Release 0.810 planning

[JukkaL]

I'm going to release mypy 0.810 soon, using an accelerated release process (likely Feb 10 or Feb 11). This is a small release that only includes #9992, which fixes a regression in 0.800.

This is not going to be called 0.801, since the fix includes a behavior change and a new command-line option.

Wheel builds are broken (example: https://github.com/mypyc/mypy_mypyc-wheels/runs/1873417540). This is likely related to the removal of the typeshed git submodule.

Oh well. I'll try to fix the builds tomorrow. Everything else is fine.

This got accidentally closed.

Still having some issues with the wheels. Hopefully I can get them sorted soon.

I accidentally pushed the version tag before validating the wheels, so the actual release will be 0.811 instead of 0.810.

If I can't fix the wheel build soon, I'll call it a day and continue on Monday.

One blocking question: #10073 (comment)

[emmatyping]

I think it would be good to get #10086 into either 0.810 or a 0.811 bugfix if it's too late for 0.810.

[hauntsaninja]

0.810 won't include any modular typeshed changes :-)

The release wheel build works now. I'm going to wait a bit for the wheel build to be unbroken on master (just as a general precaution). However, I'm not going to wait longer than until Tuesday or Wednesday.
