- Fixed tests - Optimized new code - Fixed some unlikely core dumps - Better bug fixes for: - #14397 - OPTIMIZE TABLE with an open HANDLER causes a crash - #14850 (ERROR 1062 when a quering a view using a Group By on a column that can be null mysql-test/r/create.result: Update results after removing wrong warnings for CREATE ...
