## old babl releases

2018-10-05 babl-0.1.60
  Improved thread safety, acceleration for R'G'B'A u8 -> cairo-ARGB32 conversion.

  Preserve color of transparent pixels in conversion to premultiplied alpha, Added single precision code-paths for faster fallback/reference conversions. New BABL_ICC_INTENT_PERFORMANCE bitflag for combining with intent as bitflags, use of matrix+trc when relative colorimetric CLUT is present. New color model and formats, CIE xyY.
2018-08-14 babl-0.1.56
  Improvements to the caching of profiled conversion chains between invocations by ignoring unknown bits in cache file and remember which conversions yielded reference fishes. 2018-07-23 babl-0.1.54

2018-05-20 babl-0.1.50
  Improvements to speed and precision of indexed code, improvements to meson build.
2018-05-15 babl-0.1.48
  fix u8 <-> double conversions for chroma, SSE2 version of RGBA float to CIE L / Lab. Build with -Ofast by default.
2018-04-10 babl-0.1.46
  added extensions with more coverage for u32, half and other utilit fast paths improving fast path coverage.
2018-02-18 babl-0.1.44

2018-01-23 babl-0.1.42
  Fully initialize fishes when loading from cache.
2018-01-16 babl-0.1.40
  Added format "CIE XYZ alpha" color model and formats. New API babl_process_rows for reduced overhead in some scenarios; though bigger gains seen also for regular babl_process with reimplemented branch-free dispatch, and faster cbrt. Added meson build; being tested in parallel with auotmake, Improved reference conversions for formats skipping some of models components, Fixed gamma handling in indexed/palettized formats and improved gamma precision consistenct in sse2 conversions.

  Added format "CIE L float", a couple of protections against division by 0.0
2017-11-10 babl-0.1.36
  Optimized customized primary aware code paths for CIE Lab<->RGB conversions, improved accuracy of gamma approximations. New API babl_format_exists() for checking validity of babl format name, crash proofing of cache handling and use of environment variables.
2017-10-06 babl-0.1.34
  Brown paper bag release, Fix indexed / custom primaries conflict, and re-export a symbol used by old GEGL/GIMPs.
2017-10-03 babl-0.1.32
  Added custom primaries and TRC support through ICC parsing, improved float<->half performance, rewrite of all conversions functions to adhere to new signature.
2017-07-15 babl-0.1.30
