2 days ago (January 28th) Citrix announced XenApp 7.5. Yes, that’s not a mistake. After XenDesktop 7 and 7.1 we are back to XenApp product line. But don’t worry. This is not the return to IMA. It’s still FMA (like XenDesktop).
Here is the announcement – Citrix XenApp 7.5 – New Generation of Windows App Delivery Designed for Mobility and Cloud.
