- Update to version 0.3.8
  common:
  * LAPACK has been updated to 3.9.0 (plus patches up to January 2nd, 2020)
  * CMAKE support has been improved in several areas including cross-compilation
  * A thread race condition in the GEMM3M kernels was resolved
  * The "generic" (plain C) gemm beta kernel used by many targets has been sped up
  * An optimized version of the LAPACK trtrs functions has been added
  * An incompatibilty between the LAPACK tests and the OpenBLAS implementation of XERBLA
    was resolved, removing the numerous warnings about wrong error exits in the former
  * Support for NetBSD has been added
  * Support for compilation with g95 and non-GNU versions of ld has been improved
  * Compilation with (upcoming) gcc 10 is now supported
  power:
  * Worked around miscompilation of several POWER8 and POWER9 kernels by
    older versions of gcc
  * Added support for big-endian POWER8 and for compilation on AIX
  * Corrected bugs in the big-endian support for PPC440 and PPC970
  * DYNAMIC_ARCH support is now available in CMAKE builds as well
  armv8:
  * Performance of DGEMM_BETA and SGEMM_NCOPY has been improved
  * Compilation for 32bit works again 
  * Performance of the RPCC function has been improved
  * Improved performance on small systems
  * DYNAMIC_ARCH support is now available in CMAKE builds as well
  * Cross-compilation from OSX to IOS was simplified
  x86-64:
  * A new AVX512 DGEMM kernel was added and the AVX512 SGEMM kernel was
    significantly improved
  * Optimized AVX512 kernels for CGEMM and ZGEMM have been added
  * AVX2 kernels for STRMM, SGEMM, and CGEMM have been significantly

openSUSE specific packaging
===========================

OpenBLAS provides optimized implementations of BLAS and LAPACK.
openSUSE provides three variants:
 * Serial library (libopenblas_serial0)
 * With OpenMP support (libopenblas_openmp0)
 * With threading support (libopenblas_pthreads0)

By defult openSUSE uses pthreads version on x86 systems and OpenMP
for other architectures. On x86 systems OpenBLAS uses dynamic
architectures support, so it contains all CPU-related optimizations.

How to switch between the various BLAS/LAPACK implementations
=============================================================

BLAS:
 sudo /usr/sbin/update-alternatives --config libblas.so.3

LAPACK:
 sudo /usr/sbin/update-alternatives --config liblapack.so.3
