I am happy to inform you that TightVNC 2.0 is available for download. This version is
the first stable release in new TightVNC 2.x series. The files can be downloaded here:
New major version delivers completely new TightVNC Server for Windows. It was
redesigned and reimplemented from scratch. It features new component-based architecture
which is perfectly compatible with the latest operating systems, Windows 7 and Windows 2008
Server R2. Older versions of Windows are supported as well – the minimum requirement
is Windows 2000.
TightVNC 2.0 is available for Windows only. It does not include components for
Unix/Linux yet. These components will be worked on in the future. In the mean time, please
use TightVNC 1.3.x under Unix/Linux systems. Also, TightVNC Java Viewer should work on any
Below is a list of major improvements in TightVNC 2.0, as compared to the previous stable
version of TightVNC, 1.3.10:
- Introducing new file transfer subsystem based on new protocol extensions. Multiple
files and directories can be copied at once, directories are processed recursively. Data
compression is used to speed-up copying. Files can be renamed or removed, new directories can
be created. File sizes are not limited by 4 Gb any more.
- Implemented new server architecture which separates service code from the user
interface. This enables service-mode operation under Windows Vista and Windows 7. Also, this
fixes all known problems with multi-user features of modern Windows systems like Fast User
Switching and Terminal Services.
- Screen updates have become reliable. If something went wrong and the picture in the
viewer is garbled, incomplete or outdated, it will be recovered in reasonable time. There
should be no more hidden menus or destructive window movements. If fast update detection
methods fail, full-screen polling will keep updates going.
- Featuring new secure administrative interface. What was called "TightVNC tray
icon" in previous versions is now a separate process which acts as a control interface
to the TightVNC service. Control interface can be optionally protected with a password to
make sure users cannot reconfigure or shut down the service unless they know the password (or
have administrator privileges).
- There should be no more confusion between "default settings" and
"user settings". In TightVNC 2.0, there is only one service-mode configuration and
it is not affected by any per-user settings. The "Configure..." menu item of the
service always shows the effective configuration. From the other side, TightVNC Server can be
started as an application, and in that case each user has his/her own configuration.
- Featuring IP-based access control for incoming connections. Previous versions of
TightVNC did allow similar IP filtering, but now everything is easily configurable. You can
even test the rules on specific IP addresses, prior to applying new rules.
- TightVNC 2.0 distribution has been packaged with new installer. It's smarter
and more efficient. It tries to prevent reboots whenever possible. It invites to set
passwords so that TightVNC Server would be ready to work right at the moment of finishing the
installation. From the other side, it can operate silently (when run with /S option in the
command line). Finally, the complete self-installing TightVNC package (both server and viewer
parts, and the uninstall tool) is only 550 kilobytes in size.
- Keyboard handling has been improved. Older versions of TightVNC had problems with
passing characters that do not fit in the Latin-1 code space. TightVNC 2.0 adds full support
for different national codepages and keyboard layouts.
- This list of changes is not full. TightVNC Server 2.0 for Windows has been
completely rewritten by the TightVNC team. It does not include old TightVNC 1.3 code. So the
right answer to the "What's Changed?" question must be
