This can be considered a "technology preview", since there are still a
lot of outstanding issues to be addressed, and a few major features to
be added before the beta. One of the remaining major features to be
implemented is the TigerVNC flow-control extensions, for improving
performance on high-latency networks. This effort has been funded and
will be available for preview in the coming weeks.
Major new changes:
-- Support for X RENDER 0.10, which fixes major cosmetic defects
discovered when attempting to run newer window managers and applications
that aren't smart enough to fall back to earlier X RENDER functionality.
KNOWN ISSUE: With some applications, dragging a window off-screen
and back on can corrupt the contents of the window. This is being
investigated.
-- The ability to disable X RENDER when starting Xvnc (pass -norender to
vncserver.)
-- Fixed xstartup.turbovnc to automatically load the 2D version of the
window manager on recent Ubuntu systems, which fixes various defects
such as missing menus. rm ~/.vnc/xstartup.turbovnc prior to starting
TurboVNC so that it will re-create a new one.
-- NO MORE AUTOTOOLS. The entire TurboVNC build, including the Unix
code and Java code, are now part of the same CMake-based build system,
which operates out of the top-level directory.
-- All-new Java viewer code base, which contains most if not all of the
existing TurboVNC features, as well as:
* Built-in support for VeNCrypt and TLS encryption (which can be
used when connecting to TigerVNC servers. We have no immediate plans to
support TLS in the TurboVNC Server due to the pain of maintaining a
cross-compatible GnuTLS build)
* Built-in SSH tunneling support (currently has to be used from the
command line. Looking for funding to expand this into the GUI and add
SSH key, i.e. password-less login, support)
* Can load libjpeg-turbo via JNI, bringing the performance of the
Java viewer to near native levels (there is further performance
optimization work that needs to be done, and I think I can close that
remaining gap.) Note that if you want to build this feature or take
advantage of it at run time, you need to install the latest pre-release
of libjpeg-turbo from here:
http://www.libjpeg-turbo.org/DeveloperInfo/PreReleases (not necessary
when using the Mac app below.)
* Packaged as a stand-alone app on Mac (fully self-contained, with
the Java code as well as the libjpeg-turbo JNI code included in the
app), so the app can be used as a user-friendly alternative to the X11
TurboVNC Viewer.
* Desktop resize support (also for use with TigerVNC servers at the
moment. Looking for funding to implement this in the TurboVNC server.)
This new Java viewer will be the basis for our upcoming Android
client, so we're looking for any and all feedback on it.
KNOWN ISSUE: Configuration load/save is broken at the moment.
Eventually, the Java viewer will be able to load and save .vnc files
like the Windows viewer.
KNOWN ISSUE: Loading the Java viewer using Xvnc's built-in HTTP
server doesn't work if Xvnc is using a display other than :1. This is
being investigated.
-- All viewers and servers should now be fully IPv6 compliant (which
means that TurboVNC can now be used with Microsoft DirectAccess.) Note
that there are new command-line options in Xvnc and vncviewer to force
them to listen only on an IPv6 address. The default behavior is to
listen on both IPv4 and IPv6 addresses, if the system supports that.
