+ MSG
+ * Change the prototypes of action replay. Sorry for inconvenience,
+ but this is really more efficient this way.
+ * Kill the braindead MSG_task_refcount_dec() function. I guess nobody
+ ever managed to do anything useful with it.
+
+ SURF
+ * New model for multi-core CPUs. You can now use the core attribute to
+ precise the number of cores of a host. This is a basic model. Every
+ process running on the host receive at most the power provided in
+ the DTD (throughput<=power). Total throughput of process cannot exceed
+ power * num_cores.
+ * New peer tag. This peer tag creates a tiny AS comprising a host and a
+ router linked by an up-link and a down-link (possibly asymmetrical).
+ This kind of pattern allows to easily build last-mile model style platforms.
+ Aggregating such patterns in a rule-based AS is thus the technique of
+ choice for modeling large peer-to-peer/volunteer computing/cloud platforms.
+ * New model for Vivaldi routing. We transformed the Vivaldi network model
+ into a Vivaldi routing model (based on the rule-based model). This allows to
+ combine Vivaldi based latencies with last-mile platforms.

Simix
- * completely rewrote this module to allow parallel execution.
+ * Completely rewrote this module to allow parallel execution.
+ * Introduce a new context factory "raw", highly inspirated from the
+ context factory, but using manually crafted functions in assembly to
+ do the work in an efficient manner.
+ * Allow to change the used context factory at run time, not only at
+ compilation time. Use --cfg=simix/context:raw for maximal speed.
XBT
* Add a new function xbt_dynar_to_array that transforms a dynar into a
due to the change to return type of SD_Simulate. See also:

+ INSTR
+ * New configuration options
+ Options triva/categorized and triva/uncategorized can be used to generate
+ graph configuration files for Triva visualization tool.
+ * Configuration option tracing/platform is renamed to tracing/categorized
+ * XBT logging makes tracing error checks easier, new root log hierarchy: instr
+ * New TRACE_user_link_variable interface:
+ User provides the name of the link and the tracing variable to attach to it
+ * the declaration of tracing categories must be done after the environment creation
+ * simpler tracing interface, just one way to declare categories
+ TRACE_category or TRACE_category_with_color, it is up to you
+ * links in the trace file are again identified by their names
+ * trace contains the full platform hierarchy exactly as declared using the ASes
+ * Options tracing/msg/[task|process]:1 groups the process by hosts
+ for both cases, tasks and processes must have names that are unique during the simulation
+ these options generate traces that are suited to gantt-charts, such as the space-time view of Paje
+ * The experimental option tracing/msg/volume is deprecated
+ its functionality may be reincorporated if needed
