Sorry to be the barer of bad news, but we've decided to delay the release of 0.12 by approximately a week. Several factors are leading to this...
1. We've discovered a potentially serious issue with the module API. Basically, the value named "id" that EVERY module relies has the ability of screwing up forms that are posted from PHP. It seems to only happen with form inputs with [] in them (basically, multi-select boxes), but we're not totally sure it's limited to that. Instead, I'm going to write a workaround to this (while retaining backwards compatibility) that will make the URLs a) prettier and b) work correctly in all cases. This one thing will require a few days of regression testing with various modules before it can considered finished.
2. I'm going away for most of next week to San Francisco for work. And I hate to release something right before I'm out of touch. If this thing starts doing something bad, I want to be around to be able to help resolve it. While 0.12 has been beta tested to death, it still hasn't been out there "in the wild" yet.
3. Westis is due back tomorrow (yay!). Since he understands the menus more than anyone else at this point, I need him to help write up some documentation on transitioning from cssmenu and ellnav to the menu manager. I'm also going to try and make sure cssmenu still works in 0.12, for those people that don't have to time to try to cut over to the new system. I'm also going to ask him to write a simple example of the bulletmenu template so that people's heads don't spin when they try to write/modify a template on their own.
4. We're finding a few more little things that can be worked on (well, that'll always happen), so we're going to try and get those in before hand as well.
So, what does that mean? It means we wait.

However, it also means this... If you have any little tweaks that you think 0.12 should have and won't either a) break the system or b) require more than 10-15 min of time to implement them, post them now. The little things are easy to get in and don't require a ton of testing to make happen.
0.12 should be a nice solid release. The people beta testing it seem to be pretty happy. However, we're just trying to "dot our I's and cross our T's", so to speak and make sure it's as good as possible.
Expect a release closer to the end of next week. I'm shooting for next Friday, but if I get home a little earlier, then possibly next Thursday.
Sorry for the delays and thanks for your patience!
