Just a quick post to let you know that I'm currently putting the finishing touches to version 2.60. There is still a little tweaking and debugging to be done, but I should be able to release a test version soon.
The main change will be a new watercolor painting effect which will replace the current Painting 1 effect that I'm no longer happy with. Here is an example of the new painting filter (click on image for full-size view):
Stay tuned :)
