+ - Deprecate {Comm,Io,Exec}::{wait_any,wait_all,test_any} and friends
+ - New function NetZone::add_route(host1, host2, links) when you don't need gateways
+ Also add a variant with s4u::Link, when you don't want to specify the directions
+ on symmetric routes.
+ - Introduce a Mailbox::get_async() with no payload parameter. You can use the new
+ Comm::get_payload() once the communication is over to retrieve the payload.
+ - Implement recursive mutexes. Simply pass true to the constructor to get one.
+ - Introduce a new MessageQueue abstraction and associated Mess simulated object.
+ The behavior of a MessageQueue is similar to that of a Mailbox, but intended for
+ control messages that do not incur any simulated cost. Information is automagically
+ transported over thin air between producer and consumer. See examples/cpp/mess-wait
+
+SMPI:
+ - New SMPI_app_instance_join(): wait for the completion of a started MPI instance
+ - MPI_UNIVERSE_SIZE now initialized to the total amount of hosts in the platform
+
+sthread:
+ - Implement recursive pthreads.
+ - Many bug fixes.
