OpenBLAS ChangeLog
====================================================================
Version 0.3.3
31-Aug-2018

common:
	* thread memory allocation has been switched back to the method
	  used before version 0.3.1 due to unexpected problems caused by
	  the new code under some circumstances. A new compile-time option
	  USE_TLS has been added to enable the new code, and it is hoped
	  that this can become the default again in the next version.
	* LAPAck PR272 has been integrated, which fixes spurious errors
	  in DSYEVR and related functions caused by missing conversion 
	  from ILAENV to ILAENV_2STAGE in several _2stage routines.
	* the cmake-generated OpenBLASConfig.cmake now uses correct case
	  for the name of the library
	* added support for Haiku OS  

x86_64:
	* added AVX512 implementations of SDOT, DDOT, SAXPY, DAXPY,
	  DSCAL, DGEMVN and DSYMVL

	* added an option DYNAMIC_LIST that (used in conjunction with DYNAMIC_ARCH) allows to 
	  specify the list of x86_64 targets to include. Any target not on the list will be supported 
	  by the Sandybridge or Nehalem kernels if available, or by Prescott.
	* improved SWITCH_RATIO on Haswell for increased GEMM throughput
