The first release candidate of PHP 5.4 was just released. The announcement on the main page is still missing, but the links are the usual ones: http://www.php.net/archive/2011.php#id2011-11-10-1
Today, I gave a presentation on Traits for PHP in Paris. It was a quite interesting audience, ca. 35 professional PHP developers and all interested in Traits.
PHP 5.3 is already released for a while and starts to settle in.
Finally, I managed to complete the changes for the traits patch. Since, PHP 5.3 already entered the release cycle and it is not sure whether there will be a PHP 5.4 with new language features, the new patch is written for the PHP6 codebase.
