+## Parallelism
+  - The TTaskGroup class has been added to the ROOT::Experimental namespace. It allows to submit to the runtime
+  item of work which are dealt with in parallel;
+  - The Async template function has been added the ROOT::Experimental namespace. The template function is analogous
+  to *std::async* but without the possibility of specifying the execution policy and without creating a thread but
+  directly submitting the work to the runtime in order to use the same pool as any other item of work spawned by ROOT.
+  - The TFuture template has been added to the ROOT::Experimental namespace. It represents a future and is compatible
+  with the ROOT::Experimental::Async function. It has the same properties of an STL future and can be initialised by
+  one of these classes. For example, *TFuture<int> = std::async(myfunc,a,b,c);*
