This is important. In a release scheme where a new version is out regularly, you want to be able to easily point to specific, stable, old version by just saying "this has been available since GTK 27" instead of having to know that at the 27 major number, the stable version is 13, so you need that specific knowledge to be able to say "this has been available since GTK 27.13". The RC, alpha, beta releases are just steps towards the stable release, which is the only version that remains.

I was very much pushing for a single version number, but there was some hesitation to it. I'll try again when we discuss it next.
