What the article says
n8n 3.0.0 entered beta on October 27, 2026, with the stable release planned for early December. The release aims at reliability, stability and security; because it contains breaking changes, it carries a major version bump. Moving to the 3.x line is one-way: rolling back to 2.x is not possible.
Changes include manual executions always running on workers, removal of the in-memory binary data mode, a Code node default timeout cut from 5 to 1 minute, and Cron and Interval nodes replaced by the Schedule Trigger. On security, encryption key rotation is always on, Slack requires a signing secret, the SSRF block list is larger and unverified community packages are off by default. Docker becomes mandatory for self-hosting. A Migration Report (version 2.39 or later) helps identify affected workflows; credentials and execution history carry over. The 2.x line receives security fixes for 12 months and support for 1.x ends on December 31, 2026.
