+ - Remove option 'model-check/sparse-checkpoint': Checkpoints are now
+ always sparse. That's an immense gain in memory, and can even be
+ faster because of cache effects. So there is no need to clutter the
+ code to allow the user to go for the unefficient mode.
+
+Network models:
+ - Remove the lagrange-based models (Reno/Reno2/Vegas). The regular
+ models proved to be more accurate than these old experiments.
+
+Python:
+ - Simgrid can now hopefully be installed with pip.
