When we originally added win arm64 wheels part of our decision was that we would remove it if the underlying CI infrastructure proved problematic. Unfortunately, that time has already arrived. We need to do a release today for an OpenSSL security release and the arm64 windows image has been broken with Python 3.14t for over two weeks. Working around issues like this in our CI is not desirable or acceptable. Accordingly, we are removing wheels effective with our next point release.

Our apologies to the users of these wheels, but the most effective thing you can do is advocate with GitHub to have windows arm64 treated like a first class citizen in Actions.

We do as well. If you've got colleagues who you can point at this issue, we'd really like folks to understand that having stable CI is one of our apex requirements -- waiting 2 weeks for this to be resolved was well beyond our norm, ordinarily we consider reverting things after a single day. For the ARM64 ecosystem on Windows to be something we can support, it's stability needs to be a priority.

@alex Yeah, we are looking for the best eyes to put on this issue. The Arm folks are continuing their investigation, while we seek additional help. It seems the issue has turned out to be more complicated than we initially thought.
