Release Notes

Significant changes relative to 0.3.1:

1. Incorporated TightVNC 1.3.8 patches (where applicable)

2. Now using a single RPM to support multiple Linux distributions.

3. Fixed a couple of issues in the fallback logic of the default ~/.vnc/xstartup script. It should now properly run fvwm2 or twm if KDE, CDE, or GNOME are not available.

4. First pass at a Mac build of the TurboVNC Viewer. The Mac version is an X11 Unix app and thus needs to be run inside an xterm. It should otherwise behave and perform identically to the Linux version.

5. Increased the size of the TurboJPEG compression holding buffer to account for rare cases in which compressing very high-frequency image tiles (specifically parts of the 3D Studio MAX Viewperf test) with high quality levels (specifically Q99 or above) would produce JPEG images that are larger than the uncompressed input.

   Linux users will need to upgrade to the TurboJPEG 1.04 RPM to get this fix. For other platforms, the fix is included in the TurboVNC 0.3.2 packages.

6. Added -fg switch to vncserver to make it (optionally) run in the foreground. This allows you to kill the VNC server by pressing CTRL-C in the shell you used to start it. When in foreground mode, you can also kill the VNC server by logging out of the window manager inside the VNC session.

7. The /etc/init.d/tvncserver script, which can be used to launch multiple TurboVNC sessions at boot time, should now work properly on SuSE systems.

8. Added TurboVNC protocol optimizations to the Java viewer and made its configuration options match the other TurboVNC viewers. The Java viewer still uses a slower codec, so it is about 3X slower in a LAN environment than the native viewer. The Java viewer also lacks double buffering support. But with these new optimizations, the native and Java viewers should now perform similarly over a wide-area network.

9. Added a -password option to the Windows TurboVNC Viewer to allow one to pass the VNC password as plain text.

Release Notes

Significant changes relative to 0.3:

1. Automatically start Xvnc with -nolisten local on Solaris hosts. On Solaris, /tmp/.X11-unix is not world writable by default, so it is necessary to either start Xvnc with -nolisten local (which forces Xvnc to listen on a tcp port rather than a local pipe) or to make /tmp/.X11-unix world writable. The former approach seemed like the lesser of two evils.

2. The vncserver startup script now sets VGL_COMPRESS to 0 automatically, so it is no longer necessary to supply a -c 0 argument to vglrun when running inside a TurboVNC session.

3. The JPEG quality slider in the Unix viewer's F8 popup menu will now respond to any mouse button, not just the middle one.

4. The WAN protocol optimizations can now be switched on and off. It has been discovered that these optimizations produce slower performance on a LAN, so it is preferable only to use them on high-latency networks.

   On the Windows viewer, the "Broadband/T1" preset now enables the WAN protocol optimizations in addition to setting quality=30 and subsampling=4:1:1. Similarly, the "High-speed Network" preset disables WAN optimizations in addition to setting quality=95 and subsampling=4:4:4. WAN optimizations can also be configured via an additional check box ("High-Latency Network") in the Options dialog or through two new command line switches: /lan and /wan.

   On the Linux/Unix viewer, the default is no WAN optimizations, quality=95, and subsampling=4:4:4. You can specify an argument of -wan to enable WAN optimizations or -broadband to enable WAN optimizations, quality=30, and subsampling=4:1:1. The F8 popup menu also contains a new button for enabling/disabling WAN optimizations, and the Broadband and LAN presets in this window will enable and disable WAN optimizations (respectively.)
