  This topic describes app revisions and provides procedures for working with them. 
  
  For additional information, see [Revisions](http://v3-apidocs.cloudfoundry.org/version/release-candidate/#revisions) in the Cloud Foundry API (CAPI) documentation. 
  
  <p class="note"><strong>Note:</strong> CAPI v3 is the recommended API version for revisions. While revisions work with CAPI v2, there are several inconsistencies. For example, revision descriptions for apps with multiple processes may be inaccurate because CAPI v2 does not support apps with multiple processes. Additionally, pushing an app for the first time with revisions in CAPI v2 creates two revisions.</p>
  
  
  ## <a id="overview"></a> Overview
  
  A revision represents code and configuration used by an app at a specific time. It is a CAPI object that can contain references to a droplet, custom start command, and environment variables. The most recent revision for a running app represents code and configuration currently running in <%= vars.platform_name %>.
  
  Some use cases for revisions include:
  
  * **Viewing revisions for an app:** This can help you understand how your app has changed over time. 
  
  * **Rolling back to a previous revision:** This allows you to deploy a version of the app that you had running previously without needing to track that previous state yourself or have multiple apps running. When you create a deployment and reference a revision, the revision deploys as the current version of your app.
  
  ### <a id="events"></a> Events that Trigger Revisions
  
  Revisions are generated automatically through these events:
  
  * A new droplet is created for an app.
  * An app's environment variables are changed.
  * The custom start command for an app is added or changed.
  * An app rolls back to a prior revision.
  
  By default, CAPI retains a maximum of 100 revisions per app.
  
  ### <a id="revision-description"></a> Revision Descriptions
  
  Each revision includes a description of what changed in your app at the time the revision was created. The description includes one or more of these descriptions:
  
  * `Process type removed`
  * `New process type added`
