+SimGrid (3.0.2) unstable; urgency=low
+
+  XBT:
+  * New module: cunit (my jUnit implementation in ansi C) [MQ]
+    - Test units are placed directly into the library code, they get extracted
+      automatically and placed into the src/testall binary.
+    - Convert most of the XBT tests to this system.
+  * New functions: xbt_dynar_getfirst_as() and xbt_dynar_getlast_as() [MQ]
+  * XML parsing: rewrote parts of flexml to enable multiple xml parsers to
+    live in the same C code. This required to change a little bit the API
+    of surfxml parsing but shouldn't be an issue for end-users. [AL]
+  * 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]
+
+  SURF:
+  * complete rewrote of the KCCFLN05 workstation model. It is now an
+    extension of the classical CLM03 model that gracefully handles
+    failures. This is now the standard model for MSG and GRAS. It doesn't
+    handle parallel tasks yet however. [AL]
+  * Bug fix: Weights were not correctly set in the network part. This may
+    have resulted in incorrect results with simulations where there are
+    more than one flow on a given link. [AL]
+
+  MSG,GRAS:
+  * Bug fix: Processes were started in reverse order, wrt deployment file.
+    WARNING: if your code relies on this bug, please fix it.    [AL]
+  * Bug fix: Add a test in MSG_task_execute to stop whenever a task is
+    being executed on two different locations.                  [AL]
+  * Bug fix: Failures are now better supported thanks to Derrick's tests
+    (there was many failure situations I hadn't thought of and that weren't
+    correctly handled). [AL]
+
+  GRAS:
+  * New! a real RPC mecanism, as it ought to be since too long. [MQ]
+      Exception occuring on server-side are propagated back to client (!).
+      
+    API CHANGE: the callback changed their prototype. Change:
+        int my_handler(gras_socket_t expeditor, void *payload_data) {
+      to:
+        int my_handler(gras_msg_cb_ctx_t ctx  , void *payload_data) {
+          gras_socket_t expeditor=gras_msg_cb_ctx_from(ctx);
+      and you're set.
+  * New! function: gras_msg_handleall to deal with all messages arriving
+      within a given period. 
+
+  AMOK:
+  * Bandwidth module: 
+    - Do not force experiment sizes to be expressed in kb, or it becomes
+      impossible to mesure the latency this way (needs one byte-long tests)
+    WARNING: this changes the amok_bw_* function semantic. [MQ]
+    - Implements the link saturation stuff. [MQ]
+  * Host management module: 
+    New! module factorizing code that we wrote over and over [MQ].

   * Bugfix: there was a problem with the ending of contexts with 
     the pthread backend. It caused some weird deadlock or behavior

+  * Bugfix: get the exceptions raised in the simulator repport where

   MSG:
   * Add additionnal checkings on channel values in communication [AL]

     I'm not sure the potential performance gains justify the coding burden.
