Version 0.3.11
 17-Oct-2020

common:
        * API change:
          the newly added BFLOAT16 functions were renamed to use the
          letter "B" instead of "H" to avoid potential confusion with
          the IEEE "half precision float" type, i.e. the 0.3.10
          SHGEMM is now SBGEMM and the corresponding build option
          was changed from "BUILD_HALF" to "BUILD_BFLOAT16".
        * Reduced the default BLAS3_MEM_ALLOC_THRESHOLD (used as an upper
          limit for placing temporary arrays on the stack) to be compatible
          with a stack size of 1mb (as imposed by the JAVA runtime library)
        * Added mixed-precision dot function SBDOT and utility functions
          shstobf16, shdtobf16, sbf16tos and dbf16tod to convert between
          single or double precision float arrays and bfloat16 arrays
        * Fixed prototypes of LAPACK_?ggsvp and LAPACK_?ggsvd functions
          in lapack.h
        * Fixed underflow and rounding errors in LAPACK SLANV2 and DLANV2
          (causing miscalculations in e.g. SHSEQR/DHSEQR, LAPACK issue #263)
        * Fixed workspace calculation in LAPACK ?GELQ (LAPACK issue #415)
        * Fixed several bugs in the LAPACK testsuite
        * Improved performance of TRMM and TRSM for certain problem sizes
        * Fixed infinite recursions and workspace miscalculations in ReLAPACK
        * CMAKE builds no longer require pkg-config for creating the .pc file
        * Makefile builds no longer misread NO_CBLAS=0 or NO_LAPACK=0 as
          enabling these options
        * Fixed detection of gfortran when invoked through an mpi wrapper
        * Improve thread reinitialization performance with OpenMP after a fork
        * Added support for building only the subset of the library required
          for a particular precision by specifying BUILD_SINGLE, BUILD_DOUBLE
        * Optional function name prefixes and suffixes are now correctly
          reflected in the generated cblas.h
        * Added CMAKE build support for the LAPACK and multithreading tests

        * Added support for Intel Cooperlake
        * Added autodetection of AMD Renoir/Matisse/Zen3 cpus
        * Added autodetection of Intel Comet Lake cpus
        * Reimplemented ?sum, ?dot and daxpy using universal intrinsics
        * Reset the fpu state before using the fpu on Windows as a workaround
          for a problem introduced in Windows 10 build 19041 (a.k.a. SDK 2004)
        * Fixed potentially undefined behaviour in the dot and gemv_t kernels
        * Fixed a potential segmentation fault in DYNAMIC_ARCH builds
        * Fixed building for ZEN with PGI/NVIDIA and AMD AOCC compilers

        * Added preliminary support for Apple Vortex cpus
        * Added support for the Cavium ThunderX3T110 cpu
