How to install the latest gimp 2.9 development version on Ubuntu, via GIMP Edge PPA by Otto Kesselgulasch. Ubuntu users can install the latest release of development version of GIMP in the 2.9.x series. As you must be aware that GIMP 2.9 brings a massive update: revamped look and feel, major improvements in color management, as well as production-ready MyPaint Brush tool, symmetric painting, and split preview for GEGL-based filters. Not to forget, dozens of bugs have been fixed and it also brings various improvements.
The latest development version of GIMP features a new revamped UI and usability changes. Several new themes by Benoit Touchette has been included in various shades of gray: Lighter, Light, Gray, Dark, Darker. The system theme has been preserved for users who prefer a completely consistent look of user interfaces across all desktop applications. The new UI themes are accompanied by symbolic icons.
GIMP now keeps track of all GEGL-based filters that you used within one session and allows re-running them via the Filters > Recently Used submenu, just like old GIMP plug-ins. The new MyPaint Brush tool is now enabled by default.
