Appendix A. Flow Definition Language 1.0 to 2.0 Mappings
Prev

The flow definition language has changed since the 1.0 release. This is a listing of the language elements in the 1.0 release, and how they map to elements in the 2.0 release. While most of the changes are semantic, there are a few structural changes. Please see the upgrade guide for more details about changes between Web Flow 1.0 and 2.0.
