In the face of all sorts of rumours and interpretations about the future of the project there is a call for clarification regarding development of GIMP.
Currently GIMP team is working on finalizing the new stable v2.8 with many improvements such as layer groups, improved brush dynamics, a new unique transformation tool, optional single-window mode and more. There are two big obstacles in our way right now: missing specification on the last change in user interface and broken graphic tablets support in GTK+.
We have already invested a lot of time into UI changes and brush dynamics, we treasure your continuous support for the project and thus we are determined to release v2.8 only when it’s working out of box as expected for everybody.
After releasing v2.8 the focus of development will shift to deep integration of GEGL — our new non-destructive image processing core. Results of this work will enable many features considered critical for use of GIMP in professional environment which is part of GIMP’s product vision. It’s a lot of work, and currently we don’t have enough developers to make this change happen very fast. If you want to help us to get there faster, we encourage you to join gimp-developer mailing list and/or the IRC channel to discuss how you could contribute.
