+SimGrid (3.1.1) unstable; urgency=low
+
+ GRAS:
+ * New module mecanism where user code can use per process globals [Mt]
+ This is similar to gras_userdata_*() functions, but for libraries. It
+ 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 excuses, I admit)
+ * 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
+ are waiting in a FIFO. [Christophe Thiery]
+
+ 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]
