This could be a beta firmware. Maybe not.


Which constant are you referring to? Some users constantly complaining about not getting an announced firmware as if they had an immediate right to? Or other users constantly complaining about firmware versions being pushed before there is an announcement on the forum?

Never complained about any delay or about the delivery queue, you know.
I'm just seeing that it's several times, during late months, some updates were just not announced even if these were actually already in distribution.
Just this.

Which would you rather have?? A speedy bugfix or fanfare over a one-line changelog posting??

I'm really surprised to see simultaneous output added to the Ultra beta. Has anyone tested it yet?

My Wiim Ultra received firmware 5.2.810346, build date 20260310. Nothing to read in forum about it

Just confirmed it with the team that this is a beta release which has some TIDAL playback stability improvements. We don't currently publish release notes for specific beta builds, just the firmware threads when the release is live, and beta announcements when one it launching. But maybe we will look into dedicated threads to announce beta firmware releases.
