According to this post from the Eclipse site (mailing list), the PHPIDE code for Zend's project is undergoing a legal review and is awaiting a "legal authorization code".

There's not much more information than that in the main post, but several of the commentators are wondering if this will cause a delay for the next code release, if it will affect the Zend Debugger as well, and if it was an expected legal review.

There's no response yet from Guy Harpaz, the original poster of the thread, but we'll keep you updated.
