CURRENT GIMP VERSION
GIMP 2.8.16


If you've only switched over to Gimp recently you should know that Gimp 2.8 is a big jump over 2.6 (2.7 was like the testing phase of 2.8). One major change is that Gimp has a single window mode that's similar to pretty much all of the graphics programs around. Other things included enhanced sliders, more brushes, layer grouping, cage transforming, a text box offering more text options, save image split into 2 options: save (gimp format) / export (jpg, png, bmp, tif, tga...) and more. One major change when using the X button to close Gimp basically closes everything at once and exits Gimp. Before, the X button was used to close the current image only.

2.8.16 replaces version 2.8.14. That's a 0.02 change! So as you can imagine it's not a major update over the previous version, but a welcomed one nonetheless.

In this release there are bug fixes and you can catch the list of updates here: https://git.gnome.org/browse/gimp/plain/NEWS?h=gimp-2-8
Gimp 2.9 is currently in the works. It's labelled as very unstable but if your curiousity overcomes you then go ahead and try it out

Of course they warn you not to use it for production/serious work, so think of it as if you are visiting a construction site and you're just there to look around.
Release date: 21 November 2015
