Better align your long term support, security and enterprise systems planning goals with the rapid, feature-rich releases of Citrix Virtual Apps, Citrix Virtual Apps and Desktops, and Citrix Hypervisor.
Long Term Service Release
Long Term Service Releases (LTSR) are 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 Citrix Virtual Apps, Citrix Virtual Apps and Desktops, and Citrix Hypervisor 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.

1 Customer Success Services Program information
2 Customers with legacy Subscription Advantage have access to Current Releases for the duration of their contract, but are encouraged to upgrade to Customer Success Services.
3 Separate support contract is required for extended support. Citrix reserves the right to replace third party components with other components offering substantially similar or superior functionality where third party licenses to such components do not allow Citrix to fulfill LTSR support requirements.
4 Standard product lifecycle milestones information
5 Cumulative Updates will typically contain fixes only for Long Term Service Release sites. You will be asked to install relevant Cumulative Updates on Long Term Service Release sites.
6 Rapid release cycles allow you to add new features and all public bug fixes by upgrading to the next current release. You will be asked to upgrade Current Release sites to a newer release that includes relevant fixes as well as new features and functionality.
7 Customers on Long Term Service Releases will be asked to update to next Cumulative Update that contains the fix.
8 Customers on Current Releases might be asked to upgrade to next release that contains the fix.
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.
