Why is the latest v8 and not v11?

[AnsisMalins]

The short answer is "because v11 does not build", but is there more context or story to this? What is the state of the project and what can I expect in the near and far future?

The error I got when trying to build v11 on and for Windows myself:

# code.forgejo.org/forgejo/runner/v11/act/artifactcache
act\artifactcache\handler.go:28:20: undefined: syscall.Kill
