The difference between the two HBA firmware

[Chase123]

I would like to know the difference between the following two firmware.
One is CRITICAL, and the other is RECOMMENDED.
I looked at all the "Revision History" and "Release Note", I can't find any difference.
Who can help me to see the difference between these two firmware?

** CRITICAL ** HPE Firmware Online Flash for QLogic Fibre Channel Host Bus Adapters - Microsoft Windows Server 2012R2/2016/2019 (x86_64)
Version:2019.12.05(2 Apr 2020)

* RECOMMENDED * HPE Firmware Online Flash for QLogic Fibre Channel Host Bus Adapters - Microsoft Windows Server 2016/2019 (x86_64)
Version:2019.12.03(9 Mar 2020)

My only thought is that 2019.12.03 doesn't support Windows 2012 R2 where as 2019.12.05 does.
