On the [main PHP.net site]http://php.net/() today they've announced the release of new released of all currently supported versions of the language:
All of these releases contain similar bugfixes correcting security issues reported in the language including problems in the CLI server, Phar handling, Zip functionality and the Opcache feature. It is suggested to update to these latest versions as soon as possible to prevent issues with these bugs.
As always you can download the source versions of these latest releases from the main downloads page or the Windows binaries from windows.php.net. If you're interested in the changes made, check out the Changelogs for PHP 7 and PHP 5.6.
