+SimGrid (3.1) unstable; urgency=low
+
+ General:
+ * Port to gcc 4.x
+ There was a stack corruption somewhere, visible only when optimizing
+ with these versions [Vince]
+
+ SIMDAG:
+ * This is a NEW module! SimDAG (SD for short) is a revival of the old SG
+ module that enabled to play with Directed Acyclic Graphs. It is built
+ directly on top of SURF and provides an API rather close to the old
+ SG. Some old codes using SG are currently under rewrite to check that
+ all needful functions are provided. [Christophe Thiery]
