Bugs fixed:
Security Fix:
If a user has access to MyISAM table
t, that user can create a
MERGE table m that
accesses t. However, if the user's
privileges on t are subsequently
revoked, the user can continue to access
t by doing so through
m. If this behavior is undesirable,
you can start the server with the new
--skip-merge option to disable
the MERGE storage engine.
