I think it has!
I downloaded it on Friday- 1200 ZD and 4 R510 APs. Left the APs disconnected after failing to update their firmware. I rolled back ok, but wouldn’t recommend anyone else try it.
Late Friday I received an email from Ruckus OPs:-
“We are contacting you because you downloaded the RUCKUS ZoneDirector 10.4.1.0.254 (GA Refresh3) software image and/or MIBs file on 8-9 April 2021 from the RUCKUS Support Portal.
The RUCKUS ZoneDirector 10.4.1.0.254 (GA Refresh3) software release has some unresolved bugs that might cause issues if the release is deployed in your network. RUCKUS Engineering will release a software update for them in the first week of May 2021.
At this time, we recommend you do not install the RUCKUS ZoneDirector 10.4.1.0.254 (GA Refresh3) software in your network. If you have already installed it, please roll back to your previously-installed version.
