Confusion on state of APM

What is the current version of APM.

I see on the home page under news that APM 3.2 is in beta, but then here and there I see 3.2 has been released. I see the title of APM 3.2 is like RC14… (release candidate), and then I see 3.2 stable.

I am confused. Is the the official news page for this flight controller?

Seems every where I try to look I get different indicators as to what is up.

Github shows 3.2.1 as an active branch…

What is the official word on this?
