Changes in release 3.23.36
--------------------------

   * Fixed a bug that allowed you to use database names containing a `.'
     character.  This fixes a serious security issue when `mysqld' is
     run as root.

   * Fixed bug when thread creation failed (could happen when doing a
     LOT of connections in a short time).

   * Fixed some problems with `FLUSH TABLES' and `TEMPORARY' tables.
     (Problem with freeing the key cache and error `Can't reopen
     table...').

   * Fixed a problem in Innobase with other character sets than `latin1'
     and another problem when using many columns.

   * Fixed bug that caused a core dump when using a very complex query
     involving `DISTINCT' and summary functions.

   * Added `SET TRANSACTION ISOLATION LEVEL ...'

   * Added `SELECT ... FOR UPDATE'.

   * Fixed bug where the number of affected rows was not returned when
     `MySQL' was compiled without transaction support.

   * Fixed a bug in `UPDATE' where keys weren't always used to find the
     rows to be updated.

   * Fixed a bug in `CONCAT_WS()' where it returned wrong results.

   * Changed `CREATE ... INSERT' and `INSERT ... SELECT' to not allow
     concurrent inserts as this could make the binary log hard to
     repeat.  (Concurrent inserts are enabled if you are not using the
     binary or update log).

   * Changed some macros to be able to use fast mutex with glibc 2.2.
