New Post: Upgrade 1.3 to 2.0/2.1 problem

Dirk, the 1.3 release is from before Composite C1 became open source and we introduced a great deal of changes between 1.3 and 2.0 (the first open source version) in order to get the public source code as readable and nice to use as time would permit.

You can get in contact with us if you are interested in us helping you upgrading. If you still have a active support agreement on your 1.3 version, the upgrade is covered here. Get in touch with me at maw@composite.net if we should help out here.
