Upgrade Information ============================================ !!! Warning: Classes SnapshotManager, ToManyListDataSource, RelationshipDataSource, FlattenedRelationshipDeleteQuery, FlattenedRelationshipInsertQuery were removed from Cayenne, since maintaining them in a deprecated state wasn't possible. - Upgrading Project XML Files: Opening a 1.0 projects in CayenneModeler would display an upgrade dialog. Select "Yes" button to perform the upgrade. Note that upgrading a project to 1.1 will make it unusable with earlier versions of Cayenne. - Clean Recompile: Cayenne 1.1 introduces a few API changes. Most of them are done to the backend and should not affect the applications written with the earlier versions. However it is a good idea to perform a clean compilation of all Java code that relies on Cayenne. Updating calls to deprecated methods is a good idea as well. For the latest upgrade instructions see the Use Guide included in Cayenne download: [cayenne_install_dir]/doc/userguide/install/upgrade.html For the list of new features in 1.1 see another Use Guide chapter: [cayenne_install_dir]/doc/userguide/introduction/whats-new.html
