Question ASRock AB350 PRO4 ATX Motherboard has AGESA - BIOS Version 5.60. Is there a change log available (and more)?

I noticed about 3 weeks ago that this BIOS update was available but the AGESA version confused me until today.

After further research on AGESA I learned that this seems to indicate support for the upcoming AMD Ryzen 3000 series of CPU's.
The ASRock support site mentions support for the low end Athlon 2xxGE series APU's but made no mention of the 3000 series support.

My question is: Is there a detailed change log somewhere so I can know whats new with this BIOS release besides support for the 3000 series and 2xxGE CPU's?

The second question is: Can we confirm that since the BIOS now supports AGESA on the ASRock AB350 PRO4 ATX Motherboard that the upcoming 3000 series Ryzen CPU's are now supported?
Another update ASRock will release BIOS version 5.80 this month (May 2019) for the ASRock AB350 PRO4 that will enable support for the AMD Ryzen 3000 CPU's.

TAIPEI, Taiwan, May 6th, 2019 – ASRock has announced BIOS updates for AMD X470/B450/X370/B350 and A320 series motherboards to support the soon to be released new AMD Ryzen processors. The latest BIOS update will be available for download from our website or simply update through ASRock APP Shop.


EDIT: As of June 7th, 2019 ASRock has not released BIOS version 5.8x, I will update this thread when it is available.

Another update it seems the new UEFI BIOS update supports the following CPUs.

AMD Ryzen

R5-3600 6c/12t
R5-3600X 6c/12t
R7-3700X 8c/16t
R7-3800X 8c/16t

There is no official support for the Ryzen 3900X or 3950X.

UPDATE 07-14-2019: ASRock's AB350 PRO4 claims it can support the R9-3900X 12 core / 24 thread CPU but I would be worried about the rather basic VRM setup if someone was wanting to try overclocking.
