Following on the heels of these comments from Alexander Netkachev, the Zend Developer Zone has posted the full project plan for the next release of the PHP IDE Zend is working on, version 0.7.
The plan of the 0.7 version is based on the initial SRS which is available here. On top of that SRS many bugs were submitted together with enhancement requests that were/will be included in the 0.7 release. You can find all PHP IDE open bugs here.
The announcement is broken up into three sections - the release deliverables, the release milestones, and the target operating environments - each with plenty of details to show you exactly what the team is working towards.
