    Comm::set_payload_size() to change the size of the simulated data.
  - New function: Engine::flatify_platform(), to get a fully detailed vision of the
    configured platform.

+ - Full simDAG integration: Activity::start() actually starts only when all dependencies
+   are fullfiled. If it cannot be started right away, it will start as soon as it becomes
+   possible.
+ - Allow to set a concurrency limit on disks and hosts, as it was already the case for links.
+ - Rename Link::get_usage() to Link::get_load() for consistency with Host::
+
+New plugin: Operation
+ - Operations are designed to represent workflows, i.e, graphs of repeatable Activities.
+ - Documentation: https://simgrid.frama.io/simgrid/Plugins.html#operation
+ - Examples: examples/cpp/operation-*

+New plugin: Battery
+ - Enable the management of batteries on hosts.

- - optimize an internal datastructure, leading to a potentially big
-   performance gain (in particular with many detached comms)

 MPI:
  - New option smpi/barrier-collectives to add a barrier to some collectives
    to detect dangerous code that /may/ work on some MPI implems.
+ - New function SMPI_app_instance_start() to easily start a MPI instance in your S4U simulation.
 
 Models:
  - Write the section of the manual about models, at least.

    with the default host model, as it should.
  - Rename option "surf/precision" to "precision/timing" for clarity.
  - Rename option "maxmin/precision" to "precision/work-amount" for clarity.
+ - New function: Engine::flatify_platform() to debug your platform.
 
 sthread:
  - Implement pthread_join in MC mode.
+ - Implement semaphore functions in sthread.
+ - Add an intricated way to verify the access to non-reentrant data structures
+   It requires code annotation, as shown in examples/sthread/stdobject/stdobject.cpp
+
+Model checking:
+ - Synchronize the MBI tests with upstream.
+ - Show the full actor bactraces when replaying a MC trace (with model-check/replay)
+   and the status of all actors on deadlocks in MC mode.
+ - The safety/stateless aspects of the MC are now enabled by default in all simgrid builds. 
+   Liveness and stateful aspects are still controled by the enabling_model-checking 
+   configuration option.
+ - Stateless model-checking is now usable on any system, including Mac OSX and ARM processors.
+
+XBT:
+ - simgrid::xbt::cmdline and simgrid::xbt::binary_name are gone.
+   Please use simgrid::s4u::Engine::get_cmdline() instead.
 
 Documentation:
  - New section in the user guide on the provided performance models.
