-* Allowing tracers in global model with nproc > 2.
+* Converting temperature and composition to seismic velocities. The seismic 
+  velocities output can be uploaded to CIG seismic portal for SPECFEM3D 
+  simulation to generate synthetic seismograms.

+* Allowing tracers in global model with nproc > 2 by changing the mesh 
+  slightly.
 
+* The convergence of Stokes solver is controlled by parameter "accuracy" in

+  the norms of div(u), u, and p are no longer dependent on the grid size.

   - A memory bug in visual/project_geoid.c, fixed by Thorsten Becker.
 
-  - Initial temperature for regional model when setting "tic_method=0" or 
-    "tic_method=1" does not match the documented behavior.
+  - Initial temperature "tic_method=0" for regional model applied sinusoidal 
+    perturbations to 0th processor only.

+  - Initial temperature "tic_method=1" for regional model generated a top 
+    thermal boundary layer 25x older than specfied by "half_space_age".
 
   - Compiling with both HDF5 and Exchanger support will crash Cookbook 9
