  1. Fixed: Starting in release 7.1, we first built the deal.II shared libraries +in the local /tmp or similar directory rather than the final location +because linking becomes very slow over remotely mounted file systems. Unfortunately, +this schemes turns out not to work under Cygwin on Windows systems: executables +cannot link with libraries that have been moved/renamed after linking. If we are +running on Cygwin, we therefore revert to the old scheme. +

  2. New: finite element FE_Q_DG0 that implements polynomials of order k with an additional discontinuous constant function.
