v.25.5Bug Fix (user-visible misbehavior in an official stable release)

Fixed several types of SELECT queries

Official CH changelog text
Fixed several types of SELECT queries that read from tables with MongoDB engine or mongodb table function: queries with implicit conversion of const value in WHERE clause (e.g. WHERE datetime = '2025-03-10 00:00:00') ; queries with LIMIT and GROUP BY. Previously, they could return the wrong result. #78777 (Anton Popov).
