+====================================================================
+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
+
+POWER:
+	* Added optimized support for POWER10
+	* Added support for compiling for POWER8 in 32bit mode
+	* Added support for compilation with LLVM/clang
+	* Added support for compilation with NVIDIA/PGI compilers
+	* Fixed building on big-endian POWER8
+	* Fixed miscompilation of ZDOTC by gcc10
+	* Fixed alignment errors in the POWER8 SAXPY kernel
+	* Improved CPU detection on AIX
+	* Supported building with older compilers on POWER9
+

+	* 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
+	
+ARMV7:
+	* Fixed cpu detection on BSD-like systems
+
+ARMV8:
+	* Added preliminary support for Apple Vortex cpus
+	* Added support for the Cavium ThunderX3T110 cpu
+	* Fixed cpu detection on BSD-like systems
+	* Fixed compilation in -std=C18 mode
+
+IBM Z:
+	* Added support for compiling with the clang compiler
