   The "Simplicity does not preceed complexity, but follows it" release.
 
   Models:
+  * Change the correction factors used in LMM model, according to
+    the lastest experiments described in INRIA RR-7821. 
+    Accuracy should be improved this way.
+    (TODO: this is not true in the code, yet)
   * Use the partial invalidation optimization by default for the
     network too. Should produce the exact same results, only faster.
   * Major cleanup in surf to merge models and split some optimization

   * The CLM03 workstation model were dropped for simplicity because it
     used the deprecated CM02 network model. Use default instead.
   * Rename the TCP_gamma configuration option to network/TCP_gamma
+  * Rename the coordinates configuration option to
+    network/coordinates, and document it
   * Use now crosstraffic keyword instead of the terribly missleading 
-    fullduplex keyword. Use --cfg=network/crosstraffic:1. This is
-    activated by default now in the current default model.

+    fullduplex keyword. It is activated by default now in the current

+  * Ongoing refactoring the model parsing to make XML files optional
+    (more work is needed here to fully achieve this goal)

+  Simix:
+  * Stabilize the parallel execution mode of user contexts
+  * Introduce configuration variables to control parallel execution:
+    - contexts/synchro: Synchronization mode to use when running
+      contexts in parallel (either futex, posix or busy_wait)
+    - contexts/parallel_threshold: Minimal number of user contexts

   * Performance boost by using a swag internally to compute the set of
     tasks that are finished and should constitute the return value of
