Current status of builds and ports?

Hi everyone,

I’d like to support the continued existence of FireFox OS as a user and tester, i.e. I can install a build, test it, feedback, bug, etc.

But which ports are currently being maintained? Is the devices page still correct when it says Flame, Z3 and Z3 Compact are the official reference devices? Which of these is the most relevant?

It’s actually quite confusing that the main B2G OS page actually links to a different page about B2G OS phones:

The compatible devices page seems the one that’s most up to date but I’m still confused.
