The DSL model has been improved (with a new parser) and is now the unique model for Telosys. For now version 4.0.0 is only available with **Telosys-CLI** ### Models Since version 4.0.0 there is **only one type of model**: the **DSL model**. The DSL model has been enhanced to support all functionality previously available only in "db-model", thus the "db-model" is no longer useful. **Annotations** and **tags** are now usable at **entity** level. It is possible to **create a new DSL model from a database schema** (as for the previous "db-model") The DSL model has a new structure: \ each model is completely contained in a directory.\ It is more convenient to exchange and store models. See: Many new annotations have been added to enrich the DSL model. The DSL model offers now 55 annotations. See: ### Templates New objects and functions have been added in the generator context to make it easier to write templates. For example, a combination of new annotations and new functions simplifies SQL code generation. Among others, here are some new objects usable in the templates: \ $sql, $reference, $factory ### Databases The databases are now defined in a ".yaml" file : "**databases.yaml**" A "yaml" file is more convenient for editing, the yaml format being supported by most editors.
