Nope. Just common decency, a bit of respect, and perhaps some appreciation and gratitude.
Steering to on-topic:
Concerning the UPnP plugin, if you would search and read this thread a bit better, you will find plenty of information why this plugin is problematic for many users, and why development is on a hold.
Also understand that this is only an optional plugin, it's not an integrated part of MusicBee itself.
Anybody with coding talent and interest has been welcomed to help working on the plugin to possibly improve it.
Nobody has offered to help with it as yet.
