Upgrade Information ============================================ 1. General Upgrade Advise: - 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. - Upgrading between 1.1 milestones will not display an upgrade dialog, however on save mapping may slightly change, as the format evolved up till Beta. - 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 also a very good idea. 2. General Warning: Classes SnapshotManager, ToManyListDataSource, RelationshipDataSource, FlattenedRelationshipDeleteQuery, FlattenedRelationshipInsertQuery and a few others were removed from Cayenne, since maintaining them in a deprecated state wasn't possible.
