- XenServer 7.1 Long Term Service Release (LTSR)
The Long Term Service Release (LTSR) program for XenServer provides stability and long-term support for XenServer releases.
The XenServer product lifecycle strategy for Current Releases (CR) and Long Term Service Releases (LTSR) is described in https://www.citrix.com/support/product-lifecycle/milestones/xenserver.html.
A XenServer LTSR is currently available for Version 7.1. Cumulative Update 1 is the most recent update to the 7.1 LTSR. If you are new to the LTSR program and did not deploy the initial 7.1 LTSR release, there is no need for you to install it now. Instead, Citrix recommends that you begin with 7.1 Cumulative Update 1.
