n8n n8n@2.39.8 released on 18-09-2026
n8n n8n@2.39.8 is out now. It repairs data-encryption keys that were stored as the raw instance key, sweeps parent executions that remained parked after sub-executions finished, and fixes blank workflow previews in the AI Assistant, reducing decryption failures, stuck workflows and empty previews for affected users.
See the n8n GitHub release notes for full details, commits and issue references.
What’s in this release
- Repair data-encryption keys stored as the raw instance key — prevents decryption failures where keys were saved in the wrong form.
- Sweep parents parked on a finished sub-execution — cleans up parent executions that were left waiting and can free stuck workflows and resources.
- Fix blank workflow previews in the AI Assistant — restores preview rendering; if you saw empty previews before, refresh the editor after updating.
Upgrade notes
- If you suspect encrypted data access problems, upgrade to 2.39.8; the release repairs keys automatically in most cases. After updating, check your instance key/storage and review logs for any key-related errors.
- No specific rollback instructions are included in the release; if you need to revert, follow your usual rollback procedure and restore from known-good backups of the instance and database.
Let us know if the upgrade resolved your issue or changed how workflows behave — share comments on your experience so others can see what worked.
