Last I checked, the Godot devs. seem to be treating the concept of Alpha, Beta, ect... differently compared to many other projects. The articles they posted on the website simply states that the main targets are all there and nothing more in terms of new stuff will be added (outside of pull requests discussed ahead of time).
It also makes it ever clearer that the team is serious when they say a version is not ready for heavy production. 3.x meanwhile appears pretty darn stable at the moment, I have been busy with other things, but I have, so far, encountered no notable bugs in my project that required a major workaround.
