Hi Till,

thank you for the news!

A note regarding the news:

Ad GTK temp queues and cups-browsed usefulness - the feature is 
implemented only for GTK3+, so apps with older GTKs still needs a 
permanent queue for local printer (f.e. gimp and thunderbird). 
Additionally, Brian Potkin from Debian found out some problems with 
ipp-usb supported devices [1], does it work in GTK3 apps in Ubuntu?

And some apps (f.e. firefox) started to use their own print dialog 
without temp queue support [2], so cups-browsed is still needed for them 
and Qt...

Additionally, cups-browsed still is the only one automatic way how to 
get printers from non-local server, until I'll get a time to get my 
hands on CUPS profiles, together with load balancing, clustering and 
high availability features of cups-browsed.

Best regards,
