I went from 4b2 to 4b3 some days ago, no issues to upgrade.
Spent some weeks playing with ROS 5RC11, 5RC12 and now settle on 5.0.
My system is small, e.g. a 433UAH, a pair of 411ARs, 3 old WRAP X86, all loaded with ROS5.0 now. Around 70 CPEs (NS2 Loco & Bullet 2). There is 3 XR9 for NLOS path.
* Any card that run as client-bridge (R52Hn, XR9, R52n), after this double upgrade to 4B3 x ROS 5.0 missed the speed/signals levels at the labels. On the other side, if I create a link between any UBNT client and AP still showing signals levels (tx/rx), connection speed & etc. At the MT devices, does not matter if mastering is snmp or routeros. Just data speed shows up.
* Torch avialable at mouse over link lables + right click does not run.
* I'm using Dude to collect & graph some data volume info, as measured by "bytes" field on queue tree. Those queues are common low priority (priority=8) channels I set to those traffic which customers does not realize about, like Windows Update, several anti-virus update, adobe update, etc ... and Youtube/4shared. Each uses pcq and a max limit so customers share those channels. I expected a monthly basis graph, reseting all counters after 30 days by myself - but - most are reseting when the volume reaches 4.1 ... 4.3 GBytes. I guess this is not Dude related but ROS. Anyway.
PS: not Dude but 5.0 winbox ... torch on simple queues (mouse over a simple queue line) is not running too, the source address filter field on torch is not being filled with simple queue target address, as used to be on ros 4.17.
