computed_cols`, which is off by
+  default before 26.1. [#159469][#159469]
+
+<h3 id="v25-4-2-bug-fixes">Bug fixes</h3>
+
+- Fixed a bug that could cause prepared statements to fail with the error
+  message "non-const expression" when they contained filters with stable
+  functions. This bug has been present since v25.4.0. [#159209][#159209]
+- Fixed a bug that allowed a column to be dropped from
+  its table despite being referenced by a routine. The bug could happen when the
+  column was only referenced as a target column in the SET clause of an UPDATE
+  statement within the routine. This fix only applies to newly-created routines.
+  In versions prior to v26.1, the fix must be enabled by setting the session
+  variable `prevent_update_set_column_drop`. [#159469][#159469]
+- Fixed a bug that caused routines to prevent
+  dropping more columns than necessary, most notably columns referenced
+  by computed column expressions. The fix is gated behind the session
+  setting `use_improved_routine_deps_triggers_and_computed_cols`, which
+  is off by default prior to v26.1. [#159469][#159469]
