v3.4.0

What's Changed

• Enhancements to identifiers. The format for identifiers in Concerto (i.e. the name of Concepts, Properties etc.) has been relaxed to allow values such as false, true and null. The format is now consistently applied too, in particular, it is enforced in the JS API and JSON AST.
• JSON Schema generation from Concerto models will now include an anyOf declaration for types with multiple subtypes
• UML output (to Mermaid and PlantUML) for models now supports optional generation of Composition and Aggregation relationships in diagrams. UML output can also omit the base Concerto types (such as Concept).

Access the new options via the API parameters or CLI flags.

$ concerto compile --target mermaid --model model.cto --showCompositionRelationships --hideBaseModel
