Note about this update, while I do not have access to the release notes, I do know one thing about this update and this comes from my experience and talking to Mimosa earlier this week.
I had a sector automagically switch to a 6 GHz channel when I made a mistake in channel selection earlier this week. When I asked Mimosa they said 2.5.1 would be out soon to fix this issue. If you do not update to 2.5.1 soon I would recommend adding 5.926 GHz through 6.200 GHz as excluded channels on ALL United States Licensed 5 GHz Radios in your network, This could get you into a lot of hot water with the FCC and there are many private Licensed PTP links in that spectrum that, if you mess with, they will come at you with lawyers and cost you lots of money. We have several 6 GHz PTP Links and if anyone messed with us we would come after them, I can understand unintentional mistakes, but many companies will not when you effect their bottom line and their service adversely. TLDR:DO NOT OPERATE ANY MIMOSA EQUIPMENT IN THE 6 GHz SPECTRUM IN THE UNITED STATES.
- Blocked use of 5.925 GHz through 6.200 GHz by the A5. (This is all I know about ATM)
