general:

reverted unsafe TRSV/ZRSV optimizations introduced in 0.3.16
fixed a potential thread race in the thread buffer reallocation routines that were introduced in 0.3.18
fixed miscounting of thread pool size on Linux with OMP_PROC_BIND=TRUE
fixed CBLAS interfaces for CSROT/ZSROT and CROTG/ZROTG
made automatic library suffix for CMAKE builds with INTERFACE64 available to CBLAS-only builds

x86_64:

DYNAMIC_ARCH builds now fall back to the cpu with most similar capabilities when an unknown CPUID is encountered, instead of defaulting to Prescott
added cpu detection for Intel Alder Lake
added cpu detection for Intel Sapphire Rapids
added an optimized SBGEMM kernel for Sapphire Rapids
fixed DYNAMIC_ARCH builds on OSX with CMAKE
worked around DYNAMIC_ARCH builds made on Sandybridge failing on SkylakeX

fixed an excessive read in ZSYMV

POWER:

added support for POWER10 in big-endian mode
added support for building with CMAKE
added optimized SGEMM and DGEMM kernels for small matrix sizes

ARMV8:
