Packages and versions can be deleted from PyPI, which can be a massive pain in the ass for anyone consuming these packages. Can have your whole Python dependency tree pinned => author pulls a package version => builds broken. As part of StableBuild (
https://www.stablebuild.com) we create full daily snapshots of the PyPI registry - so figured it would be nice to make an overview of deleted packages/versions and make the wheels available for download.
E.g. jaxlib 0.4.4 was removed a few days back: https://dashboard.stablebuild.com/pypi-deleted-packages/pkg/... => can download the wheels for free w/o registration
