I think the powerpc64 code is in good shape now, and ready for release. Are you aware of anything that needs fixing?
No, all what I can think of are a couple of issues that make the powerpc64 code more stable (you can check their merge requests in the repo).
One problem with the current state is that big-endian arm is most likely broken. I don't want to delay the release for that though, since I'm not able to fix it. If anyone is able to test and fix, soon would be a good time for it (but I'd consider a bug-fix release with just those fixes anytime later).
I also delayed the big-endian support of GHASH algorithm for Aarch64 because I don't have access to big-endian device for testing. Do you think using cross-compile and qemu for the test would work? If so I will gladly contribute with those fixes.
