Argyll CMS: vanhemmat versiot ja versiohistoria

- Added MSWindows ARM release.
- Added Mac ARM release.
- Removed Mac PowerPC build from release.
- Changed colprof so that rather than just warning about an ink limit being set for an additive device space, it ignores it.
- Fixed bug in targen introduced in V3.3.0 where it adds a default ink limit for all device types. If not overidden later in the profiling process, this can introduce an ink limit 10% less than the unconstrained limit. This is a problem for additive devices.
- Fixed reported problem with some models of Spyder2024.
- Took a stab at adding libusb-win32 ARM64 system driver support. Reported to work, but installing libusb-win32 system driver is more difficult.
- Added Munsell Linear Grayscale scanin reference files. (Thanks to Tarek A. Haila and Frank Schaumann)
- Added -g option to xicc/fakeCMY to emit RGB values rather than CMY values.
- Tweaked i1d3 frequency measurement mode to return exactly zero on measuring perfect black rather than the correctly rounded value, so as to make it more consistent with the period measurement mode. This inconsistency shows up with a Rev. B when I1D3_DISABLE_AIO is set and the 0x83 bug is triggered, and frequency measurement is used as a fallback to period measurement mode. Rev. A instruments shouldn't see any change since for them the period measurement mode doesn't suffer from the 0x83 bug.
- Added -o observer option to xicc/specplot.
- Improved robustness of command name filename parsing in a number of utilities.
- Expand spectro/average to handle input test charts.
- Improve JETI Specbos 2501 operation.

- Added support for Spyder and SpyderPRO (2024)
- Renamed proposed CIE 2012 2 and 10 degree to standard CIE 2015 2 and 10 degree observers, as per CIE 170-2:2015.
- Added -Y c: option to colprof and invprofcheck to allow setting/overriding alibration curves for setting final ink limits.
- Added -Y c: option to xicclu to allow setting/overriding calibration curves for setting final ink limits, and added -T flag to show ink limits.
- Fixed Spyder X and X2 to not make Device Disconect noise (if such sounds are enabled) on MSWin.
- Fixed bug in colprof -nI failing for CMYK profiles.
- Enhanced strip reader patch recognition to reject strips that don't start and end on the media, as well as adding some speed compensation to the patch recognition for non-zerbra ruler measurements.
- Fixed bug in i1Pro3 strip reading where it would return bad values if the zerbra stripe wasn't used.
- Changed chartread so that it will issue warnings of possible bad row or patch reading even when .ti2 reference measurement is not accurate (i.e. no preconditioning profile used in targen.)
- Increased emphasis of making sure that there is contrast between patches at the end of rows in printtarg patch ordering for strip instruments.
- Added -C parameter to targen to allow overriding any calibration curves found in the ICC profile, used to estimage the total ink limit from that in the ICC profile. Also better enforces final raw computes ink limits.
- Modified ccxxmake so that it checks that it has actually found a white seeming patch to use as the L*a*b* white reference, and the patch to de-weight. If there is no white patch (i.e. just RGB patches) then it will use D65 as the L*a*b* conversion reference. ccxxmake will fail if there are less than 3 patches.
- Fixed ICC profile writing so that it clips rather than failing when writing a ColorantTable PCS value that is out of range. A warning to stderr will be issued.
- Changed ColorMunki driver so that it is more forgiving about unexpected version string lengths.
- Fixed dispcal and dispread so that they won't error out if there is no instrument but the -M parameter is provided.

- Improved reliability of i1Pro2 startup by adding recovery delay after the getmisc instruction.
- Fixed i1pro2/3 driver to be more forgiving of wavelength calibration pushing filter offsets outside the range of raw CCD range.
- Fixed numerical bug in targen when using -V and -c with profile with zero black.
- Added support for Spyder X2 (thanks to Chris Minasians and A.K. for helping make an instrument available).
- Added support for JETI 2501 spectrometer thanks to to Omardis.
- Added -T option to targen to allow separate total ink limit for text and spacer text.
- Modified targen CMYK chart generation to apply a level of luminance boost to the resulting OFPS samples. This partially compensates for the overall darkening of the test set due to exploring the combined K response of the device. While this will reduce the sampling density and resulting profile accuracy in darker parts of the gamut, it should improve the accuracy of colors for realistic prints, which typically have a lighter average than the device CMYK gamut.
- Added extra diagnostics and -p plot detail to printcal. Added -z flag to allow setting a resulting calibration table resolution to values other than 256.
- Fix 3.2.0 bug introduced into spectro/Jamfile install that omitted spec2cie from binary distributions.
