+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

+SimGrid (3.4.1) stable; urgency=low
+
+ The "Polishing easter eggs is probably a good idea" release.
+ This is a bug fixes release only.
+
+
+ Java Bindings
+ * Fix a bug preventing the tasks from begin garbage collected.
+
+ MSG
+ * Fix a bug occuring when a host involved in a communication fails.
+ This was not detected properly by the other peer involved in the
+ communication. Now, it's reported as a network error.
+
+ SimDag
+ * Warn the user about loop dependencies in data flow of DAX files
+ * Obey the control-flow dependencies of DAX files
+
+ Cmake
+ * Add option "enable_smpi" allowing to not compile SMPI.
+ Probably useful for the (Mac) users experiencing a build error here
+ * Improve the detection of lua5.1 and ruby1.8

+SimGrid (3.4) stable; urgency=low
The "Easter in Cargese" release. Also known as (major changes):
* Add a SD_task_set_name() function
* Fix SD_task_unschedule() on typed tasks
* Fix SD_task_get_execution_time() to return seconds, not flop*sec
+ * In DAX loader, accept useless 'level' attributes to <job> since
+ LIGO DAGs have them (seem to be to ease graphical representation).
MSG:
* Add an example masterslave_mailbox.c using send/receive and not
the deprecated put/get interface.
and call MSG_action_trace_run(NULL)
You can still have one merged file for all processes.
- Fix implementation of collective operations
+ * Allow task_execute() on 0-sized tasks (closes #10063)
SMPI:
* This is the first release of SimGrid where SMPI is not considered
beta anymore (even if some corners should still be improved)
maestro.
- Merge context_start into context_new for sake of simplicity
SURF:
+ * Add a Vivaldi network model, coded live during SUD'10 ;)
* Rename configuration variables to start a hierarchy:
o cpu_model -> cpu/model
o network_model -> network/model
* Added code coverage tests.
Our coverage is still improvable, but at least we see it on cdash.
