+ - Add two new log appenders : rollfile and splitfile. Patch by Fabien Chaix.
+ Build System
+ * Tracing is now always enabled (no way to turn it out)
+ * Move headers around to sort them out on installed systems:
+ - instr/instr.h -> simgrid/instr.h
+ - instr/jedule/* -> simgrid/jedule
+ - simdag/datatypes.h was removed
+ - simdag/simdag.h -> simgrid/simdag.h
+ - msg/datatypes.h was removed
+ - msg/msg.h -> simgrid/msg.h
+
+ MC
+ * The model checker now runs as a separate process.
+ * The model checker runs must now be launched with the new simgrid-mc program.
+ * Record/Replay: the MC can display a textual representation of a path in the
+ execution graph. It can then be replayed outside of the model checker.
