• DNS-SD advertising of the USB-over-IPP printer for easy recovery by CUPS and cups-browsed

• Allow identifying the desired printer by USB Bus and Device
• Reasonable USB timeouts (a few seconds instead of 6 hours)

Ubuntu 14.04 + license headers

This release is slightly ahead of what will ship in Ubuntu 14.04. Compared to that release there have been no code changes, only the license headers have been added.

Prior beta releases included in unstable beta versions of Ubuntu 14.04 were not tagged but should be of no historical interest.
