There are a number of significant changes in EMF 2.3 over EMF 2.2 which require mention.

This document will expand over time to include a complete list of such issues. Feel free to contribute!


New Features

The structure of Features in EMF 2.3 has changed since EMF 2.2. See EMF 2.3 New Features Migration Guide


JDOM vs. AST

JDT's JDOM API has been deprecated for many years and it does not support Java 5.0 syntax at all. As of EMF 2.3, we've migrated to use JDT's AST API instead, which supports all Java syntax. It should now be the default for the "Facade Helper Class" property in the GenModel:

So if your GenModel has this set to the older JDOMFacadeHelper, change it to the above value (or better yet, just use the circled button above to set it back to its default value which will be the above for EMF 2.3.0).


Standalone Zip

The Standalone Zip bundle is no longer being offered as a download option as of EMF 2.3. Why? See EMF 2.3: Standalone Zip Removed and bug 191837 for details.
