We are down to 9 unresolved issues left before releasing 4.4. Given the current progress, it should be possible to release jBPM 4.4 on June 4th; the date is of course tentative and subject to change. Right now the only blocker issue is JBPM-2872: fix hudson db job. All others are deferrable if not completed on time.
If you feel like there is an issue that should not be left out, the time to bring it up is now. Visit the developers forum if you want to do so.
