Android Question Some questions from returning user

Hello,

I purchased B4A a few years back and happily messed around with it for a while, then I sort of got away from it. I came back and saw it has become free and I have a few questions:

1. Should I import my old appkey or create a new one?

2. Will the software still be receiving updates and such?

3. Where can I find the most up to date tutorials?

4. Who now owns B4A?

Thanks in advance,
Matt
