+  * Documentation of the tracing functions.
+  * Performance gains when tracing categorized/uncategorized resource

+    of TRACE_sd_set_task_category. They only work if ENABLE_TRACING is ON.
+  * Bugfix for graphicator, routes not correctly obtained, memory leaks
+  * Examples for link user variables added (see at examples/msg/tracing/)
+  * Deprecated function TRACE_msg_set_process_category completely removed

+  Lua:
+  * Improve the API of Lua MSG bindings, using the Lua spirit.
+  * Each simulated process now lives in its own Lua world (globals are
+    automatically duplicated). It helps writing simulators. This is also the
