 This changelog documents user-relevant changes to the GitHub runner charm.
 
+## 2026-04-17
+
+- Added `token-secret-id` and `openstack-clouds-yaml-secret-id` configuration options, allowing the GitHub token and OpenStack `clouds.yaml` to be supplied through Juju user secrets. When set, these take precedence over the plaintext `token` and `openstack-clouds-yaml` options, which remain supported as a compatibility fallback.
+
 ## 2026-04-13
 
 - Fixed Juju secrets not picking up new revisions. The charm now uses `refresh=True` when reading secret contents, ensuring it always retrieves the latest revision instead of a cached one.
