+SimGrid (3.5) unstable; urgency=low
+
+ SimDag
+ * Change the way a task is considered as ready. Instead of removing 
+   dependencies when a task is done, a counter is decreased. This way,
+   it is always possible to reach ancestors thanks to the 
+   SD_taks_get_parents function (even after the end of the simulation.)	   
+ * Change the level of some logs in sd_global from INFO to VERB. The
+   corresponding tests are now less verbose
+ * Change the return type of SD_Simulate from (SD_task_t*) into
+   xbt_dynar_t. This function was in handling a dynar internally and
+   converted it into a NULL terminated array for historical reasons.
+ * Rename the SD_READY (all dependencies are satisfied and task is
+   scheduled) state in SD_RUNNABLE and define a new SD_SCHEDULABLE (all
+   dependencies are satisfied) state. 
+   This prevents a confusion between the notion of "ready to schedule"
+   (SD_SCHEDULABLE) used in DAG scheduling and that of "ready to be
+   simulated" (SD_RUNNABLE) used by the simulation kernel.
+ * Add an example that scheduling a DAX on an heterogeneous platform
+   using a Min-Min strategy
+ * new function SD_dotload(char*) to load a DAG described in dot
+   format. This loader and the corresponding examples require the
+   installation of the graphviz library.
+ 
+ SIMIX
+ * Change the underlying waiting queue in semaphores so that a process
+   can wait on several of them simultaneously (as in waitany).
+ * Fix the way to handle tokens in semaphores so that all access patterns
+   work: {acquire, acquire_timeout, waitany} / {release, release_forever}.
+
+ XBT
+ * New data container: setset (set of sets of elements)
+ * New module: mmalloc (mapped malloc)
+ * New function: xbt_dict_cursor_set_data()
+ * New function: xbt_dynar_sort()
+ * New function: xbt_dynar_is_empty()
+ * New function: xbt_fifo_get_last_item()
+ * Bug fix in xbt_dynar_shrink(): use the right element size
+ * Use library init/fini functions for our initialization.
+   - you can use logs and other feature as soon as you want in your
+     code (even before the xbt_init / MSG_init)
+   - xbt_exit is now a no-op and produce a warning when used.
+
+ GRAS:
+ * New function: gras_msgtype_get_name()
+
+ Build chain: bug fixes and further polishing
+ * Fix the 'make install' target. 
+   No need to use 'make install-simgrid' anymore
+ * Introduce a 'make dist' target compiling a *source* archive
+   'make package' compiles a binary archive (not well tested)
+ * Compile java files only on need
