+ - Deprecate {Comm,Io,Exec}::{wait_any,wait_all,test_any} and friends
+ - Simplify a bit the declaration of multi-zoned platforms from C++
+ - 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.
+ - Zone's gateways can now be controlled directly.
+ - Add NetZone::add_route(zone1, zone2, links) specifying the route between zones
+ - 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.
+ - Simplify the expression of horizontal scaling of Tasks.
+ - Each Task now consists of a dispatcher, a collector and one or more instances.
+ - The parallelism degree of each of these can be set.
+ - Several examples have been added or modified accordingly.
+ - Update s4u::create_DAG_from_json() to support wfformat 1.4.
+ - 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
+ - New function: Mutex::get_owner()
+
+S4U plugins:
+ - New: Add a JBOD (just a bunch of disks) concept. It's a sort of host with many disks.
+ - Revamp the battery plugin: rewrite completely the API, for a better usability.
+ The examples were updated accordingly.
+ The battery can now act as a simple connector (see battery-connector example).
+ - Revamp of the photovoltaic plugin: now called SolarPanel and complete rewrite of the API
+ - Add chiller plugin: enable the management of chillers consuming electrical energy
+ to compensate heat generated by hosts.
+ - Add a battery-chiller-solar example combining several plugins to evaluate the amount
+ of brown energy (from the electrical grid) and green energy (from the solar panel)
+ during a given computation.
