> n8n released version 3.0.0 as a beta on October 27, 2026, with the stable release planned for early December; it is a breaking-change release focused on reliability and security, self-hosted n8n now runs only on Docker, and the upgrade from 2.x cannot be rolled back, so n8n recommends running the Migration Report (version 2.39 or later) and taking a full backup first.

## What changed

- n8n 3.0.0 is available as a beta from October 27, 2026; the n8n blog says the stable release follows in early December and that 3.0 bundles breaking changes rather than new features.
- Self-hosted n8n now runs on Docker: installing with npm or npx n8n is no longer supported, which n8n says is partly because new security features depend on a container setup. Kubernetes and Helm deployments are not affected.
- Removed legacy nodes include Function, Function Item, Item Lists, Cron, Interval, the legacy OpenAI node and older AI Agent modes; Function maps to the Code node and Cron and Interval to the Schedule Trigger. Chat Hub is off by default and Import from URL is gone from the editor.
- Safer defaults: encryption key rotation is always on, Slack credentials require a signing secret, the SSRF block list is larger when SSRF protection is enabled, unverified community packages are off, and the default Code node timeout drops from 5 minutes to 1 minute.
- Runtime changes: in queue mode, manual executions always run on workers, and the in-memory binary data mode is removed in favour of the filesystem or S3 and other external storage.
- Upgrading is one way, with no rollback to 2.x. Instances on 2.39 or later have a Migration Report under Settings that lists affected workflows, auto-fixes many as new workflow versions, and exports a CSV. 2.x gets security and critical fixes for 12 months after stable; 1.x support ends December 31, 2026.

## Early verdict

Self-hosters on npm installs or using Function, Cron or legacy OpenAI nodes should run the Migration Report and test on a staging instance before moving to 3.x, since the upgrade cannot be reversed. (Basis: Based only on the changes and upgrade path n8n's announcement describes; we have not run the beta.)

## What we have not verified

- We did not install the beta or run the Migration Report ourselves.
- We read the announcement post only; the full per-change list is in n8n's breaking changes docs, which we did not review item by item.
- The exact stable release date is given only as early December.
