+ - New: Host.execute() for remote executions.
+
+ SURF
+ - Unused option network/sender-gap is removed.
+
+ MSG
+ - Deprecate MSG_task_isend_with_matching(): This unused feature

+ when a process is forcibly killed.

+ xbt_str_rtrim(), xbt_str_trim().
+ - xbt/xbt_os_thread.h: xbt_os_thread_cancel(), xbt_os_thread_detach().
+

+ - #186: Actor::killAll() segfaults if some process is blocked on wait()
+ - #191: VM migration and pstate
+ - #192: Updating the energy consumptions of all hosts crashes with VMs
+ - #195: All actors have PID=0 in the logs
+ - #204: Sometimes segfault with thread contexts and mmap privatization
