 - Add a set of unit tests for bases
 - Extend the documentation of these bases
 - Remove `DiscreteScalarGlobalBasisFunction`. This was replaced by `DiscreteGlobalBasisFunction`.
+- Introduce inteface method `NodeIndexSet::indices(it)` that must write all global
+  indices for the bound tree into the container pointed to by the iterator `it`
+- Remove `NodeIndexSet::index(i)` for computation of individual global indices.
+- `DefaultLocalIndexSet::bind(...)` now computes and caches all global indices
+  while `DefaultLocalIndexSet::index(...)` is just a cheap lookup in the cache.
+- `Dune::Functions::Optional` was removed. Please use `Dune::Std::optional` instead.
+- Dune-functions now requires at least GCC 5 and uses C++14. As a consequence
+  Debian 8 is no longer supported and tested.
+- An implementation of a global Raviart-Thomas basis provided by Jakub Both was merged.
+  This is still incomplete and considered experimental.
