 Changelog
 =========
 
+- 2022.11.24
+  - remove zope to fix compatibility with Certbot 2.x (Fixes #19)
+    As a reminder, Certbot will default to issuing ECDSA certificates from release 2.0.0.
+    If you update from a prior certbot release, run the plugin once manually. You will be prompted
+    to update RSA key type to ECDSA.
+
 - 2022.05.15
   - Added capability to handle multiple domain validations #16
