Changes in release 3.20.14
--------------------------
* If one gives `-p' or `--password' option to `mysql' without an
argument, the user is solicited for the password from the tty.
* Added default password from `MYSQL_PWD' (by Elmar Haneke).
* Added command `kill' to `mysqladmin' to kill a specific MySQL
thread.
* Sometimes when doing a reconnect on a down connection this
succeeded first on second try.
* Fixed adding an `AUTO_INCREMENT' key with `ALTER_TABLE'.
* `AVG()' gave too small value on some `SELECT's with `GROUP BY' and
`ORDER BY'.
* Added new `DATETIME' type (by Giovanni Maruzzelli
<maruzz@matrice.it>).
* Fixed that define `DONT_USE_DEFAULT_FIELDS' works.
* Changed to use a thread to handle alarms instead of signals on
Solaris to avoid race conditions.
* Fixed default length of signed numbers. (George Harvey
<georgeh@pinacl.co.uk>.)
* Allow anything for `CREATE INDEX'.
* Add prezeros when packing numbers to `DATE', `TIME' and
`TIMESTAMP'.
* Fixed a bug in `OR' of multiple tables (gave empty set).
* Added many patches to MIT-pthreads. This fixes at least one lookup
bug.
