The v0.14.8 release doesn't include a Windows build because today (of all days!) the windows-2016 runner was removed:

The windows-2016 environment is deprecated and will be removed on April 1st, 2022.
Migrate to windows-2019 or windows-latest instead.
For more details see https://github.com/actions/virtual-environments/issues/5238

We did these changes for the upcoming 0.15.0 release in #4248, so that's not affected. However, to make a 0.14.8 release, we'll need to update windows to 2019.
