- 10/26: 0.1.6: build-time trimming, SJPEG_NO_{RISKINESS,SHARP_YUV,SEARCH,
    ADAPTIVE_QUANT,METADATA,C_FALLBACK} (CMake SJPEG_ENABLE_*, make SJPEG_HAVE_*)
- 10/26: 0.1.5: add EncoderParam::fast_mode (-fast): sampled statistics and
    search passes, cheaper trellis
- 10/26: 0.1.4 release
  * add progressive JPEG encoding, restart markers, multithreaded encoding
  * add fast RDO and adaptive-bias quantization
  * add native RGBA/BGRA inputs
  * add AVX2 variants => speed up SSE2/SSSE3/NEON paths (fdct, quantization,
    histogram, trellis, color conversion, sharp-YUV, riskiness)
  * faster progressive riskiness scoring (~2.6x)
  * MSVC x86/ARM64 SIMD support
  * thread-safety and overflow fixes
  * build: pkg-config, 'check' target, unit_test, CI, clang-format
- 01/20: add YUV400 (grayscale) support
- 03/18: add search hooks, SetMinQuantization(), NEON QuantizeError
- 11/17: initial release version 0.1
