In a new note from PHP.net today, they announce the release of PHP 5.0.4 and 4.3.11.

The PHP Development Team would like to announce the immediate release of PHP 5.0.4 and 4.3.11. These are maintenance releases that in addition to non-critical bug fixes address several security issues. All Users of PHP are strongly encouraged to upgrade to one of these releases as soon as possible.

For changes in PHP 5.0.4 since PHP 5.0.3, please consult the PHP 5 ChangeLog. For changes in PHP 4.3.11 since PHP 4.3.10, please consult the PHP 4 ChangeLog.

There are a few new things in each of them including "Oracle Instant" support and SNMPv2 support (PHP 5.0.4 only). There are, however, a pretty long list of bug fixes that each version fixes, so go on over and get these latest updates...
