 v2.0.0 (UNRELEASED)
 ===================
 
-Feature release.
+Mopidy 2.0 is here!
+
+Since the release of 1.1, we've closed or merged approximately 80 issues and
+pull requests through about 350 commits by 14 extraordinary people, including
+10 newcomers. That's about the same amount of issues and commits as between 1.0
+and 1.1. The number of contributors is a bit lower, but we didn't have a real
+life sprint in this development cycle. Thanks to :ref:`everyone <authors>` who
+has :ref:`contributed <contributing>`!
+
+With the release of Mopidy 1.0 we promised that any extension working with
+Mopidy 1.0 should continue working with all Mopidy 1.x releases. Mopidy 2.0 is
+quite a friendly major release, and will only break a single extension that we
+know of: Mopidy-Spotify. To ensure that everything keeps on working, please
+upgrade to Mopidy 2.0 and Mopidy-Spotify 3.0 at the same time.
+
+No deprecated functionality has been removed in Mopidy 2.0.
+
+The major features of Mopidy 2.0 are:
+
+- Gapless playback has been mostly implemented. It works as long as you don't
+  change tracks in the middle of a track or use previous and next. In a future
+  release previous and next will also become gapless. It is now quite easy to
+  have Mopidy streaming audio over the network using Icecast. See the updated
+  :ref:`streaming` docs for details of how to set it up and workarounds for the
+  remaining issues.
+
+- Mopidy has upgraded from GStreamer 0.10 to 1.x. This has been on our backlog
+  for more than three years. With this upgrade we're ridding ourselves with
+  years of GStreamer bugs that have been fixed in newer releases, we can get
+  into Debian testing again, and we've removed the last major roadblock for
+  running Mopidy on Python 3.
 
 Dependencies
 ------------
 
 - Mopidy now requires GStreamer >= 1.2.3, as we've finally ported from
-  GStreamer 0.10.
+  GStreamer 0.10. Since we're requiring a new major version of our major
+  dependency, we're upping the major version of Mopidy too. (Fixes:
+  :issue:`225`)
