• Fixed buffer overflow problem if someone specified a too long datadir parameter to mysqld
• Add missing <row> tags for mysqldump XML output.
• Fixed problem with crash-me and gcc 3.0.4.
• Fixed that @@unknown_variable doesn't hang server.
• Added @@VERSION as a synonym for VERSION().
• SHOW VARIABLES LIKE 'xxx' is now case-insensitive.
• Fixed timeout for GET_LOCK() on HP-UX with DCE threads.
• Fixed memory allocation bug in the glibc library used to build Linux binaries, which caused mysqld to die in 'free()'.
• Fixed SIGINT and SIGQUIT problems in mysql.
• Fixed bug in character table converts when used with big ( > 64K) strings.
• InnoDB now retains foreign key constraints through ALTER TABLE and CREATE/DROP INDEX.
• InnoDB now allows foreign key constraints to be added through the ALTER TABLE syntax.
• InnoDB tables can now be set to automatically grow in size (autoextend).
• Our Linux RPMS and binaries are now compiled with gcc 3.0.4, which should make them a bit faster.
• Fixed some buffer overflow problems when reading startup parameters.

• Fixed problem with SHOW CREATE TABLE and PRIMARY KEY when using 32 indexes.
• Fixed that one can use SET PASSWORD for the anonymous user.
