 * **Rollout** - Indicates the percentage of users that are elligble to receive this update. This property will only be displayed for releases that have been tagged with a non-empty rollout value, and can only ever be present on the latest release within each deployment.
 
+* **Disabled** - Indicates whether the release has been marked as disabled or not, and therefore, is acquirable by end users. This property will only be displayed for releases that are actually disabled.

 When the metrics cell reports `No installs recorded`, that indicates that the server hasn't seen any activity for this release. This could either be because it precluded the plugin versions that included telemetry support, or no end-users have synchronized with the CodePush server yet. As soon as an install happens, you will begin to see metrics populate in the CLI for the release.
