Introduction
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 Monday, Dec 19th, version 3.5.99.3 of nx-libs has been released [1].
This release brings another major backport of libNX_X11 (to the status of X.org's libX11 1.6.4, i.e. latest HEAD) and also a major backport of the xtrans library (status of latest HEAD at X.org, as well). This big chunk of work has again been performed by Ulrich Sibiller. Thanks for your work on this.
This release is also the first version of nx-libs (v3) that has dropped nxcompext as shared library. We discovered that shipping nxcompext as shared library is a big design flaw as it has to be built against header files private to the Xserver (namely, dix.h). Conclusively, code from nxcompext was moved into the nxagent DDX [2].
Furthermore, we worked again and again on cleaning up the code base. We dropped various files from the Xserver code shipped in nx-libs and various compilier warnings have been amended.
In the upstream ChangeLog you will find some more items around code clean-ups and .deb packaging, see the diff [3] on the ChangeLog file for details.
A very special and massive thanks to all major contributors, namely Ulrich Sibiller, Mihai Moldovan and Vadim Troshchinskiy. Well done!!! Also a special thanks to Vadim Troshchinskiy for fixing some regressions in nxcomp introduced by the Unix socketeering support.

Known Issues from 3.5.99.2 (solved in 3.5.99.3)
This version of nx-libs now works fine again with LDFLAGS / CFLAGS having the -pie / -fPIE hardening flags set.
Binary Builds
You can obtain binary builds of nx-libs for Debian (jessie, stretch, unstable) and Ubuntu (trusty, xenial) via these apt-URLs:
- Debian:
deb http://packages.arctica-project.org/debian {jessie,stretch,sid} main - Ubuntu:
