+BornAgain-1.12.0, released 2018.05.30
+  > No API changes
+  > Summary:
+    1) First implementation of specular simulation in GUI.
+    2) DepthProbeSimulation for experiment preparation.
+    3) Documentation: remaining part of website has been migrated to Hugo website.
+    4) Beta version of 3d sample view.
+    5) Interference function for finite 2d lattices (core + GUI).
+    6) Interference function for a 2d superlattice.
+    7) Fitting: first refactoring to bring it closer to generic Python fit interfaces.
+    8) Numerous other bugfixes.
