We retagged Python 3.5.0rc1 today to fix two bugs that popped up late in the process. Release candidates are supposed to be software you genuinely would release, and I couldn't release Python with both those bugs. This delay rippled through the whole process, so it just isn't going out tonight (late Sunday / early Monday in my timezone). I have every expectation it'll go out Monday.
In case you're interested, the bugs are (were!):
My thanks to the folks who stepped up and fixed the bugs on short notice, and my apologies to the community for the delay. We're just trying to make the best Python we can, for yooooooooou!
See you tomorrow,
