                 ------------------------------------

                                                                 17 June 2016

List of fixes included in this public patch since the public release 10.2.p01:

  o Configuration:
    -------------
    + CMake:
      o Enhanced advanced option for use of external USolids/VecGeom library;
        it is now possible to select individual shapes for partial use of the
        set of primitives provided by the library, by specifying through the
        GEANT4_USE_USOLIDS the list of primitives to consider, i.e. using:
        -DGEANT4_USE_USOLIDS="box;tubs" will replace box and tubs shapes with
        USolids/VecGeom ones; -DGEANT4_USE_USOLIDS="all" or -DGEANT4_USE_USOLIDS
        will replace with all shapes enabled in the library.

        installation. Addressing problem report #1855.
