#8586 has been merged, next step on our end here is setting up the CDN to serve the hashed pages from storage.

tuf==1.0.0 has been released: https://pypi.org/project/tuf/1.0.0/

I may be mistaken, but it looks like movement on PEP 458 has slowed -- what can we do to help get it moving again? Should I be watching https://github.com/jku/repository-playground or helping test #10870 or #8955 or #7488? Thanks!

Please let me know if I can help.

Hi, @brainwane and @ofek.
Helping to review and test PR #10870 for the TUF initialization for development would be great. 🙂
