This is also 64-bit.

That's the latest that GHA currently has. We've been testing 3.10.0 on AppVeyor.

Updated 1814

Fix #1839 in a ham-fisted way.

There is probably a more elegant solution.

Unfortunately this drops 2.7 binaries because there is no image that has both. However, from pypistats.org, it appears that our Python 2 user base is finally under 10%.

Also removes the Google groups embedding from the main web page because that no longer works.

Fixes #1822

Patch libev and c-ares configure scripts for M1

This updates the config.sub and config.guess files
for libev and c-ares to the versions that are packaged
with automake 1.16.5. This pulls in a version compatible
with Apples aarch64 chip.

Update the appveyor download url for pypi2.7-v7.3.1

M1 uses arm64 as a cpu identifier. This is not understood
by the two configure scripts, but appears to work when patched.

manylinux: disable -ffast-math

Support 3.10 now that the ABI is officially stable with 3.10rc1

It doesn't seem to crash locally. Not sure what's going on, but I doubt that's an important use-case (mixing gevent, threads and subinterpreters).

Change the way we detect compiled types to fix this.

Thanks to @denik for passing this on.

Get CI back in shape

Also try to opt-in to newer Python versions on AppVeyor, where possible.
