+* #6908: Fix `time_bucket_gapfill()` with timezone behaviour around daylight savings time (DST) switches.
+* #6911: Fix dropped chunk metadata removal in the update script.
+* #6940: Fix `pg_upgrade` failure by removing `regprocedure` from the catalog table.
+* #6957: Fix then `segfault` in UNION queries that contain ordering on compressed chunks.
