n8n 2.48.2 Fixes Public API Edits to Read-Only Credential Nodes

n8n released version 2.48.2 on November 12, 2026. The release contains only bug fixes, and the most notable change affects the Public API. The API now rejects requests that try to edit read-only credential nodes, which tightens how automated tools can modify workflow credentials.

The release also includes two editor fixes. Animated node borders now have aligned corners, a visual correction on the workflow canvas. Agent tabs also stay available when users start new drafts, so builders keep access to them in that flow.

Why it matters

Read-only credential nodes are meant to stay protected, so an API that rejects edits to them supports tighter access control. Teams that script or integrate with n8n’s Public API should treat this as a change in behavior. The editor fixes are smaller, but they improve the everyday experience of building workflows.

What to do

If you self-host n8n, review the release notes and plan an upgrade to 2.48.2. Check any scripts or integrations that call the Public API to confirm they do not depend on editing read-only credential nodes. For cloud availability and rollout timing, confirm the details on n8n’s website before changing your setup.
