Simd Library Release Notes (2026).

January 2, 2026 (version 6.2.157)

Algorithms

New features

• Function Simd::Resize for Simd::Frame.
• Base implementation of function DrawLine.
• Base implementation of function DrawRectangle.
• Base implementation of function FontInit.
• Base implementation of function FontResize.
• Base implementation of function FontHeight.
• Base implementation of function FontMeasure.
• Base implementation of function FontDraw.

Improving

• Base implementation, AMX-BF16 optimizations of class SynetConvolution16bNhwcGemmV1.
• AVX-512BW optimizations of function SynetPoolingMax32f (case of SynetPoolingMax32f2DNhwcSolid2x2).
• AVX-512BW optimizations of function SynetMergedConvolution32f (InputConvolution1x1).
• AVX-512BW optimizations of function SynetMergedConvolution32f (DepthwiseConvolution_k3p1d1s1w6).
• Simd::DrawLine uses SimdDrawLine instead its own implementation.
• Simd::DrawRectangle uses SimdDrawRectangle instead its own implementation.
• Simd::Font uses functions SimdFontInit, SimdFontResize, SimdFontHeight, SimdFontMeasure, SimdFontDraw instead of its own implementation.
