 Changes from version 2.0 which are relevant for developers:
-- Added regtests for plumed as a library (e.g. basic/rt-make-0).
+- Added regtests for plumed as a library (e.g. basic/rt-make-0). plumed command has an additional
+  flag (--is-installed) to probe if running from a compilation directory or from a fully installed copy
+  (this is needed for regtests to work properly).
 - Improved class Communicator. Many operations can now be done directly on Vectors, Tensors, and std::vector.
 - Patches for GPL codes (QuantumEspresso and Gromacs) now also include
   original code so as to simplify their modification.
