Incremental Updates for Citrix
Since Citrix have increased the pace of XenApp and XenDesktop updates, the new LTSR (Long Term Service Release) has been set at version 7.6. For some organisations, this allows them to set at a particular release and not worry about feature updates (even if that is a challenge for techs who always want the latest feature).
One of the issues is that it's become less obvious when the next LTSR is due. Citrix have issued that the next release will be in Q3 2017.
