I've just upgraded my NAS from 7.3.2.

After rebooting one of my Docker stacks managed by Compose Manager Plus was broken because the ID of the network "br0" had changed. Not sure if normal or not.

Compose down + compose up fixed the problem.

Not sure if related but I've lost control over one of my PWM fans...

EDIT: Probably nothing to do with that update, seems to be hardware related.

Is it new for you to have stacks on br0? It's been that way for ages for me, br0 is created fresh each boot so has a new id, need to make your own macvlan/ipvlan network to avoid that

No it is not new and it's the first time I have that issue.

Coming from 7.3.3.

No issues so far.

VM (Win 11 with gpu also and pci-e usb card passthrough) working well.

My server had updated from 7.3.2 to 7.3.3 recently, just the reboot was still pending.

I didn't do it, I rebooted the server first to finish the first reboot before doing the second.

But should it have worked to immediately do the second update and reboot then?

Just wondering.
