 ### Release Notes
 - The -test flag will now only output 2 collections for plugins that need it
+- There is a new agent configuration option: `flush_interval`. This option tells
+Telegraf how often to flush data to InfluxDB and other output sinks. For example,
+users can set `interval = "2s"` and `flush_interval = "60s"` for Telegraf to
+collect data every 2 seconds, and flush every 60 seconds.
+- `precision` and `utc` are no longer valid agent config values. `precision` has
+moved to the `influxdb` output config, where it will continue to default to "s"
+- debug and test output will now print the raw line-protocol string
