On the prospect of future versions, the X.org website states:<ref>{{cite web|url=https://www.x.org/wiki/Releases/7.8 |title=Releases/7.8 |publisher=X.org |access-date=6 May 2014}}</ref>

{{Blockquote|X.Org continues to develop and release the X Window System software components.

These are released individually as each component is ready, without waiting for a overall X Window System "katamari" release schedule - see the individual X.Org releases directory for downloads, and the xorg-announce archives or git repositories for details on included changes.

No release plan for a X11R7.8 rollup katamari release has been proposed.}}
