The free alternative to Photoshop, GIMP, has a major 2.8 update that gives the user a slew of new features and a snazzy new look. The new look completely overhauls the UI and offers a single window that most Photoshop users have become accustomed to. Earlier version had multiple windows, which could ultimately get daunting and scare away many users willing to try the free alternative to the image edition giant. However, if you prefer multiple windows, GIMP lets you choose between the two.
Aside from the new look, version 2.8 lets you set up multiple columns, edit text on the canvas and group layers. The way you export and save images has been tweaked as well. You can read all about the changes here
GIMP 2.8’s source code is available for free from GIMP’s website. If you like a version that you won’t need to compile the code before running the app, the Mac version will be available soon.
