This release was brought to you by Albert Astals Cid, Andre Heinecke, Ilia Kats, Jordan Abrahams-Whitehead, Khaled Hosny, Sune Vuorela and everyone else that filed bugs or helped with code reviews :)

Testing, patches and bug reports welcome.

The Qt signature tests will fail if you have a new enough gpgme but an old gpg (i'm looking at you Achlnux), disable the gpgme backend or apply https://paste.debian.net/downloadh/aa079683 and a similar one for qt5.

Cheers,
  Albert

P.S: Yes, I'm aware I'm a bit behind in following up some MRs, more reviewers are always welcome
