GIMP is the GNU Image Manipulation Program and is the best Open Source image-editing suite available for Linux as well as Windows. It is completely free and has features comparable to that of Photoshop.
We recently did a post to make GIMP look and feel like Photoshop. You can go check this page for more.
GIMP has just released a new version 2.6.9 which has a huge number of bug fixes as the major changes. There are no additional features in this release. The complete list of bug fixes is available at this page. Some of the important ones fixed in this release are:
- Import PDF files with long titles.
- Shared memory leak fixes.
- Font selection remaining visible
- Layer preview stops updating.
- Histogram display made more accurate.
If you are a regular GIMP user, install GIMP 2.6.9 using,
sudo apt-get update && sudo apt-get upgrade
