Changes in release 3.21.14a
---------------------------

   * Ported to SCO Openserver 5.0.4  with FSU Pthreads.

   * HP-UX 10.20 should work.

   * Added new function `DATE_FORMAT()'.

   * Added `NOT IN'.

   * Added automatic removal of 'ODBC function conversions': `{fn now()
     }'

   * Handle ODBC 2.50.3 option flags.

   * Fixed comparison of `DATE' and `TIME' values with `NULL'.

   * Changed language name from germany to german to be consistent with
     the other language names.

   * Fixed sorting problem on functions returning a `FLOAT'.
     Previously, the values were converted to `INT's before sorting.

   * Fixed slow sorting when sorting on key field when using
     `key_column=constant'.

   * Sorting on calculated `DOUBLE' values sorted on integer results
     instead.

   * `mysql' no longer needs a database argument.

   * Changed the place where `HAVING' should be. According to ANSI, it
     should be after `GROUP BY' but before `ORDER BY'. MySQL Version
     3.20 incorrectly had it last.

   * Added Sybase command `USE DATABASE' to start using another
     database.

   * Added automatic adjusting of number of connections and table cache
     size if the maximum number of files that can be opened is less
     than needed.  This should fix that `mysqld' doesn't crash even if
     you haven't done a `ulimit -n 256' before starting `mysqld'.

   * Added lots of limit checks to make it safer when running with too
     little memory or when doing weird queries.
