End Date of the Review Period

Reviews run for a minimum of one week. The outcome of the review is decided on this date. This is the last day to make comments or ask questions about this review.




EMF Diff/Merge is a diff/merge tool for models. Its main purpose is to help build higher-level tools that need to merge models based on consistency rules. GUI components and higher-level tools, such as support for modeling patterns and model synchronization, are also provided. Typical usages include model refactoring, iterative model transformations, bridges between models or modeling tools, collaborative modeling environments, or versioning systems.

This is the Photon release of EMF Diff/Merge. The main contributions are:

  • A more flexible UI (optional section, inter-view sync)
  • An improved extendibility (complete comparison behavior)
  • Some bug fixes (UI, Git integration)
  • A slight performance improvement (directed comparisons)
API Certification

The project leadership certifies that the APIs in this release are "Eclipse Quality".
