You can see which version of Grouper is running in the UI in the configure screen
This output uses a JEXL expression in the text config (grouper.text.en.us.properties)
configurationIndexSubtitle = System settings and wizards to setup the registry. Grouper version: ${edu.internet2.middleware.grouper.misc.GrouperVersion.grouperVersion()}
The JEXL expression can be used in other text properties. In the following example, the version is added to the institution name:
institutionName.elConfig = Institute of Higher Education (Grouper ${edu.internet2.middleware.grouper.misc.GrouperVersion.grouperVersion()})
***NOTE: institutionName is used in multiple locations so your version number will show up as the title for your logo, in your footer, and on the home page as pictured above
