 ### Release Notes
+- **breaking change** `plugins` have been renamed to `inputs`. This was done because
+`plugins` is too generic, as there are now also "output plugins", and will likely
+be "aggregator plugins" and "filter plugins" in the future. Additionally,
+`inputs/` and `outputs/` directories have been placed in the root-level `plugins/`
+directory.
 - **breaking change** the `io` plugin has been renamed `diskio`
 - **breaking change** Plugin measurements aggregated into a single measurement.
 - **breaking change** `jolokia` plugin: must use global tag/drop/pass parameters
 for configuration.
-- **breaking change** `procstat` plugin has `*cpu*` fields renamed to
