+SimGrid (3.28.1) NOT RELEASED YET (v3.29 expected September 22. 2021, 19:21 UTC)
+
+New features:
+ - Non-linear resource sharing: allows to dynamically change the resource
+ capacity. Users can change this capacity by setting a callback which will
+ be called when SimGrid is sharing the resource between the active
+ activities. An activity can be a task running, a read/write IO operation or a
+ communication flow.
+ - Callback signature: double (double capacity, int n_activities): given the
+ current resource's capacity and number of activities running on it,
+ returns the new capacity.
+ - Note that this callback is in the critical path of the system solve and
+ should not take long to execute.
+ - Examples:
+ - Disk: examples/cpp/io-degradation
+ - Link: examples/cpp/network-nonlinear
+ - CPU: examples/cpp/exec-cpu-nonlinear
+
+S4u:
+ - New: s4u::Disk::set_sharing_policy() and s4u::Host::set_sharing_policy().
+ Allows the configuration of non-linear resource sharing for hosts and
+ disks.
+Documentation:
+ * New section "Release Notes" documenting recent and current developments.
