Due to popular demand, ImageMagick has been upgraded from 6.2 to the latest release, 6.4. Incompatible API differences exist between the two versions. Old libraries from 6.2 remain on the server to avoid breaking applications, such as rmagick, built around the ImageMagick 6.2 API.
ImageMagick 6.4 now available
Hey thanks! Now Gallery won’t complain about imagemagick being old and a security problem. 😉
