This is a Monthly Rapid Update release of the MySQL Enterprise Server 5.0.
Bugs fixed:
Important Change: Security Fix:
It was possible to circumvent privileges through the creation of
MyISAM tables employing the DATA
DIRECTORY and INDEX DIRECTORY
options to overwrite existing table files in the MySQL data
directory. Use of the MySQL data directory in DATA
DIRECTORY and INDEX DIRECTORY path
name is now disallowed.
Additional fixes were made in MySQL 5.0.70.
See also Bug#39277.
Incompatible Change:
It was possible to use FRAC_SECOND as a
synonym for MICROSECOND with
DATE_ADD(),
DATE_SUB(), and
INTERVAL; now, using
FRAC_SECOND with anything other than
TIMESTAMPADD() or
TIMESTAMPDIFF() produces a syntax
error.
It is now possible (and preferable) to use
MICROSECOND with
TIMESTAMPADD() and
TIMESTAMPDIFF(), and
FRAC_SECOND is now deprecated.
