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 5.2.1 Released

The PHP development team would like to announce the immediate available for PHP 5.2.1. This release is a major stability and security enhancement of the 5.X branch, and all users are strongly encouraged to upgrade to it as soon as possible. Further details about this release can be found in the release announcement 5.2.1, the full list of changes is available in the ChangeLog PHP 5. Security Enhancements and Fixes in PHP 5.2.1: Fixed a possible safe_mode & open_basedir bypasses inside the session extension. Prevent search engine from indexing the phpinfo() page. Fixed a number of input processing bugs inside the filter extension. Fixed unserialize() abuse on 64 bit systems with certain input strings. Fixed possible overflows and stack corruptions in the session extension. Fixed an underflow inside the internal sapi_header_op() function. Fixed allocation bugs caused by attempts to allocate negative values in some code paths. Fixed possible stack overflows inside zip, imap & sqlite extensions. Fixed several possible buffer overflows inside the stream filters. Fixed non-validated resource destruction inside the shmop extension. Fixed a possible overflow in the str_replace() function. Fixed possible clobbering of super-globals in several code paths. Fixed a possible information disclosure inside the wddx extension. Fixed a possible string format vulnerability in *print() functions on 64 bit systems. Fixed a possible buffer overflow inside mail() and ibase_{delete,add,modify}_user() functions. Fixed a string format vulnerability inside the odbc_result_all() function. Memory limit is now enabled by default. Added internal heap protection. Extended filter extension support for $_SERVER IN cgi AND apache2 SAPIs. 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 and in shared hosting environments based on Apache module even local exploits can present a critical danger. Therefor we strongly advise all users of PHP, regardless of the version to upgrade to 5.2.1 release as soon as possible. For users upgrading from PHP 5.0 and PHP 5.1 there is an upgrading guide available here, detailing the changes between those releases and PHP 5.2.1.

PHP Manual Updates

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.
