+ * New module: sparse graph structure with basic algorithms (this is work
+ in progress and the API is not considered to be frozen yet). [AL]
+ * Display more information on backtraces: source line & function names are
+ now displayed just like valgrind does (rely on addr2line tool) [MQ]
+ * New function: xbt_backtrace_display(). Sweet while debuging [MQ]
+ * Reworked a little bit some #include statements to load only required
+ headers. Some user code that relied on SimGrid to include stdlib or
+ stdio may need to include it by themselves. [AL]
+ * Fixed xbt/log.h. A missing SG_BEGIN_DECL prevented compilation with
+ g++. [AL]
