 ===================================================
 
 * IMPROVEMENTS and ENHANCEMENTS: 
-  - Decoupled Models: An h-adaptive model using a mpfa l-method was added
-    that simulates 2p and 2p2c flow on irregular grids in two dimensions.
+  - Two new fully implicit models dedicated to simulate compositional
+    (non-isothermal) CO2-brine systems have been added, together with 
+    corresponding components and a fluid system. See test/boxmodels/co2(ni) 
+    for details. These tests also illustrate the usage of element and vertex 
+    parameters as well as boundary ids provided by DGF files for setting 
+    permeability and porosity as well as boundary conditions.

+  - Decoupled Models: An h-adaptive model using an MPFA L-method was added

+    See test/decoupled/2p(2c) for details.
+
+  - The Stokes models are capable of simulating the full Navier-Stokes 
+    equations for momentum transport. See test/freeflow/navierstokes 
+    for details.
 
 * IMMEDIATE INTERFACE CHANGES not allowing a deprecation period: 
   - Implicit models: TwoPIndices, TwoPNIIndices, and RichardsIndices additionally
