n8n version 2.37.0 arrived on August 25, 2026, bringing a hefty batch of improvements for self-hosted users. This release focuses heavily on AI agent reliability, workflow editing polish, and under-the-hood performance gains. Below, we break down the most notable changes by theme.
Bug Fixes and Core Stability
This update squashes dozens of bugs across the core engine and editor. Highlights include fixing the Agent Node to show the reason a prompt-source option is disabled, resolving AI Builder autosave and publish event issues, and improving the Anthropic Chat Model Node by updating its default model to Claude Sonnet 5. Core fixes range from handling multipart forms with empty file inputs gracefully to avoiding unnecessary restarts of slow task runners, and from properly validating OAuth2 token audiences to reconciling license auto-renewal on startup. The editor also received many corrections: it now prevents stale credentials from appearing when switching, groups output panel warnings for better usability, and keeps agent preview messages right-aligned, among many other UI refinements. These changes collectively make self-hosted n8n instances more stable and predictable.
New Features and Integrations
New capabilities in 2.37.0 include Slack Agent view support, streaming for Message an Agent workflows, and the ability to configure inputs for workflows used as tools by AI agents. The AI Builder can now show why unsupported workflows cannot run within agents, and it displays tool failures in session traces. On the integration front, the Grist Node gains an upsert operation, the Microsoft SharePoint Node registers version 2 as the default, and the Typeform Node allows custom OAuth2 scopes. Additionally, the API now includes endpoints for managing custom roles and role-mapping rules, plus new filters for listing executions. The editor introduces a new Combobox component, a stop execution button in the node details view, and improved pagination controls. Self-hosted admins will also appreciate the pointer-compressed Docker image variant and an install script that shows live pull progress.
Performance Enhancements
Two performance improvements ship in this release: the core now hydrates Instance AI history trees only for the requested page, and it skips reading run data when saving execution progress. Both changes reduce unnecessary data processing, leading to faster load times and less overhead for long-running workflows—especially beneficial for self-hosted deployments with limited resources.
