 OpenBLAS ChangeLog
+====================================================================
+Version 0.3.7
+11-Aug 2019
+
+common:
+        * having the gmake special variables TARGET_ARCH or TARGET_MACH
+          defined no longer causes build failures in ctest or utest
+        * defining NO_AFFINITY or USE_TLS to 0 in gmake builds no longer
+          has the same effect as setting them to 1
+        * a new test program was added to allow checking the library for
+          thread safety
+        * a new option USE_LOCKING was added to ensure thread safety when
+          OpenBLAS itself is built without multithreading but will be 
+          called from multiple threads.
+        * a build failure on Linux with glibc versions earlier than 2.5
+          was fixed
+        * a runtime error with CPU enumeration (and NO_AFFINITY not set)
+          on glibc 2.6 was fixed
+        * NO_AFFINITY was added to the CMAKE options (and defaults to being
+          active on Linux, as in the gmake builds)
+
+x86_64:
+        * the build-time logic for detection of AVX512 availability in
+          the processor and compiler was fixed
+        * gmake builds on OSX now set the internal name of the library to 
+          libopenblas.0.dylib (consistent with CMAKE)
+        * the Haswell DGEMM kernel received a significant speedup through
+          improved prefetch and load instructions
+        * performance of DGEMM, DTRMM, DTRSM and ZDOT on Zen/Zen2 was markedly
+          increased by avoiding vpermpd instructions
+        * the SKYLAKEX (AVX512) DGEMM helper functions have now been disabled
+          to fix remaining errors in DGEMM, DSYMM and DTRMM
+
+## POWER:
+        * added support for building on FreeBSD/powerpc64 and FreeBSD/ppc970
+        * added optimized kernels for POWER9 SGEMM and STRMM
+
+## ARMV7:
+        * fixed the softfp implementations of xAMAX and IxAMAX
+        * removed the predefined -march= flags on both ARMV5 and ARMV6 as
+          they were appropriate for only a subset of platforms
+
+====================================================================
+Version 0.3.6
+29-Apr-2019
+
+common:
+	* the build tools now check that a given cpu TARGET is actually valid
+	* the build-time check of system features (c_check) has been made
+  	  less dependent on particular perl features (this should mainly
+  	  benefit building on Windows)
+	* several problem with the ReLAPACK integration were fixed,
+	  including INTERFACE64 support and building a shared library
+	* building with CMAKE on BSD systems was improved
+	* a non-absolute SUM function was added based on the
+  	  existing optimized code for ASUM
+	* CBLAS interfaces to the IxMIN and IxMAX functions were added
+	* a name clash between LAPACKE and BOOST headers was resolved
+	* CMAKE builds with OpenMP failed to include the appropriate getrf_parallel
+	  kernels
+	* a crash on thread (key) deletion with the USE_TLS=1 memory management
+	  option was fixed
+	* restored several earlier fixes, in particular for OpenMP performance,
+  	  building on BSD, and calling fork on CYGWIN, which had inadvertently
+  	  been dropped in the 0.3.3 rewrite of the memory management code.
+
+x86_64:
+	* the AVX512 DGEMM kernel has been disabled again due to unsolved problems
+	* building with old versions of MSVC was fixed
+	* it is now possible to build a static library on Windows with CMAKE
+	* accessing environment variables on CYGWIN at run time was fixed
+	* the CMAKE build system now recognizes 32bit userspace on 64bit hardware
+	* Intel "Denverton" atom and Hygon "Dhyana" zen CPUs are now autodetected
+	* building for DYNAMIC_ARCH with a DYNAMIC_LIST of targets is now supported
+  	  with CMAKE as well
+	* building for DYNAMIC_ARCH with GENERIC as the default target is now supported
+	* a buffer overflow in the SSE GEMM kernel for Intel Nano targets was fixed
+	* assembly bugs involving undeclared modification of input operands were fixed
+  	  in the AXPY, DOT, GEMV, GER, SCAL, SYMV and TRSM microkernels for Nehalem,
+	  Sandybridge, Haswell, Bulldozer and Piledriver. These would typically cause
+	  test failures or segfaults when compiled with recent versions of gcc from 8 onward.
+	* a similar bug was fixed in the blas_quickdivide code used to split workloads
+	  in most functions
+	* a bug in the IxMIN implementation for the GENERIC target made it return the result of IxMAX
+	* fixed building on SkylakeX systems when either the compiler or the (emulated) operating
+	  environment does not support AVX512
+	* improved GEMM performance on ZEN targets
+
+x86:
+	* build failures caused by the recently added checks for AVX512 were fixed
+	* an inline assembly bug involving undeclared modification of an input argument was
+  	  fixed in the blas_quickdivide code used to split workloads in most functions
+	* a bug in the IMIN implementation for the GENERIC target made it return the result of IMAX
+
+MIPS32:
+	* a bug in the IMIN implementation made it return the result of IMAX
+
+POWER:
+	* single precision BLAS1/2 functions have received optimized POWER8 kernels
+	* POWER9 is now a separate target, with an optimized DGEMM/DTRMM kernel
+	* building on PPC970 systems under OSX Leopard or Tiger is now supported
+	* out-of-bounds memory accesses in the gemm_beta microkernels were fixed
+	* building a shared library on AIX is now supported for POWER6
+	* DYNAMIC_ARCH support has been added for POWER6 and newer
+
+ARMv7:
+	* corrected xDOT behaviour with zero INC_X or INC_Y
+	* a bug in the IMIN implementation made it return the result of IMAX
+
+ARMv8:
+	* added support for HiSilicon TSV110 cpus
+	* the CMAKE build system now recognizes 32bit userspace on 64bit hardware
+	* cross-compilation with CMAKE now works again
+	* a bug in the IMIN implementation made it return the result of IMAX
+	* ARMV8 builds with the BINARY=32 option are now automatically handled as ARMV7
+
+IBM Z:
+	* optimized microkernels for single precicion BLAS1/2 functions have been added
+	  for both Z13 and Z14
