=== Component Versions
You have access to information about the version of your Processors, Controller Services, and Reporting Tasks.
This is especially useful when you are working within a clustered environment with multiple NiFi instances running
different versions of a component or if you have upgraded to a newer version of a processor. The Add Processor,
Add Controller Service, and Add Reporting Task dialogs include a column identifying the component version, as well
as the name of the component, the organization or group that created the component, and the NAR bundle that contains
the processor. Each component displayed on the canvas also contains this information.
==== Sorting and Filtering Components
When you are adding a component, you can filter based on originating source or version number.
To sort based on version, click the version column to display in ascending or descending version order.
To filter based on source group, click the source drop-down in the upper left of your Add Component dialog,
and select the source group you want to view.
==== Changing Component Versions
To change a component version, perform the following steps.
. Right-click the component on the canvas to display configuration options.
. Select Change version.
. In the Component Version dialog, select the version you want to run from the Version drop-down menu.

When you are configuring a component, you can also view information about version dependencies.
. Right-click your component and select Configure to display the Configure dialog for your component.
. Click the Properties tab.
. Click the information icon to view any version dependency information.
