V7 basic questions

Hi there, longtime user (still have TNG 1.0.0 installer) but returning after a 7+ year hiatus.

I’m wondering what is the latest stable V7 release? There is only development version 7.1.35 listed on the downloads page, and no stable versions. I gather from browsing the forum that V7 is not being developed any more, but would appreciate some final definitive information about it.

And the manual is still truly the ancient 3.1.17 that I already have from 2016?

Just would appreciate a comprehensive V7 wrapup. Thanks!
