RTD stuck on master branch?

[The-Compiler]

https://github3.readthedocs.io seems to redirect to https://github3.readthedocs.io/en/master/, but those docs are outdated (see e.g. release notes which are missing v2.0.0 and v3.0.0).

Trying to look at https://github3.readthedocs.io/en/main/ instead leads to a 404.
