 SimGrid (3.7) NOT RELEASED; urgency=low
 
-  The "Simplicity does not preceed complexity, but follows it" release.
+  The "sprint cleanups (before spring)" 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

   * Use now crosstraffic keyword instead of the terribly missleading 
     fullduplex keyword. It is activated by default now in the current
     default model, use --cfg=network/crosstraffic:0 to turn it off.
+  * Experimental: new configuration option --cfg=surf/nthreads:N to run
+    analytical models in parallel with N threads (default is 1).
+  * Ongoing refactoring the model parsing to make XML files optional
+    (more work is needed here to fully achieve this goal)
