On April 2nd 2014, the PHP group has released PHP 5.5.11 :
Several bugs were fixed in this release, some bundled libraries updated and a security issue has been fixed : CVE-2013-7345. We recommand all PHP 5.5 users to upgrade to this version.
As a consequence, PHP 5.5.11 packages are now available on Dotdeb for Debian 7.4 “Wheezy”, on both amd64 and i386 architectures.
And don’t forget: if you find Dotdeb useful, you may want to show your support.
