I guess there will be no “official”, but only a custom recovery image by the community. There has already been made some progress to port TWRP to the FP2.
There is a software issue report, which was updated just 3 days ago.
I don’t know if a description of how they fixed issues will be easy to create or can be written clearly presentable, short enough and understandable for those people reading it. And I’m not sure if there are enough people interested in these technical details at all. Anyway, that would probably be something for the DEV category in the forum rather than the support site or the blog.
I think it’s more or less clear from @paulakreuzer’s post and link how the status is: Bugs and software update are probably handled with priority at the moment and then they may put more emphasis on the OSOS again. I think that when they have news on the OSOS, they will share it. As we haven’t heard of anything in this direction the last few days, there might just be nothing new.
