Dune 1.2.0

On behalf of the dune team, I'm pleased to announce the release of Dune 1.2.0. This release contains many new goodies which I will not describe here. This is because Etienne Millon has prepared a blog post for this release: https://tarides.com/2018-09-06-dune-1-2-0.html

I'd also like to personally thank him for all work he's done to make this release so great.

As usual, the change log is replicated below for your convenience.

Happy hacking!
