       factorize some code developped over and over in the examples and AMOK.
     It has still to be documented and used (only amok/peermanagement is
       converted for now).
+  * 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 excuse, I admit)
-
-  Documentation update:
-  * New FAQ: "Valgrind spits tons of errors!" [Mt]
-  * GRAS tutorial [Mt]
-    It contains:
-     - an introduction to the framework and to the used communication model
-     - an initiatic tour introducing the most proheminent features:
-       # Lesson 0: Installing GRAS
-       # Lesson 1: Setting up your own project
-       # Lesson 2: Exchanging simple messages
-       # Lesson 3: Passing arguments to the processes (in SG)
-       # Lesson 4: Attaching callbacks to messages
-       # Lesson 5: Using globals in processes
-       # Lesson 6: Logging informations properly
-       # Lesson 7: Using internal timers
-       # Lesson 8: Handling errors through exceptions
-       More a due, of course. At least the one explaining how to add data
-       into messages. In the meanwhile, you can check the examples which are
-       still here.

+  * Bandwidth measurement semantic changed! This follows the changes to
+    gras_socket_meas_send/recv explained above.

   SIMDAG:
   * A sequential mode has been added to the workstations. When a workstation
     is in sequential mode, it can execute only one task, and the other tasks

   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.
