SLEEF (SIMD Library for Evaluating Elementary Functions) is a library that facilitates programming with SIMD instructions. It implements the trigonometric functions, inverse trigonometric functions, exponential and logarithmic functions in double precision without table look-ups, scattering from, or gathering into SIMD registers, or conditional branches. This library also includes some functions for evaluation in single precision.

This release adds support for the ARM NEON instruction set. Higher accuracy single precision functions were added: sinf_u1, cosf_u1, sincosf_u1, tanf_u1, asinf_u1, acosf_u1, atanf_u1, atan2f_u1, logf_u1, and cbrtf_u1
