MySQL Reference Manual for version .

Added -p# (remove # directories from path) to isamlog. All files are written with a relative path from the database directory Now mysqld shouldn't crash on shutdown when using --log-isam.
New mysqlperl version. Is now compatible with msqlperl-0.63.
New DBD module available in Contrib/
Added group function STD() (standard derivation).
The mysql server is now by default compiled without debugging information. This will make the daemon smaller and faster.
Now one usually only have to give --basedir to mysqld. All other paths are relative in a normal installation.
BLOBs contained sometimes garbage when used with a SELECT on more than one table and ORDER BY.
Fixed that calculations that are not in GROUP BY works as expected. (ANSI SQL extension) Example: SELECT id,id+1 FROM table GROUP BY id
The test of using MYSQL_PWD was reversed. Now MYSQL_PWD is enabled as default in the default release.
Fixed convert bug which got mysqld to core dump with Aritmetic error on Sparc-386
Added option --unbuffered to mysql. (For new mysqlaccess)
When using overlapping (unnecessary keys) and join over many tables the optimiser could get confused and return 0 records.
