Rock 5B+ Maintained?

Is this board still maintained? I was wanting to nab it for an android project. I noticed there is only an android 12 sdk available.

Is that all that will be supported for android?

Is there working/work in progress android 14 source/sdk anywhere for it?

If no further android development is being done, how stable/functional is the android 12 sdk/release?

Any info is appreciated!
