6. Multi-room: After ungrouping, metadata no longer syncs to previously grouped (child) speakers.
7. Gapless Player: Fixed a near track end race condition that could trigger overlapping/simultaneous playback.
8. Local Files: Fixed an issue where the app progress bar reached the end before playback finished.
9. TuneIn: Now consistently selects the highest available stream quality.
10. Amazon Music: Fixed unexpected stops when using Amazon Music Cast.

Just curious, why the need to disable LMS by default? It has never interfered with my using the WiiM or Qobuz Connect apps. I do understand that it is still available, but am just interested in the reason behind the change. And, BTW, it has been Lyrion Music Server for some time now. Logitech dropped their support some time ago.

It isn't LMS or even Lyrion Music Server... It's a version of Squeezelite, a LMS compatible player.

I understand the difference -- I run the LMS (server) on a separate RPi and have the Squeezelite option turned on for all my WiiM players plus another RPi/PcP player. It was the above post from WiiM that referred to LMS -- its not unusual for people to use the LMS/Squeezelite terms interchangeably.

Yes. This has been reported several times but @WiiM Team insist on calling it "Logitech Media Server" although it is not a server and not Logitech

Don’t know but perhaps some people like the ability to disable a feature they don’t use - similar was implemented for Roon recently and there was even a request a while back to turn off DLNA player support…

Update received, thank you. I'm curious how the new 12v trigger feature works - can someone explain that to me please?
