With every new Zend Studio release (still beta) comes a new PDT version: this time based on Eclipse 3.5 Galileo.
While Eclipse Galileo brings some nice new features and bug-fixes (of which many are not important to PHP developers, but nonetheless) PDT actually impresses the most with PHP 5.3 support: syntax coloring and validation with namespaces awareness. More about this in the release notes.
The best news in my opinion: since the software/plugin/update manager of Eclipse underwent some major refactoring, it’s biggest disadvantage may as well disappear! The only sane way to upgrade from 3.4 (or older) to 3.5 is still: delete your old version and unpack the new one, but lets hope this was the last time…
And last but not least: Mylyn integration got even better (I really need to dedicate a post to this).
Be sure to try the new PDT version!
