Changes in version 3.3.3

Xvnc

    New options -alwaysshared, -nevershared, -dontdisconnect and -localhost.
    Fixed problem with 16-bit desktops on Solaris and other platforms.
    Default dpi now 75.
    Don't die on non-existent font directory at startup (common RedHat 6 problem).
    Copes with up to 5 pointer buttons.
    Fixed zero-area copy bug.
    Fixed occasional bug when multiple clients and one disconnects.

vncserver

    Work around bug in perl 5.005_02 which caused bad display names such as "snoopy:".

vncpasswd

    Fixed minor bugs.

vncviewer

    Completely new viewer based on Xt. Development has ceased on the old Xlib-based viewer.

Changes in version 3.3.2 R3

Xvnc

    Fixed an important memory leak.

vncserver

    The vncserver script should cope better with different Perl versions.
    X cookies generated more securely.

vncviewer

    Uses shared memory on Linux.
    More secure clearing of password.

Changes in version 3.3.2 R2

Xvnc

    Cutting text inside Xvnc works to a remote viewer again.

    Resource leak fixed which limited total number of times Xvnc could be connected to.

vncserver

    Warns of likely failure when starting a 16 bpp desktop on Solaris.

    No longer tries to find out the geometry, depth and pixel format of the current X display being used. This feature can be enabled if desired by uncommenting a line in the script.

Changes in version 3.3.2

The changes in 3.3.2 will have little effect on the normal user.  There should be a slight increase in speed in certain circumstances, but the majority of changes are 'under the hood'.  The X server is now based on XFree86 3.3.2.  This should make it easier to build on more platforms, and means that it is now based on X11R6.3 rather than X11R6. 

X vncviewer

  • -viewonly, -geometry, -wmdecoration options
  • Options for debugging servers: change -delay to -rawdelay, plus

    • -copyrectdelay, -region
  • Options allowed before or after host:dpynum argument
  • Handle changes to local X keyboard mapping
  • Rudimentary single bit-per-pixel support (thanks to Chris Hooper)

Xvnc server

  • Based on XFree86 3.3.2 distribution
  • Faster pixel-format translation routines
  • Improved HTTP server. Now performs substitution on any files ending in .vnc, so that default options to the VNC applet can be configured on the server side.
  • -economictranslate option to use less memory-hungry translation
  • Supports viewers requesting only a subregion of the screen.
  • Better log file messages with timestamps.
