   The "Simplicity does not preceed complexity, but follows it" release.
 
   Models:
+  * We can specify the smpi latency/bandwidth factor with command line
+    add --cfg=smpi/bw_factor:"threshold0:value0;...;thresholdN:valueN"
+    or add --cfg=smpi/lat_factor:"threshold0:value0;...;thresholdN:valueN"
+    You can also use the "config tag" from platform file by adding this line
+    <prop id="smpi/bw_factor" value="threshold0:value0;...;thresholdN:valueN"></prop>
+    (see "example/platforms/tag_config.xml" to use "config tag").
+    Note that the command line supersedes the platform file configuration.
+  * 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

     Incompatible combinations should err at initialization. See
     --help-models for the list of all models and optimization modes.
+  * 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.

+  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
