This is the first LTS release of xpra. It will be supported for a
minimum of 18 months and is therefore a good choice for distributions
with longer release cycles.
Another LTS release will overlap with this one, sometime next year.

This being the first Long Term Support (LTS) release, many of the
changes are in fact clean-ups or changes which allow us to provide
better security and control over the application's deployment.

In particular, we remove older codecs (python-webm), add support for
new alternatives in the packet layer (lzo compression, yaml packet
encoder) and allow each and every codec to be disabled: this applies
to all the parsers, compressors, picture encoders and decoders - of
which there are many.
Should there be another security issue with lz4 / lzo (see "​The 20
Year Old Bug that Went to Mars") or even zlib (ie: ​CVE-2005-2096),
then the application can be secured using configuration changes only,
without having to wait for a security update. This is most important
for platforms which do not have a real native package manager for
libraries (MS Windows and Mac OSX).

We no longer ship static codecs for any RPM distribution (centos /
Fedora), instead we maintain our own private RPM builds of the media
libraries (x264, ffmpeg and for some older versions also libvpx and
libwebp), which we will keep up to date independently of the xpra
packages. (and certainly more up to date than any other repositories
we are aware of)
Users of the yum repositories will get their security updates as soon
as new versions are available instead of just when a newer version of
xpra is released.
All the RPM specfiles and SRPMS are also available for those who wish
to do it all themselves. (thanks to Matthew Gyurgyik)

There is also a new integrated bug reporting tool, support for lzo
compression, and many performance optimizations.
One major new feature is the automatic display selection, which means
that you no longer need to choose a free X11 display (thanks to Benoit

This will be the last release to support python 2.5 and older, libav,
old versions of GTK, etc..
