When you use a Citrix environment and have a Citrix support contract this environment must comply with certain rules. It must be running the Current Release (CR) of the Citrix software or a Long-Term Service Release (LTSR). The CR is a version that is updated every 3 months and has all the new features and fixes in it. So, if you run this version you are always up to date and can use the newest features. You must also stay up to date within 6 months or else you will lose support (n-1 version).
