The Gimp 2.10.0

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).

GUI:
Improve drawing performance in single window mode, especially with pixmap themes.
MacOS DMG:
Make the launcher script also set BABL_PATH.
Add patch for GTK+ Bug 743717 to the build which concerns crashes during clipboard operations with a clipboard manager active.
Add patch for GTK+ Bug 767091 to the build which concerns crashes on some drag & drop operations.
Generate OSX package metadata during build.
Plug-ins:
Fix for CVE-2007-3126, a bug in the ICO plug-in which allowed context-dependent attackers to cause a denial of service (crash) via an ICO file with an InfoHeader containing a Height of zero. We couldn't reproduce any crash in recent version, but fixed the error messages for good measure.
Avoid creating wrong layer group structure when importing PSD files (already fixed in 2.8.20, didn't make it to the NEWS).
Prevent a crash in PDF plug-in if images or resolution are large.
stop parsing invalid PCX files early and prevent a segmentation fault.
General:
If NOCONFIGURE is set, autogen.sh won't run configure.
VPATH builds for win32 targets have been fixed.
