* Add an experimental interface to manipulate VMs. They are mainly
process groups with very few intrinsic semantic, but they should
allow you to build the semantic you want easily.
+ * New function: MSG_host_set_property_value()
+ * Deprecate functions MSG_global_init() / MSG_global_init_args()
+ Please use MSG_init() instead. (reducing the amount of entry
+ points in the library helps us).
+ * Make it impossible to link against the wrong version of the lib
Simix:
* Bug fixes around the resource failures: don't let the processes
survive the host they are running onto
SimDag:

+ * New types of typed tasks. SD_TASK_COMP_PAR_AMDAHL represents a
parallel task whose initial work is distributed among host according
to the Amdahl's law. Such tasks are created with a parameter alpha
- that corresponds to the non-parallelizable part of the computation.

- Before calling SD_task_schedulel or SD_task_schedulev, the
- SD_task_distribute_comp_amdahl function has to be called with the
- desired number of workstations. The filling of computation_amount and

+ SD_TASK_COMM_PAR_MXN_1D_BLOCK represents a complex data redistribution

+ These tasks can be scheduled with SD_task_schedulel or SD_task_schedulev.

* New function SD_workstation_dump to display various information
