Not AFAIK. It’s listed in both the official announcement topic that I linked here in the Forum and on the Release Notes & Firmware page, but my v2.5x app is showing me a possible upgrade from 4.51.1.8444 to 4.51.2.0379, so I don’t know what to tell you. I think you did the right thing by asking about it in the firmware release announcement topic, because I certainly have no answer.
