* Updated redistributed ELPA source code to version 2020.05.001, which supports
single precision calculations, autotuning of runtime parameters, and (NVIDIA)
GPU acceleration.
* The updated ELPA code can not be compiled with the NAG Fortran compiler, due
to the use of GNU extentions in ELPA.
### PEXSI
* AAA method has become the default pole expansion method in PEXSI.
* Increased default number of poles from 20 to 30.
* Improved accuracy of pole expansion based on minimax approximation.
* Improved accuracy of pole expansion based on minimax rational approximation.
* Updated redistributed (PT-)SCOTCH source code to version 6.0.9.
### SLEPc-SIPs
* Interface compatible with PETSc 3.13 and SLEPc 3.13.
### Known issues
* The ELPA code can not be compiled with the NAG Fortran compiler, due to the
use of GNU extentions in ELPA.
* ELPA AVX kernels cannot be built with the PGI compiler suite due to incomplete
support of AVX intrinsics in PGI.
* Depending on the choice of k-points, the complex PEXSI solver may randomly
