Changes in release 3.21.2
-------------------------

   * The range optimizer is coded, but only 85% tested. It can be
     enabled with `--new', but it crashes core a lot yet...

   * More portable. Should compile on AIX and alpha-digital.  At least
     the `isam' library should be relatively 64-bit clean.

   * New `isamchk' which can detect and fix more problems.

   * New options for `isamlog'.

   * Using new version of Automake.

   * Many small portability changes (from the AIX and alpha-digital
     port) Better checking of pthread(s) library.

   * czech error messages by <snajdr@pvt.net>.

   * Decreased size of some buffers to get fewer problems on systems
     with little memory.  Also added more checks to handle "out of
     memory" problems.

   * `mysqladmin': you can now do `mysqladmin kill 5,6,7,8' to kill
     multiple threads.

   * When the maximum connection limit is reached, one extra connection
     by a user with the *PROCESS_ACL* privilege is granted.

   * Added `-O backlog=#' option to `mysqld'.

   * Increased maximum packet size from 512K to 1024K for client.

   * Almost all of the function code is now tested in the internal test
     suite.

   * `ALTER TABLE' now returns warnings from field conversions.

   * Port changed to 3306 (got it reserved from ISI).

   * Added a fix for Visual FoxBase so that any schema name from a table
     specification is automatically removed.

   * New function `ASCII()'.

   * Removed function `BETWEEN(a,b,c)'. Use the standard ANSI syntax
     instead: `expr BETWEEN expr AND expr'.

   * MySQL no longer has to use an extra temporary table when sorting
     on functions or `SUM()' functions.

   * Fixed bug that you couldn't use `tbl_name.field_name' in `UPDATE'.

   * Fixed `SELECT DISTINCT' when using 'hidden group'. For example:
          mysql> SELECT DISTINCT MOD(some_field,10) FROM test
                     GROUP BY some_field;
     Note: `some_field' is normally in the `SELECT' part. ANSI SQL
     should require it.
