Ewout ter Hoeven

Thanks for getting back so quickly! So declaring `CIBW_BUILD: cp311-win_arm64` for example wouldn't be enough? Would it be nice if `CIBW_BUILD` implied `CIBW_ARCHS`? That would make build matrices less complex...

We could start with testing in CI and fixing bugs that come up earlier than that, right? NumPy, SciPy and Cython built are now building and testing fine on Python...

We're a far months further, so here a quick update on the ecosystem! Python 3.11 is now ABI stable with the release candidate series, which means wheels can be uploaded...

It looks like currently an error building 'statsmodels.tsa._innovations' extension [appears](https://github.com/quaquel/EMAworkbench/actions/runs/3213672441/jobs/5253509452#step:4:1886): Error log building Statsmodels with Python 3.11 on Ubuntu: ``` UPDATING build/lib.linux-x86_64-cpython-311/statsmodels/_version.py set build/lib.linux-x86_64-cpython-311/statsmodels/_version.py to '0.13.2' running build_ext building 'statsmodels.tsa._stl'...

I also opened an [draft PR](https://github.com/statsmodels/statsmodels/pull/8428) which tests Python 3.11 on the Azure pipelines CI, so that all errors can be detected there. See the first run [here](https://dev.azure.com/statsmodels/statsmodels-testing/_build/results?buildId=4662&view=results). **Edit:** Current...

Thanks for getting back! I found an abandoned PR over at the Cython repo that looked a lot like the error we're experiencing, so I [asked](https://github.com/cython/cython/pull/4672#issuecomment-1272556145) if it could be...

I found some more things. **Buidling** - With both Cython 0.29.32 and 3.0.0a11 the statsmodels main branch compiles fine on Python 3.11 🎉 - The latest release is of statsmodels...

The maintainer of patsy responded very quick and already tagged a [new release](https://github.com/pydata/patsy/releases/tag/v0.5.3), with the fix in it! I [retriggered the CI](https://dev.azure.com/statsmodels/statsmodels-testing/_build/results?buildId=4665&view=results), and the Linux and macOS jobs pass! On...

CI Is green and passing, so https://github.com/statsmodels/statsmodels/pull/8431 can be merged. The next step is indeed building and publishing wheels. Can we do an extra patch release on the 0.13.x branch...

So now we need to ship Python 3.11 support to users. We could either start backports to the 0.13.x branch, or prepare for 0.14.0 release. @bashtage what would be your...
