GIMP 2.10 Finally Reaches The Release Candidate Stage
Given GIMP 2.10-RC1 is comprised of years worth of changes in the GIMP 2.9 unstable series and even four months since the release of the GIMP 2.9.8 release, there is a ton of new features. GIMP 2.10-rc1 includes a dashboard dock for monitoring its resource usage, a new debug dialog when GIMP crashes, a new shadows-highlights filter, masks on layer groups are now supported, JPEG 2000 support was ported to OpenJPEG, screenshots support using the FreeDesktop API to allow for eventual Wayland support, GEGL library updates, and a whole lot more.
Find out all about the very exciting GIMP 2.10 Release Candidate via GIMP.org. Hopefully it won't be much longer now before hearing of the GIMP 2.10.0 stable release.
Keep in mind though the GIMP 2.x releases are still on the GTK2 tool-kit with still needing to finish the program's port to GTK3. GIMP 3.x will still likely be a ways out.
