 *** Core library
     + Large number of code refinements and consistency improvements to support
       other developments.

+      start-up performance on larger numbers of processors.
 *** Turbulence modelling
 *** *Updated* thermophysical libraries
     + Now use the more descriptive dictionary input format, e.g. for a single

     + Parallel aware
 *** *New* ptscotch decomposition method
 *** *Updated* particle tracking algorithm
+    + uses non-blocking parallel transfers
+    + does 'minimum-tet' decomposition of face to work with warped faces (snappyHexMesh!)
+    + reuses tracking state in interpolation - improves consistency and speed
 *** *Updated* split cyclics into two separate patches. See doc/changed/splitCyclics.txt
   * *Updated* interpolation (volPointInterpolation) now works without the
     globalPointPatch. Moving mesh cases can now be run non-parallel and
     continued in parallel and reconstructed without any limitation.
 *** *New* compact binary I/O for faces and cells. This speeds up reading/writing meshes in binary.
 *** *Updated* runTimeModifiable

+      dictionaries:

+    + on linux optionally uses inotify instead of time stamps - more efficient for large

     + single integer reduction instead of one reduction per monitored file.
+    + only files that can be re-read are being checked. Drastic reduction of
+      number of files to check.
 * Solvers
   A number of new solvers have been developed for a range of engineering
   applications.  There has been a set of improvements to certain classes of
