 With this addition Gromacs allows to choose from two schemes to soften
 non-bonded interactions during alchemical perturbations:
 Beutler *et al.*\ :ref:`100 <refBeutler94>` and Gapsys *et al.*\ :ref:`185 <refGapsys2012>` soft-core functions.

+With the accelerated weight histogram method, biases can now be shared between
+subsets of all simulations, without restrictions. The allows for more flexible
+ensemble simulation setups, as well as simpler launches of sets of simulations.
