- The "SimGrid makes psssshiiiit and jumps into the cloud" release.
+ SMPI:
+ * Now works on Windows too!

 
 

- Cmake:
- * Remove option custom_flags. Now use environment variables CFLAGS
-   and LDFLAGS.
- * Enable tracing by default. This modules rocks you should use it.
- * Use default cmake things to detect lua instead of home grown ones.

  * Add an experimental interface to manipulate VMs. They are mainly
    process groups with very few intrinsic semantic, but they should
    allow you to build the semantic you want easily.

- * Deprecate functions MSG_global_init() / MSG_global_init_args()

- * Make it impossible to link against the wrong version of the lib

- * Add an interface to execute cleanup functions when a process is killed,

  SimDag:

+ * Bug fix for when SD_Simulate is called with a positive value: be careful
+   when comparing doubles. Sometimes they are different for non significant
+   digits only.

  * New types of typed tasks. SD_TASK_COMP_PAR_AMDAHL represents a
    parallel task whose initial work is distributed among host according
    to the Amdahl's law. Such tasks are created with a parameter alpha

+ * Implement the exchange of non-contiguous data.
+   [Khalid Hasanov & Jean-Noel Quintin] Thanks for the patch, guys.
+ * Correct behavior of smpi/sender_gap and set its default value to 0
+ * Add option to asynchronously send small messages to allow better
+   simulation of pt2pt communications. --cfg=smpi/async_small_threshold:value
+   specifies the size in bytes under which messages will be asynchronously sent.
+ * Add support of MPI_Iprobe, MPI_Probe, MPI_Testall, MPI_Wtick functions
+ * SMPI now handles more MPI specific values in input. Closes [#14389] and [#14388]
+
+ SimGrid:
+ * New C interface to define a platform: XML is now optional.
+   For more info, please check include/simgrid/platf.h.
+ * New interface to define random platforms from the C:
+   For more info, please check include/simgrid/platf_generator.h and
+   examples/msg/masterslave/masterslave_platfgen.c
+ * Export a sg_cmdline dynar containing all the arguments we got from
+   the command line.
+
+ TRACE:
+ * Two new tracing options for adding comments to trace file so you
+   can track your experiments (see --help-tracing for details).
+ * New option to generate a impoverished trace file (--cfg=tracing/basic:1)
+ * Adding the SimGrid version that generated the trace file as a comment.
+ * Instrumenting other MSG functions (MSG_task_isend_with_matching and MSG_task_dsend)
+ * Fix to avoid key clashes on Paje links
+ * Other minor fixes related to the Paje specification

  XBT:
  * Functions xbt_dict_hash() and xbt_dict_hash_ext() are made public,
    and renamed to xbt_str_hash() and xbt_str_hash_ext().
  * New function: xbt_os_timer_resume() to restart a timer w/o resetting it.
