Most important changes:
* surf and simix modules reworked for simplification.
It lays the ground for future extensions and improvements of SimGrid
- * SMPI was further improved, altrough not ready for production use yet.
+ * SMPI was further improved, although not ready for production use yet.
On the way, we gained a bit more than 5% on the classical master/slave
example. More to come on this in future releases.
