+0.9.1 - `2021-06-28`
+~~~~~~~~~~~~~~~~~~~~
+
+This release introduces a breaking change (PR `#3646 <https://github.com/Netflix/lemur/pull/3646>`_) to the following API endpoint: 
+
+- `POST /certificates/1/update/notify <https://lemur.readthedocs.io/en/latest/developer/index.html#lemur.certificates.views.Certificates.post>`_
+
+The endpoint is now:
+
+- `POST /certificates/1/update/switches <https://lemur.readthedocs.io/en/latest/developer/index.html#lemur.certificates.views.Certificates.post>`_
+
+The new endpoint honors the existing `notify` request parameter, and additionally accepts a new `rotation` parameter. 
+As a result of this change, the certificate table view now includes rotation switches and filtering by rotation status.
+
+

+
+- ACME:
+    - New celery task to prevent duplicate certificates from being autorotated

+    - CSRF protection is added to OAuth2.0

+    - New revocation notification
+- Plugins:
