Just installed a wheel (win64 + py38) successfully. I think this should be included in release 1.7.

Thank you so much! @snnn

Quick questions: does this mean we'll need wheel-builder for Linux packages and this for windows packages? if yes, shall we put them in one place please?

That will be better. But it will take me a few days more and I think currently the top priority thing is the 1.7 release and retiring appveyor.

I'm merging it.

@chinhuang007 please kindly document this as part of your updated release experience, so that it will help the next release manager. Hopefully, we'll fix these issues before that though. :)

[chinhuang007]

@linkerzhang Sure, I will certainly document the steps we are going through for 1.7 release. It should be smoother next time!

[chinhuang007]

@snnn Thanks for providing the solution! I don't see anything in Actions for the release workflow, the workflow or the files. Do I need certain permissions?

[snnn]

Please try to create a rel-1.7.0 branch. The action only works on release branches.

[chinhuang007]

@snnn Thanks for the explanation. I will create a rel-1.7.0 branch tomorrow and verify.

[chinhuang007]

@snnn I created the release branch last night and saw the workflow in Actions. But I don't know where to find Windows wheels, as you shared in your branch. Please help clarify if I missed anything?

Thanks for providing the zip for Windows wheels. The next question is how can I generate and see the zip myself when something happens to the release branch (for ex. I am merging a couple of PRs from master to rel-1.7.0)? Should I also ask you to provide the file next time?

Ah, somehow I didn't get to see this before. Thanks for pointing it out.
