Beginning on 28 June 2011, the PHP Development Team implemented a timeline for the release of new versions of PHP.<ref name="PHP-2011">{{cite web|title=PHP: Release Process|url=https://wiki.php.net/rfc/releaseprocess|access-date=2013-10-06|date=2011-06-20}}</ref> Under this system, at least one release should occur every month. Once per year, a minor release should occur which may include new features. Every minor release should at least be supported for two years with security and bug fixes, followed by at least one year of only security fixes, for a total of a three-year release process for every minor release. No new features, unless small and self-contained, are to be introduced into a minor release during the three-year release process.
