Someone (in good spirit) should create a new thread, people obviously don't read the header, H2 2022 is gone since a while...
This threads were intended for future research, which is troublesome if the content does not fit the time frame, or doesn't contain
pure release infos at all. (tests and bugs and whatever else does not fit here and just bloats them up)
