I was preparing one, but upstream released an official 2.15 release. Which has an exhaustive test suite enabled in the build and passes (by upstream standards; there are scary messages but they're expected) on all architectures.
The delta is too big to sensibly check. But it's a proper release with upstream blessing etc. If I were release manager I'd wait for people to test it for a couple weeks, then (assuming all is okay) let it in. Your call though. Cheers, --Barak.
