JIRA Service Desk 1.2.5 Release Notes
Atlassian Analytics plugin bundled
JIRA Service Desk 1.2.5 bundles the Atlassian Analytics plugin, which is used to collect analytics information from Atlassian products. After upgrading to 1.2.5, you will see a banner that explains how data collection is set up and where you can change it. The banner will only be displayed for JIRA system administrators, i.e. users with the JIRA System Administrators permission.
In summary, this plugin introduces a new setting for collecting data and removes the existing analytics options from JIRA and JIRA Service Desk.
For information about data collection, see How JIRA Service Desk Collects Analytics.
