Today we finalized the upgrade of PHP to 5.2.11 across our shared hosting servers. Customers should not see any changes or issues with their sites, but if you notice anything let us know.

Security Enhancements and Fixes in PHP 5.2.11:

* Fixed certificate validation inside php_openssl_apply_verification_policy.
* Fixed sanity check for the color index in imagecolortransparent().
* Added missing sanity checks around exif processing.
* Fixed bug #44683 (popen crashes when an invalid mode is passed).

Further details about the PHP 5.2.11 release can be found in the release announcement, and the full list of changes are available in the ChangeLog.
