+### Fixed
+
+- Replace NodeSource repository with native Node.js packages on Debian >= 13 to fix deployment failure caused by NodeSource GPG key using SHA-1, [rejected by apt since 2026-02-01](https://github.com/nodesource/distributions/issues/1908)
+
+### Added
+
+- Add `migrate` playbook for one-time changes on existing servers; run `ansible-playbook opentermsarchive.deployment.migrate` before `deploy` when upgrading

+## Migrations
+
+Some updates require changes on existing servers before deploying. Run the `migrate` playbook before `deploy` when needed:
+
+```sh
+ansible-playbook opentermsarchive.deployment.migrate

 ## Playbook execution refinement
 
 Use [tags](https://docs.ansible.com/ansible/latest/user_guide/playbooks_tags.html) to refine playbook execution. Example commands:
