Guys, just use the release candidates. There are some hard bugs left and a rush on QA does certianly not help, if we need a 1.3.1 short after. The many releases are done, because it is so difficult to corner them.
So it does not matter much when the official release is, as long the update path stays fluid. Just take a look at the GitHub Milestone for 1.3 and see how many tickets are left. Even better, if you can contribute debugging and reproduce stuff, it speeds up getting the release ready.
