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.

Changes:
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
