+
+  XBT:
+  * New! Exception handling with setjmp or such (code from OSSP ex) [MQ]
+    This deprecates the xbt_error_t mecanisms. 
+    It modifies (simplifies) all XBT and GRAS API.
+    MSG API keeps unchanged (exceptions raised by XBT are catched from 
+     within MSG and masked with existing error handling facilities)
+
+  SURF:
+  * New! Add a FATPIPE model. [AL]
+  * New! Add a parallel task model. [AL]
+  * New! Add automatically a loopback interface (in the default
+    network model) if none was precised.
 
   MSG
-  * Implement MSG_get_msgload [MQ]
+  * Bugfix: MSG_process_resume now works with the current running process. 
+    [AL]
+  * New! Add MSG_parallel_task_create and MSG_parallel_task_execute. [AL]
+  * Modification of MSG_task_get_compute_duration. Once a task has been
+    processed, the value returned by this function is now equal to 0. [AL]
+  * New! Add double MSG_task_get_remaining_computation(m_task_t task) and
+    MSG_error_t MSG_task_cancel(m_task_t task). Add a state
+    (MSG_TASK_CANCELLED) to MSG_error_t corresponding to the cancelation
+    of a m_task. For now, MSG_task_cancel only works with computation
+    tasks. [AL]
+  * New! Add double MSG_get_host_speed(m_host_t h) that returns the speed
+    of the processor (in Mflop/s) regardless of the current load on the
+    machine. [AL]

+  XBT
+  * Steal some nice code to GNU pth to fix context detection and usage [AL]
+  * Cleanup in the xbt_config API; add configuration callbacks. [MQ]
+  * Cleanup in the initialization API: the unused "defaultlog" is dead. [MQ]
 
   SURF
   * Bugfix: Allow absolute paths for platform description files [MQ]
+  * Bugfix: do free the variables after use. Leads to drastic performance 
+    improvement [AL] 
+  * Implement max_duration (ie, timeouts) on resources [AL]
+
+  MSG
+  * Implement MSG_config to configure MSG at runtime. xbt_cfg test on a real
+    case ;) [MQ]
+  * Implement MSG_channel_select_from() to help GRAS now that SURF provide
+    the needed support (timeouts) [AL]
 
   GRAS (new features)
+  * Implement measurement sockets. You can now get the bandwidth between two
+    hosts thanks to AMOK (see below). [MQ]
   * gras_datadesc_dynar() builds a dynar type descriptor, allowing to send
     dynar over the network (yeah) [MQ]
   * Real (even if simplistic) implementation of gras_os_myname() on RL [MQ]
+  * simple/static token-ring example. [Alexandre Colucci and MQ]
+  * Use MSG_channel_select_from() and remove the *slow* hack we had to put
+    in place before [MQ]
