- Black point compensation works on multi-channel profiles
- Added more test platforms/architectures in GitHub tests, Cygwin and MSYS are now fully checked.
- jpgicc banner is not shown on normal operation, only when help is requested.
- Added a way to access internal transform pipelines. For read only.
- Add a way to retrieve the CMM signature
- Added extra checks on postscript undocumented functions
- Added guard on integer overflow when reading .cube files
- Added unneeded checks as a try to get rid of spam reports about "vulnerabilities" that are not real.
- Utility program names generated by Visual Studio 2026 are now same as all other platforms.
- Creating an output profile by cmsTransform2DeviceLink does not propagate correctly the colorant table. Fixed.
- Added some profile class definitions from iccMAX
- Deprecated uint16 and uint32 types removed from tiffdiff
- fixed generation of tiffdiff on Cmake and meson

Little CMS intends to be an open source small-footprint color management engine, with special focus on accuracy and performance. It uses the International Color Consortium standard (ICC), which is the modern standard when regarding to color management. The ICC specification is widely used and is referred to in many International and other de-facto standards. It was approved as an International Standard, ISO 15076-1, in 2005.
