+ - New functions: s4u::Comm::{sendto_init, set_source, set_destination} to enable
+ the use of vetoers with direct host-to-host communications. Both source and
+ destination have to set for a comm to start. Each call to these setters check
+ if all vetoes are satisfied. When it is the case, the comm starts. A use case of
+ these functions is given in examples/cpp/dag-scheduling.
+ - New functions: {Exec, Io}::update_priority allow you to modify the priority of
+ these kinds of activities during their execution. Behavior is detailed in
+ examples/cpp/io-priority/.
