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.)

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

Merged analyze, check, optimize and repair code.
