Also note that we use Unfortunately, micromamba 2.0.0 seems to have been released in the last day, which broke something. I've opened mamba-org/mamba#3467 with some debug information. |

I pinned the micromamba version here, so now AppVeyor is running tests, though it looks like there might be some new failures. |
According to the SciPy toolchain roadmap [1], we should be supporting at minimum MSVC 2019. The AppVeyor image has been held back to MSVC 2017 (probably just forgotten since it didn't complain), which is starting to cause issues for more modern code.

Version 2 appears to be broken WRT installing PyPI packages: mamba-org/mamba#3467

I've pinned wxWidgets as well, which broke wxPython: conda-forge/wxpython-feedstock#125 and now we are building. |

Both projects say they have fixed their issues upstream, so I'm going to see if we can revert those. Edit: It looks like micromamba made their release, but haven't updated their "latest" link yet. So I've left the pin for now. |

PR summary
According to the SciPy toolchain roadmap [1], we should be supporting at minimum MSVC 2019. The AppVeyor image has been held back to MSVC 2017 (probably just forgotten since it didn't complain), which is starting to cause issues for more modern code. (Namely #28842 does not work even with the flag for new behaviour.)
There are many other software changes, so I'm opening this separately from #28842 just to confirm it doesn't break anything.
