   * Fix a vicious bug in the TCP buffering mecanism which leaded to message
     loss when they were small enough to fit into the buffer and sent quickly

+    enough so that they can all get received in one shoot.   
+  * gras_datadesc_by_name and gras_msgtype_by_name: now raise an exception
+    if not found. Use the *_or_null() variant for the old semantic.
+  * In gras_msg_handle, do not discard messages without callback.
+    They are probably messages to be explicitly awaited later (ie, proofs of
+    mis-synchronization in userland since they are sent before being awaited)
+    No big deal usually.
+  * gras_socket_meas_send/recv: semantic changed!
+    The numerical arguments used to be (1) the total amount of data to send
+    and (2) msg_size. This was changed to (1) msg_size and (2) amount of
+    messages. This was need for the fool willing to send more than MAXINT
+    bytes on quite fat pipes.

   AMOK:
   * Do really rename the hostmanagement module to peermanagement. [Mt]
     Ie, rename functions from amok_hm_* to amok_pm_*. This breaks the API,
     but this is rather new and this was documented in the module
     documentation (poor excuses, I admit)
+  * Bandwidth measurement semantic changed! This follows the changes to
+    gras_socket_meas_send/recv explained above.

   SURF:
   * The KCCFLN05 workstation model now handles parallel tasks. It is the
     model for SIMDAG. [Christophe Thiery]
+  * Bug fix in the maxmin solver: Some values were close to 0 instead of
+    equal to 0, which caused some bad behaviors in
+    saturated_constraint_set_update. I now use a threshold mechanism like in
+    surf. [AL]
 
   XBT:
   * When running manually src/testall, you select specific units [Mt]
     testall is the result of our cunit mecanism, and should replace all
     the scripty thingy around since bash don't run easily on billware.
 
+  * A mallocator system has been added. [Christophe Thiery]
+    Mallocators allow you to recycle your unused objects instead of freeing them
+    and allocating new ones.
