API changes
trmm and trsm now do not label argument a anymorepatt argument, which can be used to specify rectangular, triagonal, trapezoidal, and pentagonal patterns on which to perform an operation.New functions
Mat.sum_prod computes the sum of element-wise products of two matrices. Some use cases are already covered by Mat.gemm_trace, but the latter does not support patterns.-march=native -O3 -ffast-math by default, which should be safe and exploit SIMD on platforms that support it to greatly improve performance of some operations.
