# Configuration Revisions
<a name="configurations-configuration-id-revisions"></a>

This is a collection of configuration revisions. To keep track of the changes you make to your configuration, you can create configuration revisions. For more information, see [Configuration](https://docs.aws.amazon.com//amazon-mq/latest/developer-guide/configuration.html) in the Amazon MQ Developer Guide.

**Important**  
Making changes to a configuration does not apply the changes to the broker immediately. To apply your changes, you must wait for the next maintenance window or reboot the broker.
