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

2018-02-18 babl-0.1.44

Fix bug in custom primaries/ICC fast paths, improve meson build

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.

2017-11-15 babl-0.1.38

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.

Build and install HCY color space, platform independences fixes to fish cache.

2017-02-01 babl-0.1.24

Improvements to profile cache persistance, fast paths that improve actual GIMP use on various precisions, use single precision constants for some more of CIE computions.

2016-11-05 babl-0.1.22

Added cache of profiled conversions, added HCY color model, some precision and performance updated for fast paths.

2016-11-05 babl-0.1.20

Fix run-time errors, leaks, and race conditions. Add conditional fast paths.

2016-06-13 babl-0.1.18

Bugfix: take alpha threshold in consideration when processing floats in SSE2.

2016-02-12 babl-0.1.16

Improvements to half float reference, SIMD, and fast-paths, and CIE float fast paths; cleanups of fast path extensions.

2015-11-19 babl-0.1.14

2009-05-20 babl-0.1.0

Support for RGBA representation in the frequency domain, un-pre-multiply close-to-zero alpha values to complete black instead of slightly brighter than black, add a BABL_ALPHA_THRESHOLD constant to the API, do a complete overhaul of the babl API and do some changes to increase portability of the library.

2008-06-12 babl-0.0.22
