* **Feature:** The core codec now supports arm64 for both MSVC `cl.exe` and
`clangcl.exe` compilers.
- * **Feature:** `NO_INVARIANCE` builds with AVX2 will enable `-mfma` and
- `-ffp-contract=fast` when using Clang or GCC. This reduces image quality
- by up to 0.2dB (normally much less), but improves performance by 10-15%.
+ * **Feature:** `NO_INVARIANCE` builds will enable the `-ffp-contract=fast`
+ option for all targets when using Clang or GCC. In addition AVX2 targets
+ will also set the `-mfma` option. This reduces image quality by up to 0.2dB
+ (normally much less), but improves performance by up to 5-20%.
* **Optimization:** Angular endpoint min/max weight selection is restricted
to weight `QUANT_11` or lower. Higher quantization levels assume default
0-1 range, which is less accurate but much faster.
