Release Notes

Significant changes relative to 3.0.0:

1. The x86-64 SIMD functions now use a standard stack frame, prologue, and epilogue so that debuggers and profilers can reliably capture backtraces from within the functions.

2. Fixed two minor issues in the interblock smoothing algorithm that caused mathematical (but not necessarily perceptible) edge block errors when decompressing progressive JPEG images exactly two DCT blocks in width or that use vertical chrominance subsampling.

3. Fixed a regression introduced by 3.0 beta2[6] that, in rare cases, caused the C Huffman encoder (which is not used by default on x86 and Arm CPUs) to generate incorrect results if the Neon SIMD extensions were explicitly disabled at build time (by setting the WITH_SIMD CMake variable to 0) in an AArch64 build of libjpeg-turbo.
