Cayenne 4.1 Milestone 1 Released¶
Oct 14, 2017
Apache Cayenne team is glad to announce the first milestone release of Cayenne 4.1. This is a development release that introduces a number of nice new major features:
- New field-based data objects (see CAY-2330), that are much faster to read and write, while significantly reducing the app memory footprint.
- Dependency-free Cayenne core. No more velocity or commons-collections compile dependencies. Only "slf4j-api" is required in the base config.
- New extensible project XML structure. In M1 we are using this to store comments for entities, attributes and relationships. Future milestones will add storing configuration for cdbimport and cgen.
Cayenne can be downloaded from here.
