     57=== 0.16.0 Release ===
     58
     59This release builds on the structural improvements made in 0.15 to enhance the code and add new features.
     60
     61Here are some of the most prominent changes:

     98=== 0.15.0 Release ===
     99
     100It took a lot longer than planned, but it is finally here and we think it was worth the wait.
     101The fact that the 0.14 LTS branch will continue to be supported for a while allowed us to drop compatibility with older platforms, remove workarounds and the ugly code that goes with it. This new release also received more regression testing than any release before it.
     102
     103Here are the most noteworthy features and changes:
     104* [/wiki/Clients/HTML5 HTML5 Client] has been thoroughly re-worted by Josh Higgins, you can test drive it here: [http://xpra.org/html5/connect.html].
     105* [/wiki/Printing Printer forwarding]: you should be able to print on your local printer from a remote session
     106* [/wiki/Encodings/nvenc NVENC]:
     107 * support for SDK versions 4 and 5 (newer cards and drivers)
     108 * Lossless mode
     109 * YUV444 mode (no colour subsampling)
     110* [/wiki/Encodings/vpx libvpx] 1.4 and VP9 support (#832): with the proper configuration, VP9 is now competitive with x264 and allows us to provide a fast and free-software compatible encoding!
     111* Sound is now handled out of process, which makes it more reliable (#669 fixes some crashes with the clipboard) and less susceptible to latency jitters in the main process (and we should have audio-video synchronization in the next release: #839), you can also select the sound source (#673, ie: use alsa instead of pulseaudio), and you can start with sound turned off and start it up later (rather than having it on or off globally), the sound bandwidth is shown on the session information bandwidth graphs
     112* Remote client logging (#786): forwards the client's log messages to the server (enabled by default with OSX and MS Windows clients, but disabled in the default server configuration)
     113* Window management (#775 and many other tickets): still working towards a more standards compliant window manager implementation
     114* the OSX build is now automated using modulesets (#533) based on [http://www.gtk.org/download/macos.php gtk-osx]'s + [https://wiki.gnome.org/Projects/Jhbuild jhbuild], so it is now much easier to get going and will allow us to move to 64-bit more easily (#840) - many thanks to Stephen Gauthier
     115* Python 3 support (#640 - ongoing): you can now build the xpra client for either Python 2.x or Python 3, the RPM packaging has been updated accordingly. (this remains a work in progress, especially on MS Windows and OSX)
     116* Older platforms have been dropped (you should continue to use the 0.14.x LTS branch for those):
     117 * centos 5.x because of its older Python 2.4
     118 * Ubuntu Precise and Debian Wheezy because we no longer support their version of libav (though it is still possible to build and run xpra without it)
     119* Picture encoding improvements, ie: faster image re-striding, multi-delta regions (#756 minimizes the bandwidth used by browsers unnecessarily repainting the screen)
     120* You can now start new commands in an existing session from the tray (#638 - this is disabled by default), or via the "xpra control" interface
     121* The automatic window downscaling can now be controlled from the command line (#692)
     122* We now include the manual in HTML format in the OSX image and MS Windows installers
     123* Better window grouping on MS Windows when forwarding multiple applications (#799 requires Windows 7 and later)
     124* More unit tests and regression testing (#660, #177)
     125* Improved logging, bug reports, error messages, etc..
     126
     127There are many other changes under the hood too, too many to list here.

     135== 2014-08-17 ==
     136=== 0.14.0 Release ===
     137
     138This 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.
     139
     140In 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.
     141Should there be another security issue with lz4 / lzo (see [http://blog.securitymouse.com/2014/06/raising-lazarus-20-year-old-bug-that.html The 20 Year Old Bug that Went to Mars]) or even zlib (ie: [http://www.cvedetails.com/cve/CVE-2005-2096/ CVE-2005-2096]), then the application can be secured using configuration changes only, without having to wait for a security update.
     142This is most important for platforms which do not have a real native package manager (MS Windows and Mac OSX).
     143
     144We 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 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). The repository contains everything needed for building everything from source.
     145Users 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)
     146
     147There is also a new integrated [/wiki/ReportingBugs#BugReportTool bug reporting tool], and many performance optimizations. The new lzo compression module allows Debian / Ubuntu users to finally benefit from a more modern compression algorithm, at least until lz4 becomes available for all releases. OpenGL accelerated client rendering is now supported on centos 6.5.
     148
     149One major new feature is the automatic display selection, which means that you no longer need to choose a free X11 display (thanks to Benoit Gschwind).
     150
     151
     152This will be the last release to support python 2.5 and older, libav, old versions of GTK, etc..
     153
     154* RPM packaging changes: #613, #606
     155* support for lzo compression (r6986)
     156* support for choosing the compressors enabled (lz4, lzo, zlib) - #614
     157* support for choosing the packet encoders enabled (bencode, rencode, yaml) - #614, r6934
     158* support for choosing the video decoders enabled - #614
     159* built in bug report tool, capable of collecting debug information - #627
     160* automatic display selection using Xorg "{{{-displayfd}}}" - #172
     161* better video region support, increased quality for non-video regions - #410

     168* better avahi mDNS error reporting - r7109 + r7110
     169* better clipboard compression support - #621
     170* better packet level network tuning and cleanups - r7040, r7021, r7019, r6963, r6953, r6951, r6950, r6949, #581, #614
     171* support for input methods - #634
     172* xpra info cleanups and improvements (show children, more versions, etc) - r6960, r6959
     173* integrated keyboard layout detection on *nix - r6931
     174* upgrade and shadow now ignore start child - r6851
     175* improved automatic encoding selection, also faster - #410, #419, #620

     254(Taken from the [http://lists.devloop.org.uk/pipermail/shifter-users/2014-January/000792.html release announcement]:)
     255[[BR]]
     256This new major release brings a number of new exciting and exclusive
     257features:
     258* [/wiki/Encodings/nvenc NVENC] support for hardware accelerated h264 encoding on Nvidia cards, this can compress video frames [http://xpra.org/stats/NVENC/ much faster] than your CPU ever will, which means that screen updates can get to your client very quickly. xpra is the first open source software to support NVENC.
     259* Support for [/wiki/CSC/OpenCL OpenCL] and [/wiki/CSC/NVCUDA CUDA] acceleration of [/wiki/CSC colourspace conversion]
     260* [/wiki/ProxyServer Proxy mode] for serving multiple sessions through a single TCP port:
     261* Support for sharing a TCP port with a server: "{{{--tcp-proxy=HOST:PORT}}}"
     262Non-xpra traffic will be forwarded to the target of your choice, which
     263can be very useful for serving both HTTP and xpra from the same port. See #474
     264* New and extensible [/wiki/Authentication authentication mechanisms]
     265* mDNS support: your xpra sessions will be advertised unless you
     266specify the switch "{{{--no-mdns}}}"
     267* support for transparency with OpenGL windows and with 8-bit PNG modes
     268* "remote shadow start" so you can clone an existing remote X11
     269display to your desktop in one command: "{{{xpra shadow ssh:HOST:0}}}"
     270* Support for faster [/wiki/PacketEncoding#lz4vszlib lz4 compression] which can make a [http://xpra.org/stats/lz4/ significant improvement in latency] with RGB encoding, and a [http://xpra.org/stats/bencode/ faster Cython bencoder]
     271* {{{ffmpeg}}} and {{{libav}}} are no longer required for {{{vpx}}} and {{{x264}}} support, as we ship a (slower) fallback module.
     272* improved system tray support and native integration
     273* stricter and safer value parsing
     274* more detailed status information via UI and "xpra info"
     275* experimental HTML5 client (#473)
     276* non xpra clients are rejected with a more friendly response
     277* {{{libvpx 1.3}}} and {{{ffmpeg 2.1.3}}} for OSX, MS Windows and static builds
     278
     279And the usual cleanups and refactorings to make the code easier to
     280work on. The wiki has been updated and has quite a few new pages too.
     281
     282The development for version 0.12 is about to start, and we already
     283have [/milestone/0.12 quite a few tickets queued up].
     284But if you have requests or killer features you would like to see
     285added, do let us know.
