The ArtRage 2.5 Plus edition CD contains ArtRage 2.5 Full edition, so even if you have purchased the downloadable version of ArtRage, you have the latest version - the same version that is on the CD.
ArtRage 2.5 Plus edition includes a glossy 80 page full colour manual, and additional content on the CD.
As the cost of producing a CD and glossy manual, and shipping them is such a large proportion of the production costs of ArtRage 2.5 Plus edition, we're not currently offering upgrade or 'cross-grade' pricing on ArtRage 2.5 Plus edition.
