The improvements sound great.
I did not look through the details, but it's strange that one of the features is that Cloudflare R2 will be used to improve download speeds and reduce API calls to Github while at the same time adding a new requirement of adding a personal Github API token.
Hopefully one day the Github requirement will be removed. It would be nice if projects/code stored on Gitlab, Codeberg, or other Git services like Gitea or Forgejo could be used without having to mirror/fork the project onto Github.
