Is GCCGO still active?

I was wondering if gccgo is still active. As per this Github repository, there seems to be some activity; the last commit was made 1 month ago for a bug fix:

Is gccgo still in active development? If not, what happened?

Is GCCGO considered a stable and reliable option for Go programming, or are there concerns about using it in production?

I am trying to learn about GCCGO, including whether it was ready for production. Could you please elaborate on how this is considered production ready?
