The PHP development team announces the immediate availability of PHP 5.4.30. Over 20 bugs were fixed in this release, including the following security issues: CVE-2014-3981, CVE-2014-0207, CVE-2014-3478, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487, CVE-2014-4049, CVE-2014-3515. All PHP 5.4 users are encouraged to upgrade to this version.
Please, note that this release also fixes a backward compatibility issue that has been detected in the PHP 5.4.29 release. Still, the fix in PHP 5.4.30 may break some very rare situations. As this tiny compatibility break involves security, and as security is our primary concern, we had to fix it. This concerns bug 67072. For more information about this bug and its actual resolution, please refer to our upgrading guide, section 4a. We apologize for any inconvenience you may have experienced with this behavior.
