Hi!

MySQL 3.21.26 is only a minor bug fix release.

>From the Changelog:

   * from_days(0) now returns "0000-00-00"

   * In DATE_FORMAT() PM and AM was swapped for hours 00 and 12.

   * Extended the default max key size to 256.

   * Fixed bug when using BLOB/TEXT in GROUP BY with many tables.

   * A enum field that is not declared NOT NULL has NULL as default
     value.  (Before the default value was the first enum option)

   * Fixed bug in the join optimizer code when using many part keys on
     the same key:  INDEX (Organisation,Surname(35),Initials(35)).

   * Added some tests to the table order optimizer to get some cases
     with 'SELECT ...  FROM many_tables' much faster.

   * Added a retry loop around accept() to possible fix some problems
     on some Linux machines.

Yours,
Monty
