Submission + - PHP 5.3 released (php.net)
Parker Lewis writes: "PHP 5.3 is finally released, with some long waited features like namespaces (with the unpopular backslash as namespace separator), late static binding, closures, optional garbage collection for cyclic references, new extensions (like ext/phar, ext/intl and ext/fileinfo), over 140 bug fixes and much more. As you can imagine, some old pieces will be broken."
