Packages for individual platforms and distros will follow shortly.

For your convenience, these are the ubuntu/debian packages required to build the source:

$ sudo apt-get build-dep darktable && sudo apt-get install libgtk-3-dev libpugixml-dev libcolord-gtk-dev libosmgpsmap-1.0-0-dev libcups2-dev

And the preliminary changelog can be found below.

When updating from the currently stable 1.6.x series, please bear in mind that your edits will be preserved during this process, but it will not be possible to downgrade from 2.0 to 1.6.x any more. Be careful if you need darktable for production work!
