[Arctica Project] Release of nx-libs (version


NX is a software suite which implements very efficient compression of the X11 protocol. This increases performance when using X applications over a network, especially a slow one.

NX (v3) has been originally developed by NoMachine and has been Free Software ever since. Since NoMachine obsoleted NX (v3) some time back in 2013/2014, the maintenance has been continued by a versatile group of developers. The work on NX (v3) is being continued under the project name "nx-libs".

Release Announcement

On Thursday, Oct 13th, version of nx-libs has been released [1].

This release brings a major backport of libNX_X11 to the status of libX11 1.3.4 (as provided by X.org). On top of that, all CVE fixes provided for libX11 by the Debian X11 Strike Force and the Debian LTS team got cherry-picked to libNX_X11, too. This big chunk of work has been performed by Ulrich Sibiller and there is more to come. We currently have a pull request pending review that backports more commits from libX11 (bumping the status of libNX_X11 to the state of libX11 1.6.4, which is the current HEAD on the X.org Git site).

Another big clean-up performed by Ulrich is the split-up of XKB code which got symlinked between libNX_X11 and nx-X11/programs/Xserver. This brings in some code duplications but allows maintaing the nxagent Xserver code and the libNX_X11 code separately.

In the upstream ChangeLog you will find some more items around code clean-ups and .deb packaging, see the diff [2] on the ChangeLog file for details.

So for this releas, a very special and massive thanks goes to Ulrich Sibiller!!! Well done!!!
