ELPA_2019.05.002_release

• repacking of the src since the legacy interface has been forgotten in the
  2019.05.001 release
• elpa_print_kernels supports GPU usage
• fix an error if PAPI measurements are activated
• new simple real kernels: block4 and block6
• c functions can be build with optional arguments if compiler supports it
  (configure option)
• allow measurements with the likwid tool
• users can define the default-kernel at build time
• ELPA versioning number is provided in the C header files
• as announced a year ago, the following deprecated routines have been finally
  removed; see DEPRECATED_FEATURES for the replacement routines , which have
  been introduced a year ago. Removed routines:
  -> mult_at_b_real
  -> mult_ah_b_complex
  -> invert_trm_real
  -> invert_trm_complex
  -> cholesky_real
  -> cholesky_complex
  -> solve_tridi

ELPA_2018.11.001_release

• improved autotuning
• improved performance of generalized problem via Cannon's algorithm
• check pointing functionality of elpa objects
• store/read/resume of autotuning
• Python interface for ELPA
• more ELPA functions have an optional error argument (Fortran) or required
  error argument (C) => ABI and API change
