+ - 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 missing thread initialization for static builds on Windows/MSVC
+ - fixed an excessive read in ZSYMV
+
+POWER:
+ - added support for POWER10 in big-endian mode
+ - added support for building with CMAKE

+ - added a generic ARMV8SVE target  
+ - added SVE-enabled SGEMM and DGEMM kernels for ARMV8SVE and A64FX
+ - added optimized CGEMM and ZGEMM kernels for Cortex A53 and A55 cpus
+ - fixed cpuid detection for Apple M1 and improved performance
+ - improved compiler flag setting in CMAKE builds
+
+RISCV64:
+ - fixed improper initialization in CSCAL/ZSCAL for strided access patterns
+
+MIPS:
