+ - Hide the examples into examples/deprecated. New users should use S4U.
+
+XBT:
+ - Drop sg_cmdline. Please use xbt_cmdline instead.
+ - 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 several unused xbt_os_thread_t functions:
+ - xbt_os_thread_exit()
+ - xbt_os_thread_get_extra_data()
+ - xbt_os_thread_set_extra_data()
+ - xbt_os_thread_self()
+ - xbt_os_thread_self_name()
+ - xbt_os_thread_setstacksize()
+ - xbt_os_thread_setguardsize()
+ - Drop xbt_ex_display(), use simgrid::xbt::log_exception() instead.
