-## 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.
