B.2.12. Changes in Release 4.0.20 (17 May 2004)

End of Product Lifecycle. Active development and support for MySQL Database Server versions 3.23, 4.0, and 4.1 has ended. For details, see http://www.mysql.com/about/legal/lifecycle/#calendar. Please consider upgrading to a recent version. Further updates to the content of this manual will be minimal. All formats of this manual will continue to be available until 31 Dec 2010.

Note

The windows packages had to be repackaged and re-released several times to resolve packaging issues (such as missing files). This did not affect the binaries included (they have not been recompiled), therefore the installation packages are of version 4.0.20d, while the binaries included still identify themselves as version 4.0.20b.

Functionality added or changed:

  • From the Windows distribution, predefined accounts without passwords for remote users ("root@%", "@%") were removed (other distributions never had them).

  • Phrase search in MATCH ... AGAINST ( ... IN BOOLEAN MODE) no longer matches partial words.

Bugs fixed:

  • A crashing bug (race condition) was fixed in InnoDB diagnostic logging. It was introduced in 4.0.19. (Bug#3596)

  • Fixed a bug in division / reporting incorrect metadata (number of digits after the decimal point). It can be seen, for example, in CREATE TABLE t1 SELECT "0.01"/"3". (Bug#3612)

  • Fixed a problem with nonworking DROP DATABASE on some configurations (in particular, Linux 2.6.5 with ext3 are known to expose this bug). (Bug#3594)

  • Fixed that in some replication error messages, a very long query caused the rest of the message to be invisible (truncated), by putting the query last in the message. (Bug#3357)
