Better align your long term support, security and enterprise systems planning goals with the rapid, feature-rich releases of XenApp, XenDesktop, and XenServer.
Flexible service options enable predictable support
Citrix frequently delivers new features and functionality for XenApp and XenDesktop to keep your business competitive, streamline IT operations, enhance data security, and ensure your employees have access to their business resources from anywhere. We know you need to balance the rapid pace of innovation with long term planning to control the risk and expense of introducing change to your enterprise app and desktop delivery solution.
Citrix now provides servicing options to give you greater flexibility and choice in how you adopt new XenApp, XenDesktop, and XenServer functionality while giving you greater predictability for maintaining and managing the support of your environment.
Long Term Service Release
Long Term Service Releases (LTSR) is ideal for large enterprise production environments where you would prefer to retain the same base version for an extended period. With LTSR, you will have regular access to fixes typically void of new functionality for predictable on-going maintenance. With each LTSR comes new extended support timelines that let you plan ahead for upgrades at a pace that’s right for you and your organization.
Example: If you have adopted LTSR and report a new issue, but have not kept up with the different CU releases (CU1, CU2, CU3, CU4), Citrix will support your LTSR environment and work on a fix. However, you may be required to move to the latest available CU (CU4) to ensure that the issue is reproducible with the latest update. In addition, the official fix will be included as part of CU5, which will also include other fixes along with fixes previously released in CU1, CU2, CU3, and CU4.
Current Releases (CR) of XenApp, XenDesktop, and XenServer deliver the latest, most innovative app, desktop, and server virtualization features and functionality allowing you to stay on cutting edge technology and ahead of your competition. Ideal for agile environments where you can rapidly deliver the newest app, desktop, and server virtualization features, including both production and test environments. On-going support and maintenance for Current Releases is aligned with the frequent release cycles. Instead of managing new releases and patches independently, with Current Releases you can simply upgrade to the latest release which includes fixes and new functionality side-by-side.

9 General guidance, Citrix does not release product roadmaps publicly.
Now I can install and configure the latest XenApp, XenDesktop release in my development and test environment so I can thoroughly test the new features and provide Citrix with feedback before that feature reaches the Long Term Service Release. While my critical, production environment will only run a Long Term Service Release, this way I’ll have greater control and predictability over the environment’s stability and extended mainstream support.
