The final build of NetBeans 7.0 is now available. You can download it from NetBeans site. Although NetBeans IDE 7.0 introduces language support for coding to the proposed
Java SE 7 specification with the JDK 7 developer preview, it also contain few features for PHP developers. The list of all main new things is here.
In the list is mentioned Generate PHP Doc in the PHP section, but you should be aware that PHP Documentor doesn't support PHP 5.3 yet.Hopefully it will be soon.
Every feedback is welcome. Now we are working on a small bug fix release that should be available soon, so if you find an issue, please enter it into our Bugzilla.
