What's New
1.4.0 renames Folders to Projects, adds Anthropic tool calling and MCP SSE, and deprecates AUTO_LOGIN.
Breaking Changes
- The structural rename from Folders to Projects may break integrations, bookmarks, or API/UI references that still use folder-based paths.
New Features
- Anthropic tool-calling model lists and filters were updated.
- MCP SSE can now be configured from the frontend.
- A new EmbeddingModelComponent generates embeddings.
- Composio Slack and Google Calendar components were added.
- A new tool-mode dialog/UI and serverless flow execution were introduced.
Improvements
- AUTO_LOGIN now emits a deprecation warning.
- Component utility functions support dynamic input actions.
- Community interaction tracking gained observable UX.
- Dropdowns can add new values when absent from the options list.
- Combine Text is deprecated and templates were updated.
Upgrade Notes
Expect the Folders-to-Projects rename to affect UI/API references and saved folder paths, so update integrations accordingly. Migrate away from AUTO_LOGIN and Combine Text before removal, and retest flows that use those features. Validate MCP/SSE and Anthropic tool-calling settings after upgrading.
