Gimp.app has been updated to v2.0.6. This update appears to update the actual Gimp application to v2.0.6 and there do not appear to be any other changes to the package itself. The changes in Gimp v2.0.6 are as follows:
“This is a bug-fix release in the stable 2.0 series. It fixes a couple of smaller problems and a crash that occurred with Pango-1.2 (but not with newer versions of Pango). This is the last release in the GIMP 2.0, tree which will be obsoleted by GIMP 2.2 very soon.”
