n8n 3.0.0 released with bug fixes across core, API, and AI agent features
n8n published release 3.0.0 on 2026-10-27 on its GitHub releases page. The release notes list a large set of bug fixes covering the core workflow engine, the public API, AI Assistant and Agent nodes, binary data handling, and OAuth2 credential scopes.
Why it matters
A major version number means the release may include breaking changes, so existing n8n workflows and self-hosted instances should be checked before upgrading. Several fixes change behaviour for agent credentials, execution redaction, and API credential fields that automations may depend on.
Who should care
Self-hosted n8n operators, automation builders, agencies maintaining client workflows, and developers using n8n's public API or AI Agent nodes.
