This section lists current plans for removal of obsolete or deprecated components in the X.Org releases. As our releases are open source, users who continue to require these can find the source in previous releases and continue to use these, but the X.Org Foundation and its volunteers have decided the burden of continued maintenance and distribution in the core X11 releases outweighs the benefits of doing so. In some cases, this is simply because no one has volunteered to do continued maintenance, so if software is listed here that you need, you can contact email@example.com to volunteer to take over maintainership, either inside or outside of the Xorg release process.
The DPS code has been completely dropped as of X11R7.0.
The LBX extension is disabled by default now, although the code still ships in the 7.1 server. Compared to other solutions like NX and SSH, LBX has generally worse performance and worse security. It will be removed completely in 7.2; users are encouraged to migrate to better solutions.
