TL;DR

This update resolves critical stability issues within the Code Node and webhook execution handling.

Fixes Worth Knowing

• Code Node: Restored functionality for external modules (third-party JavaScript libraries) when enabled in v1.x.
• Webhooks: Fixed an issue where webhook execution promises would not settle during early errors, improving reliability of trigger responses.

TL;DR

This update focuses on improving AI Agent stability, refining MCP (Model Context Protocol) workflow executions, and resolving critical credential and UI bugs.

New

• Introduced an experimental credential selection for n8n Credits.

Fixes Worth Knowing

• AI & Agents: Fixed AI assistant quota error visibility, preserved node aliases in tool variants, and improved AI Agent node response simplification.
• MCP: Now requires execution mode for MCP workflow executions and supports N8N_MCP_BASE_URL for split-hostname OAuth deployments.
• Core & UI: Fixed dropdown width issues in the UI, corrected SES (Amazon Simple Email Service) request signing, and improved end-user credential validation.
• Integrations: Restored ASCII simplified property keys for older versions of the Notion node.

TL;DR

The n8n editor now includes a toggle to directly access Message Communication Protocol (MCP) settings on workflow cards, simplifying debugging and configuration.

New

• Editor MCP Access: A toggle has been added to workflow cards for quick access to MCP settings (network communication details).

TL;DR

The latest update improves n8n’s (workflow automation tool) reliability and usability by fixing issues with the command bar and leader election.

Fixes Worth Knowing

• The command bar now correctly finds workflows.
• Leader election now emits the leader-takeover event as expected, improving cluster stability.
• External secrets input styling in the editor has been adjusted.

TL;DR

The AI Builder integration (a no-code automation tool) is more reliable with improved handling of complex workflows and static parameter validation.

Fixes Worth Knowing

• AI Builder: Resolved an issue with stream recursion limits and static parameter validation, preventing errors when using the AI Builder node in workflows.

TL;DR

n8n now supports larger JSON data downloads from the editor and includes numerous bug fixes improving reliability across many nodes and core functionality.

Fixes Worth Knowing

Many nodes received fixes, including AWS S3 (handling periods in bucket names), Email Trigger (UTF-8 attachments, connection issues), FTP (preventing infinite loops), and HTTP Request (TCP socket errors). Core improvements address BigInt serialization, file path access restrictions, and crash logging. Several credential and key formatting issues were also resolved.

New

The editor now has a "Download" button for large JSON data. Additionally, parallel processing is enabled for multiple queue nodes, potentially improving workflow speed. Support for not requiring SMTP auth with user management has been added.
