 The new table panel is very flexible, supporting both multiple modes for time series as well as for
 table, annotation and raw JSON data. It also provides date formating and value formating and coloring options.

 In the most simple mode you can turn time series to rows. This means you get a `Time`, `Metric` and a `Value` column.
 Where `Metric` is the name of the time series.

-For a detailed list and link to github issues for everything included in the 2.5 release please
+If you have Elasticsearch 2.x and Grafana 2.6 or above then you can use pipeline metric aggregations like
+**Moving Average** and **Derivative**. Elasticsearch pipeline metrics require another metric to be based on. Use the eye icon next to the metric
+to hide metrics from appearing in the graph. This is useful for metrics you only have in the query to be used
+in a pipeline metric.
