FYI FWIW that I uploaded Andy's software and here are some random comments - TL;DR is to echo what others said, it was uneventful and all seems to be working well.
I use Edge on a Win11 desktop with the camera on the same LAN, so I opted to just "do" the upgrade rather than reset to factory defaults ... and the two step process (there are two .Bin's) appeared to work fine. Note that while the latest "official" release has "Empiretech" at the start of the filename, this test firmware has "General" instead - Andy (who is super responsive!) said that's a non-issue.
I didn't notice any visual difference in the images (nor would I expect any) but I'll check tonight in more challenging low-light just to be sure.
Using Edge, I still get the annoying
"WebSocketServer23450.exe" popup before login ... and then the
"To use this function, please download and install the plug-in" at the bottom once I'm logged in. As mentioned, be nice to have some method of disabling that since I seem to be able to do most everything with out it. Notable exception is the ability to download multiple files at once which isn't a show-stopper (UPDATE: OOOPS ... this does work!)
BTW, when downloading a single video file, there still seems to be some goofy limit of 10Mbps as it runs right at that speed ... even though the switch/cable is GigE (tested!) to the camera which is 100Mbps.
Menu's look very similar ... there's a new "Maintenance Center" which consolidates some things from other areas (logging, updates, etc.) and it has a new
"One-click diagnostic" which checks some network stuff and
"Checks if the power is being normally supplied" - the later had some errors back in February, but I think those are software vestiges rather than actual events that happened.
Clicking on System Info, I saw the following before/after - BOLDING shows the changes after the upgrade:

Everything seems to be working same as before. TBD on the tracking (which I don't use much) as so far, it has only (correctly) flagged me walking outside to get the trash bin.
Good timing since a neighbor posted this picture yesterday on our private FB group. Bears are very unusual in our neighborhood - LOL if it flags/captures one! ;-)
