We are not going to list the full changelog here, since you can get a
better idea with our official GIMP 2.10 release
notes. To get an even more
detailed list of changes please see the
NEWS file.
Still, to get you a quick taste of GIMP 2.10, here are some of the most
notable changes:
Image processing nearly fully ported to GEGL,
allowing high bit depth processing, multi-threaded and hardware
accelerated pixel processing, and more.
Color management is a core feature now, most widgets and preview areas
are color-managed.
Many improved tools, and several new and exciting tools, such as the
Warp transform, the Unified transform and the Handle transform tools.
On-canvas preview for all filters ported to GEGL.
Improved digital painting with canvas rotation and flipping, symmetry
painting, MyPaint brush support…
Support for several new image formats added (OpenEXR, RGBE, WebP, HGT), as
well as improved support for many existing formats (in particular
more robust PSD importing).
Metadata viewing and editing for Exif, XMP, IPTC, and DICOM.
Basic HiDPI support: automatic or user-selected icon size.
New themes for GIMP (Light, Gray, Dark, and System) and new symbolic
icons meant to somewhat dim the environment and shift the focus
towards content (former theme and color icons are still available in Preferences).
