Note: This product is not compatible with the Community Version of Livecode

This Livecode plugin compares two stack files for the same Livecode project or an in-memory stack and a stack file and shows the differences between them.  It lists objects that were added or deleted, and changes in custom properties and scripts.  Scripts are displayed side by side with the differences color coded to represent lines that were added, deleted, or changed.
