3.6.9 tonight. Probably 3.6.10 next week, as that should give enough time for people to get it working if they still haven't.
And after that, I'd prefer to stick to 3.6.10 because, simply put, we need to use it if we want it to be better. Many of the bugs we found back when we first tested it out have already been fixed, and it's due time to start finding new ones. Also, if for some reason anyone is completely unable to get it working, then please mantis and/or talk to taylor about your problems so they can be fixed.
