n8n version 2.33.0, released on July 28, 2026, delivers a massive set of updates focusing on the AI Builder, core stability, editor refinements, and new node functionalities. This release includes over 100 fixes and features designed to improve the self-hosted automation experience.
AI Builder Gets Smarter and More Robust
The AI Builder receives significant attention with fixes that ensure smoother workflow verification, better language retention in assistant replies, and improved tool handling. Channels like Linear and Telegram now have properly enabled configuration dropdowns. Slack setup labels are more precise about access tokens, and MCP connection failures are treated as non-blocking, so agents continue operating even if some tools are unavailable. Preview chat links have been fixed, and the builder now provisions agent prerequisites before delegating builds. Additionally, the AI Builder now supports verified community nodes as agent tools, formats Zod errors into clearer toast messages, and introduces a single preview chat and trace modal. Agent session records now go directly to the session chat, and the builder supports execution scenarios for first-class agents in evaluations. Tool names and UX have been tidied up, and a “Fix with Assistant” feature helps troubleshoot failed agent preview tools.
Core Platform Stabilized and Extended
The core engine sees numerous reliability improvements. The scheduler now accepts 5-field cron expressions, and concurrent instance startups are prevented from racing database migrations. Execution data loading is avoided during credentials security audits, and various OAuth and MCP-related fixes ensure proper token handling and metadata advertising. Data table nodes now fail fast with clear errors when referencing missing tables, and workflow deletions are rejected while unpublishing is in progress. Sub-workflow execution records are redacted per their own policy, and secret values are sanitized before persisting to agent memory. S3 object paths now use strict RFC 3986 encoding for signing. On the feature side, admin-managed instance credentials and a new workflow review system are introduced. The review system includes endpoints for listing version history, submitting reviews, and tracking open/closed counts. New external workflow hooks (deactivate) and telemetry events for agent publishing and builder capabilities are added. Workflow lifecycle hooks now include the acting user identity. The AI Assistant configuration is revamped with a redesigned instance settings page. Other additions: support for legacy sub-workflow dependencies in package exports, auto-inclusion of sub-workflows in exports, validation of missing node types on import, and the ability to configure the scheduler’s dead-letter threshold via N8N_SCHEDULER_MAX_ATTEMPTS. OpenTelemetry configuration now has public API endpoints, and agent run spans are emitted through the OTel module.
Editor and User Interface Refinements
Numerous editor fixes enhance usability: LDAP users can now configure 2FA; the sidebar width is clamped when expanding; node creator search is debounced; quick connect no longer appears for non-main auth fields; copy invite links work in Safari; and HTML strings in table names are escaped. Agent channel credential setup is restored, and the NDV panel’s horizontal scrolling and node hints are now more reliable. The editor also introduces a workflow review submission flow, a modal to see all accessible projects, and improved OpenTelemetry settings migration. New components like N8nStatusDot and improvements to the MCP settings view round out the UI updates.
Node Improvements and New Integrations
Many individual nodes received fixes and enhancements: Airtable now supports matching array fields in update operations; Baserow formats date filters for its API; Cohere chat is routed through the v2 endpoint; DeepSeek preserves reasoning content during tool calls; and the HTTP Request node includes error bodies in continueOnFail mode. The Form Trigger node properly handles quotes in names, and the Microsoft Teams node respects server-side limits in getAll operations. A new Microsoft Excel (SharePoint) node allows working with Excel workbooks in SharePoint document libraries. Custom OAuth scopes are now allowed for Microsoft Azure Monitor, Dynamics, Graph Security, Azure Storage, and all Google credentials. The AWS Bedrock Chat Model node surfaces inference-profile models. Other node-level fixes include the AMQP Trigger capping concurrent executions, MCP Client Tool sessions closing properly, and the Wikipedia Tool surfacing errors as actionable node errors. Database nodes now serialize dates and route binary columns correctly, and array reversal now returns the reversed array as expected.
Performance also gets a boost with a skipped allowed-methods lookup on successful production webhook requests.
