@casevh, could you please share instructions, that seems to be working for you? So far we have docs/win_build.rst, mingw64/msys2_build.txt and windows_build.txt.

> I'll add to the Windows build document as time permits this week. If you would just update `msys2_build.txt` - this will be great.

@brubsby, now you are able to test pre-release version. Do you still have this issue with pycharm or it should be closed? The [latest sphinx documentation](https://gmpy2.readthedocs.io/en/latest/) is still not up...

Ok, I had a time to run this horrible beast. (All this on 2023.2.2, package was installed from CI wheels to workaround #438.) @casevh, probably we could close this issue....

@brubsby, v2.2 was release. Is this issue valid for you?

@tjb900, now there are binary wheels for 2.2.0a1. Can you reproduce the issue?

``` >>> import gmpy2 >>> gmpy2.mpz.__new__(gmpy2.mpz) mpz(0) ``` @casevh, probably you can close this issue.

> no, just this patch on top of the 2.1.5 release From https://github.com/aleaxit/gmpy/pull/422, correct? Then, there should be no test failures with our tests, e.g.: https://github.com/aleaxit/gmpy/actions/runs/6061180143/job/16446076083 (The "Build Wheels" workflow...

Yeah, I'm trying to do an update: https://github.com/skirpichev/gmpy/actions/runs/6083541455
