+## v1.7 [unreleased]
+
+### Release Notes
+
+- The `cassandra` input plugin has been deprecated in favor of the `jolokia2`
+  input plugin which is much more configurable and more performant.  There is
+  an [example configuration](./plugins/inputs/jolokia2/examples) to help you
+  get started.
+
+- For plugins supporting TLS, you can now specify the certificate and keys
+  using `tls_ca`, `tls_cert`, `tls_key`.  These options behave the same as
+  the, now deprecated, `ssl` forms.
