 SimGrid (3.3-cvs) unstable; urgency=low
 
- OVERALL CHANGES:
+ Introduce the SIMIX module: factorize code between MSG and GRAS.
+   [Bruno Donassolo]
+  Until now, GRAS were using MSG as an interface to SURF. It was
+   quite difficult because both interface have several differences
+   (MSG channels vs GRAS sockets were the most notable point).
+   
+  This also opens the gate to SMPI (which should occur soon) and speed
+   up simulations by to 40% (even if it were not the main goal).
+  
+ ************************************** 
+ *DO NOT MIX 3.2 RESULTS WITH 3.3 ONES* Simix may changes simulations!
+ **************************************
+   The point is that events occuring at the exact same timestamp are
+    not scheduled in the same order with the old and new version. This
+    may be enough to completely change the execution of simulations in
+    some cases. Sorry for the inconvenience.
+
+ GRAS:
+  * Convert the PIDs from long int to int to match the MSG ones (and
+    linux ones too)
+
+ XBT:
   * Make the backtrace of exceptions more human readable [Mt]
