Changes in release 3.21.30
--------------------------

   * `mysql' now returns an exit code > 0 if the query returned an
     error.

   * Saving of command line history to file in `mysql' client.  By
     Tommy Larsen <tommy@mix.hive.no>.

   * Fixed problem with empty lines that were ignored in `mysql.cc'.

   * Save the pid of the signal handler thread in the pid file instead
     of the pid of the main thread.

   * Added patch by <tommy@valley.ne.jp> to support Japanese characters
     SJIS and UJIS.

   * Changed `safe_mysqld' to redirect startup messages to
     `'hostname'.err' instead of `'hostname'.log' to reclaim file space
     on `mysqladmin refresh'.

   * `ENUM' always had the first entry as default value.

   * `ALTER TABLE' wrote two entries to the update log.

   * `sql_acc()' now closes the `mysql' grant tables after a reload to
     save table space and memory.

   * Changed `LOAD DATA' to use less memory with tables and `BLOB'
     columns.

   * Sorting on a function which made a division / 0 produced a wrong
     set in some cases.

   * Fixed `SELECT' problem with `LEFT()' when using the czech character
     set.

   * Fixed problem in `isamchk'; it couldn't repair a packed table in a
     very unusual case.

   * `SELECT' statements with `&' or `|' (bit functions) failed on
     columns with `NULL' values.

   * When comparing a field = field, where one of the fields was a part
     key, only the length of the part key was compared.
