Cert-schema 2.x.x missing from pypi.org

I noticed recently that cert-schema 2.x.x is pissing from pypi.org repository. The only versions available are two 3.0.0.x pre-releases. Does anybody know if this has been done on purpose and what the direction of cert-schema project is?

The following error is also returned by pip install:
ERROR: Could not find a version that satisfies the requirement cert-schema>=2.1.5
ERROR: No matching distribution found for cert-schema>=2.1.5

Thank you,

Thank you for the heads up on this. This arose from a PyPI issue that we had a little while back. I thought I had fixed it, but it turns out to have wiped out some of our 2.x builds. I have replaced cert-schema with a new version, 2.1.7. Please let me know if you continue to have dependency resolution issues.
