Changes in release 3.22.26
--------------------------
* Fixed core dump with empty `BLOB/TEXT' column to `REVERSE()'.
* Extended `/*! */' with version numbers.
* Changed `SUBSTRING(text FROM pos)' to conform to ANSI SQL. (Before
this construct returned the rightmost 'pos' characters).
* Fixed problem with `LOCK TABLES' combined with `DELETE FROM table'
* Fixed problem that INSERT ... SELECT didn't use SQL_BIG_TABLES.
* `SET SQL_LOW_PRIORITY_UPDATES=#' didn't work.
* Password wasn't updated correctly if privileges didn't change on:
`GRANT ... IDENTIFIED BY'
* Fixed range optimizer bug in `SELECT * FROM table_name WHERE
key_part1 >= const AND (key_part2 = const OR key_part2 = const)'
* Fixed bug in compression key handling in ISAM.
