# Changelog

### v4.0.0

* Projects. Models, published ontologies and schemas, files, database connections, prefixes, and design history belong to a project. Transformers and plugins stay shared across the installation. See [Projects](/EGeX4aTAJLlpg9Hh8kfl/graph.build-studio/projects.md).
* Project access. A project is Private, Public, or shared with named people. Models and published files keep their own permissions. Modular ontologies can be shared on their own.
* AI Assistant. Chat answers questions, including `/docs` questions against this documentation. Generate builds or edits the open design, including property graph schemas and mappings. See [AI Assistant](/EGeX4aTAJLlpg9Hh8kfl/graph.build-studio/ai-assistant.md).
* Studio Settings for the assistant: provider, daily token limit, guardrails, how much source data is sent, and optional personal API keys.
* Backup and export. A Super Admin can export every project as a `.gbs` file, or download a backup that can restore the deployment. See [Backup and export](/EGeX4aTAJLlpg9Hh8kfl/graph.build-studio/backup-and-export.md).
* MCP server. An AI client can explore ontologies, read the projects you can open, and edit or create ontology designs. See [MCP Server](/EGeX4aTAJLlpg9Hh8kfl/graph.build-studio/mcp-server.md).
* Imports land in the project you have open. A model name that is already used in that project is rejected.
* Home lists use table and card view. Git history for a model or published ontology opens from the project page.
