OpenBLAS ChangeLog
====================================================================
Version 0.3.17
15-Jul-2021
common:
- reverted the optimization of SGEMV_N/DGEMV_N for small input sizes
and consecutive arguments as it led to stack overflows on x86_64
with some operating systems (notably OSX and Windows)
x86_64:
- reverted the performance patch for SGEMV_T on AVX512 as it caused
wrong results in some applications
SPARC:
- fixed compilation with compilers other than gcc
====================================================================
Version 0.3.16
11-Jul-2021
