+ - Hide the examples into examples/deprecated. New users should use Python.
+
+MSG:
+ - Drop MSG_process_create_from_stdfunc() from the API.
+ This C++ function was a pimple in the C API, made necessary at some
+ point by the Java bindings. This is fixed now.
+ - Hide the examples into examples/deprecated. New users should use S4U.
+ - MSG_process_create and MSG_process_attach now crash if the host used
+ to run this process is off.
+ - Fix the protype of MSG_process_on_exit()
+ Now use (int,void*) callbacks instead of (void*,void*) ones.
+ The implementation was ways too messy to actually work, I guess.
+
+SMPI:
+ - Change the way SMPI_SAMPLE_* macros work to avoid invalidating cache
+ too often and provide more accurate timings.
+
+XBT:
+ - Drop sg_cmdline. Please use xbt_cmdline instead.
+ - Drop the C xbt_os_mutex_t; Use the C++11 std::mutex.
+ - Drop the C xbt_os_sem_t; Use the C++ xbt::OsSemaphore.
+ OsSemaphore is implemented in a portable way with C++11 threads.
+ This should allow much more threads to be created at the same time,
+ allowing Mac and Java users to simulate many more actors.
+ - Implement the 'thread' factory with std::thread instead of xbt ones.
+ It is not possible to set the stack size with threads anymore, but
+ -fsplit-stack is the way to go nowadays when using threads.
+ - Drop the xbt_os_thread_t module (now unused)
+ - Drop xbt_ex_display(), use simgrid::xbt::log_exception() instead.
+ - Drop cunit, use Catch2 instead.
+
+Kernel:
+ - Many cleanups in the kernel::activity namespace. This was long
+ overdue, and shall open the path to many future endeavors.
