- Update to version 0.3.27 (boo#1225869):
  General:
  * Added initial (generic) support for the `CSKY` architecture.
  * Capped the maximum number of threads used in `GEMM`, `GETRF`
    and `POTRF` to avoid creating underutilized or idle threads.
  * Sped up multithreaded `POTRF` on all platforms.
  * Added extension `openblas_set_num_threads_local()` that returns
    the previous thread count.
  * Re-evaluated the `SGEMV` and `DGEMV` load thresholds to avoid
    activating multithreading for too small workloads.
  * Improved the fallback code used when the precompiled number of
    threads is exceeded,  and made it callable multiple times
    during the lifetime of an instance.
  * Added CBLAS interfaces for the BLAS extensions `?AMIN`,`?AMAX`,
    `CAXPYC` and `ZAXPYC`.
  * Fixed a potential buffer overflow in the interface to the
    `GEMMT` kernels.
  * Fixed use of incompatible pointer types in `GEMMT` and
    `C`/`ZAXPBY` as flagged by GCC-14.
  * Fixed unwanted case sensitivity of the character parameters in
    `?TRTRS` sped up the OpenMP thread management code.
  * Fixed sizing of logical variables in `INTERFACE64` builds of
    the C version of LAPACK.
  * Fixed inclusion of new LAPACK and LAPACKE functions from
    LAPACK 3.11 in the shared library.
  * Modified the error thresholds for `SGS`/`DGS` functions in
    the LAPACK testsuite to suppress spurious errors.
  * Added support for calling ?NRM2 with a negative increment value
    on all architectures.
  * Fixed handling of the `OPENBLAS_LOOPS` variable in several

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
