Sparkr updates may occur automatically through Atlassian’s Universal Plugin Manager (UPM). For more information on updating apps, see Atlassian’s Guide.
Larger Sparkr releases may require your Jira administrator to manually update the app through the Universal Plugin Manager (UPM). To do so, you must navigate to Jira Settings > Apps > Manage apps and expand the Sparkr app listing under your installed apps.
An update button should be visible and when clicked will update Sparkr to the available version.
