langflow-ai/langflowMay 8, 2025 → May 19, 202511 days between releases
What's New
1.4.2 adds breaking-change UX, BigQuery SQL, bulk flow/file actions, and Desktop support over 1.4.1.
New Features
- A modal now guides users through breaking changes and refactors how dismissed updates are tracked.
- A custom component can execute Google BigQuery SQL queries.
- Flows and files can be downloaded or deleted in bulk from the UI.
- The Python REPL component accepts multiline input.
- Langflow Desktop is now supported.
Improvements
- Flow settings enforce a minimum name length and provide default naming.
- URL and API request components can send user-agent headers, with a default user agent available.
- npx-based MCP commands check for Node.js before running.
- Endpoint basic examples are cached to speed up the interface.
- Dismissed-update handling was refactored as part of the new breaking-change flow.
Upgrade Notes
No explicit migration steps or breaking API changes are listed for 1.4.2, but review the new breaking-change modal and any dismissed-update state after upgrading. If you use npx-based MCP commands, ensure Node.js is installed; BigQuery usage requires appropriate Google Cloud credentials. Flow name validation may reject empty or too-short names.
