 This is the README file for Subsurface 4.0.
 
-After the release of Subsurface 3.1 we merged the Qt branch into
-master and started developing the Qt port of Subsurface in the master
-branch. At this stage the Qt version has by and large reached
-functional parity with version 3.1; two notable features are missing:

+After the release of Subsurface 3.1 the Subsurface developer team
+decided to make a major change in the development direction of the
+project. We switched to Qt as our UI toolkit and slowly, step by step
+replaced all the Gtk with corresponding Qt code.
+
+This caused lots of changes, from adding C++ code, switching build
+systems to use qmake, to refactoring the tightly intervoven UI and
+logic code that we had up until 3.1. The vast majority of this work
+was done by just a handful of people with Tomaz Canabrava carrying the
+biggest part of the load. As we had hoped, the switch to Qt brought us
+many new active developers and the Qt community has been extremely
+helpful supporting us when we ran into trouble.
