 SimGrid (3.27.1) NOT RELEASED YET (v3.28 expected June 21. 2021, 03:32 UTC)
 
 New features:
+ - C++ platform interface: Users can now describe their platform directly in C++.
+   This provides greatly flexibility and performance improvement for complex
+   platforms. Main features:
+     - Fat-Tree/DragonFly/Torus composing: allows you to create clusters of
+       "zones", instead of single hosts. This feature enables the description
+       of clusters with complex hosts, composed of several CPUs, GPUs, etc.
+     - StarZone: new zone with a Star-like topology. The routes are defined
+       as a set of links used to communicate from node to everybody (node<->ALL).
+     - Split-Duplex links: auxiliary method to create split-duplex links in
+       the platform, easing its utilisation. It automatically creates both UP
+       and DOWN links (similarly as done in XML).
+     - Please refer to the documentation and the examples included:
+       e.g. examples/cpp/clusters-multicpu/ and examples/platforms/*.cpp.
  - New plugin: Producer-Consumer with monitor. Just requires to include the
    include/simgrid/plugins/ProducerConsumer.hpp header to be used. See the
    associated example (examples/cpp/plugin-prodcons).

     - fix behaviour, as maximum iteration count could be ignored
     - add SMPI_SAMPLE_LOCAL_TAG and SMPI_SAMPLE_GLOBAL_TAG macros, to allow user to
       use sampling when the same kernel is called with a different set of parameters
       which have an impact on the timing.
-  - realloc is now intercepted, to be coherent, as malloc/calloc/free were already.
-    It should now work with smpi/auto-shared-malloc-thresh.
-  - Improve error handling and reporting in multiple places
-  - Improve correctness checks on the MPI code.(MPI_Op and MPI_Datatype
