All platforms will benefit from a change to the image window hierarchy in single window mode, which improves painting performance when certain GTK+ themes are used.
GIMP 2.9.6 Changelog:
- Make it possible to use multithreading in GEGL and raise max amount of threads to 64. Given how unstable this feature is, any value above 1 should be currently treated as a step inside an industrial microwave oven with the on/off switch on the outside.
- New clipboard implementation allows copying/pasting layers and layer groups.
- Color tags simplify managing large projects with a lot of layers and layer groups.
- The Mouse Pointer dialog and colors applied to images are now color-managed.
- Gamma and precision selectors for newly created images.
- Never dither when converting to a higher bit depth, or to anything more than 16 bits; don't offer dithering options in these cases.
- Default to linear TRC when converting to 16-bit float.
- Pre-initialize some babl-based pixel format conversion routines at start-up to decrease the initial lazy intialization cost for some interactions.
- Remove max size limitation of 4GB for XCF files.
- Support clipboard images in the clipboard brush and pattern.
- libgimp calls are now thread-safe.
- Layer modes' code is now refactored to separate gamma-corrected variations from the linear light ones, legacy modes have been preserved to support older XCF files. UI to switch between the two is experimental and should be treated as a temporary design.
- Blending and compositing of layers are configurable separately for more flexibility now, compositing can be linear TRC, perceptual TRC or CIE LAB.
- Layer blending color space and compositing color space are configurable now.
