-## clBLAS update notes 09/2015
-
-- Introducing [AutoGemm](http://github.com/clMathLibraries/clBLAS/wiki/AutoGemm)
-  - clBLAS's Gemm implementation has been comprehensively overhauled to use AutoGemm. AutoGemm is a suite of python scripts which generate optimized kernels and kernel selection logic, for all precisions, transposes, tile sizes and so on.
-  - CMake is configured to use AutoGemm for clBLAS so the build and usage experience of Gemm remains unchanged (only performance and maintainability has been improved). Kernel sources are generated at build time (not runtime) and can be configured within CMake to be pre-compiled at build time.
-  - clBLAS users with unique Gemm requirements can customize AutoGemm to their needs (such as non-default tile sizes for very small or very skinny matrices); see [AutoGemm](http://github.com/clMathLibraries/clBLAS/wiki/AutoGemm) documentation for details.
