 SimGrid (3.6) unstable; urgency=low
 
+ 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.
+
+ XBT
+ * Add a new function xbt_dynar_to_array that transforms a dynar into a
+   NULL-terminated array. This may solve backward compatibility issues
+   due to the change to return type of SD_Simulate. See also:
+   http://lists.gforge.inria.fr/pipermail/simgrid-user/2010-December/002206.html
+
+ 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
