The ws module have been plagued with build failures that was caused by it's optional compilation of binary add-ons. It used an installation hack instead of using optionalDependencies for it. Now if optional dependencies work correctly.. There shouldn't be any more build failures because of the binary addon building failed.
And as you might have noticed, we moved the repository to a new organization: websockets this allows us to more easily onboard people, split up everything in to more tiny maintainable modules etc.
