The team is making excellent progress on the 1.7 release. We've got 19 issues resolved of the approximately 50 issues posted for this release - and the new CiviEvent component is starting to take shape.
We are targeting code-freeze / alpha release for the end of February, and there's still quite a lot to do. Hence, our plates are getting pretty full in terms of additions for 1.7. That said, if you have critical requirements or fixes that aren't already on the list, speak up! If you're able to pitch in with some code, and engineering resource and/or detailed specifications - that's a big plus.
