+### Fixed
+
+- Previously we had a bug that could lead to missing certificates ([#844]).
+
+  This could be the case when you specified multiple CAs in your SecretClass.
+  We now correctly handle multiple certificates in this cases.
+  See [this GitHub issue](https://github.com/stackabletech/issues/issues/764) for details
