Developing for Ubercart 1.x

The Ubercart 1.x API was fleshed out during the initial development, alpha, and beta phases from September 2006 to January 2008. Minor changes were made during the release candidate cycle leading up to the release of Ubercart 1.0 on June 4, 2008. These documents were never completed, and other documentation was posted at and throughout our forums. Here's to next release having better docs and more inline documentation!
