- Backported in #65446: Use correct memory alignment for Distinct combinator. Previously, crash could happen because of invalid memory allocation when the combinator was used. #65379 (Antonio Andelic).

- Backported in #65615: Fix aggregate function name rewriting in the new analyzer. #65110 (Dmitry Novik).

- Backported in #65667: Disable
non-intersecting-parts
optimization for queries withFINAL
in case ofread-in-order
