The majority of the security vulnerabilities discovered and resolved can in most cases be only abused by local users and cannot be triggered remotely. However, some of the above issues can be triggered remotely in certain situations, or exploited by malicious local users on shared hosting setups utilizing PHP as an Apache module. Therefore, we strongly advise all users of PHP, regardless of the version to upgrade to the 5.2.1 or 4.4.5 releases as soon as possible.
For users upgrading to PHP 5.2 from PHP 5.0 and PHP 5.1, an upgrade guide is available here, detailing the changes between those releases and PHP 5.2.1.

The front page has changed
[08-Feb-2007] The news on the front page of php.net has changed, the conference announcements are now located on their own page. The idea is to keep php.net specific news clear and also opens the door for additional news entries, like for RC releases. More changes are on the way so keep an eye out.
PHP Manual Updates
[03-Feb-2007] The PHP documentation team is proud to present to the PHP community a few fixes and tweaks to the PHP Manual, including:
- an improved, XSL-based build system that will deliver compiled manuals to mirrors in a more timely manner (goodbye dsssl)
- manual pages can now contain images (see
imagearc()for an example) - updated function version information and capture system (fewer "no version information, might be only in CVS" messages)
- ... and more to come!
Please help us improve the documentation by submitting bug reports, and adding notes to undocumented functions.
