Fixed that databasename works as second argument to mysqlhotcopy.

The values for the UMASK and UMASK_DIR environment variables now can be specified in octal by beginning the value with a zero.

Added RIGHT JOIN. This makes RIGHT a reserved word.

Added @@IDENTITY as a synonym for LAST_INSERT_ID(). (This is for MSSQL compatibility.)

Fixed a bug in myisamchk and REPAIR when using FULLTEXT index.

LOAD DATA INFILE now works with FIFOs. (Patch by Toni L. Harbaugh-Blackford.)

FLUSH LOGS broke replication if you specified a log name with an explicit extension as the value of the log-bin option.

Added BACKUP TABLE and RESTORE TABLE.

Fixed core dump on CHANGE MASTER TO when the slave did not have the master to start with.

The slave now logs when it connects to the master.

Fixed bug in mysqldump from 3.23 which caused some CHAR columns not to be quoted.

Merged analyze, check, optimize and repair code.
