Version 1.3.0 of VIATRA provides compatibility with the Neon simultaneous release, and also provides a few major features:
- Query by Example: A component to derive graph patterns based on the current selection. It is expected that using this feature helps to understand the basics of the pattern language and/or the structure of the metamodel.
- Updated query and transformation development environment: The query development environment was updated to accommodate the various features developed over the years, and provide a set of views to help the query and transformation development.
- Incremental Transformation Debugger: To monitor how a VIATRA transformation executes, a debugger prototype is provided. In the current version, only transformations executed in the same Eclipse instance are supported.
Furthermore, a large number of other issues and features were added to ensure VIATRA works seamlessly with a wide range of models.
