Changes in release 3.20.11
--------------------------
* When using `SELECT ... INTO OUTFILE', all temporary tables are ISAM
instead of HEAP to allow big dumps.
* Changed date functions to be string functions. This fixed some
"funny" side effects when sorting on dates.
* Extended `ALTER TABLE' according to SQL92.
* Some minor compatibility changes.
* Added `--port' and `--socket' options to all utility programs and
`mysqld'.
* Fixed MIT-pthreads `readdir_r()'. Now `mysqladmin create database'
and `mysqladmin drop database' should work.
* Changed MIT-pthreads to use our `tempnam()'. This should fix the
"sort aborted" bug.
* Added sync of records count in `sql_update'. This fixed slow
updates on first connection. (Thanks to Vaclav Bittner for the
test.)
