Nothing really of importance. We are always tweaking it here and there.
An example of performance improvement:
WINS/NetBIOS queries resolve after DNS queries now. The result is a tiny speed up for DNS lookups. Nothing anybody will notice, but given that you rarely resolve local SMB mounts and you usually do resolve Roon/TIDAL/Qobuz DNS addresses, this is the right thing to do for a slightly snappier experience. VERY VERY slightly snappier.
An example of a bug fix:
On a machine that was all properly set up and booted properly,
- if you removed link power from the end of an ethernet cable plugged into a switch,
- but left it plugged into the Roon OS machine,
- in some not easily predictable circumstances,
the console failed to update its text to show that there was no network plugged in
Once again, not worthy of note.
