The developers of GIMP (GNU Image Manipulation Program), an application that can be used as a simple paint program or as an expert quality photo retouching program, have made it really easy to install the latest version of their software in Ubuntu 13.10 (Saucy Salamander).GIMP doesn't have the most alert development cycle, and it takes quite a while between releases. If you're dying to get your hands on the latest development version, 2.9.1, also called the Goat Invasion, and you are using an Ubuntu system, here is your chance.
This version of GIMP, 2.9.1, will eventually evolve into GIMP 2.10 stable and will include a host of new features, like GTK3 support, higher bit depths, script recording and playback, and much more.
The installation of GIMP in Ubuntu 13.10 is very simple and is done with the help of a PPA. Just enter the following commands in a terminal:
sudo add-apt-repository ppa:otto-kesselgulasch/gimp-edge
sudo apt-get update
sudo apt-get install gimp
You can also download GIMP 2.9.1 right now from Softpedia, if you prefer to compile your own version.
