I don't know what's going on with the windows builds, they appear to be working fine in the maintenance branch.

I restarted them, and they still failed. There are no obvious changes with respect to reserved1 and reserved2, and cibuildwheel was released three weeks ago. The last nightly built without problems two days ago.

Could miniforge be a problem?

The fail comes in the repair process. There was a delvewheel release about ten days ago. Not sure if that's related. I wouldve expected the really recent builds to have failed as well.

I just released 2.0.2 and all the wheels built. If there was an upstream change it would need to be pretty recent.

We weren't the only ones having problems: adang1345/delvewheel#56.

There was a new release (1.8.1) yesterday, maybe that is the problem. We could try pinning the version in tools/wheels/cibw_before_build.sh

OK, the windows problem is fixed. There was a timeout on cirrus. I've been planning on adding

timeout_in: 90m

to the tasks, timeouts are fairly frequent. See https://cirrus-ci.org/faq/.

Thanks Andrew.

Thank you both, I really appreciate the prompt attention!
