The Simple persistence for Java project has announced the release of version 1.4.0. "Basic index handling was added. findSingle() methods were added for convenience, which return exactly one object or null. View selects were added, which can be used to select attributes that may span multiple objects. These can be used to present lists and reports to users, and can reduce the number of queries required to generate lists/reports significantly (versus using objects to get the specific attributes). The returned objects in case of views are Maps, not specific objects, so they can only be used for presentation."
