TightVNC 2.8.53

TightVNC 2.8.53

• Server and Viewer for Windows: Added support for Unicode clipboard transfers (UTF-8). The latest public version of the standard RFB protocol (3.8) does not support Unicode text, so we implemented this via a new TightVNC protocol extension. This feature will work when supported at both ends of the connection.

• Server for Windows: Added support for Echo messages to let viewer software check responsiveness of a server. This may be used for detecting network failures faster when there is no other traffic between Server and Viewer, and will work only with viewers that support and use this new protocol extension. Echo messages will be supported in our latest SDKs but normal TightVNC Viewer does not use them yet.

• Server for Windows: Protection against brute-force attacks has been improved. Previously, the server allowed no more than 10 authentication failures per 30 seconds from the same IP address. Now the algorithm is more complicated: 1-second timeouts after 2 attempts, 1-minute timeouts after 8 attempts, and 1-hour timeouts after 14 attempts. In other words, it would allow no more than 38 authentication attempts within 24 hours per one IP address.

• Server for Windows: Now it's possible to connect to an active RDP session.

• Server for Windows: Performance has been improved in modern Windows systems (starting with Windows 8). Dragging windows over the desktop should render many times faster, due to the added support of CopyRect encoding with Direct3D and Desktop Duplication APIs.

• Server for Windows: Performance of file transfers has been improved. In particular, listing contents of large folders should become much faster.

• Server for Windows: Fixed a crash in server running in application mode that could happen when Windows shows UAC (User Account Control) pop-up prompts. This problem is specific to reverse server-to-client connections (sf bug #1507).

• Server for Windows: Fixed clipboard transfers. In certain cases, the server did not send clipboard contents to viewers since it wrongly decided there were no clipboard updates for those particular viewers (sf bug #1403).

• Server for Windows: Fixed crash for large displays, with total resolution over 134 millions of pixels, e.g. 16384 х 8192 and more.

• Server for Windows: Potentially fixed incorrect handling of mouse cursors on certain Matrox video cards.

• Server for Windows: Fixed a memory leak (rather a potential one which would not show up during normal operation).

• Installer for Windows: New "ServiceOnly" configuration option has been added, to prevent TightVNC Server from starting in application mode.

• Viewer for Windows: Fixed AltGr handling for Korean keyboard layout.

TightVNC 2.8.27

• Server for Windows: Fixed server crash on changing window size when sharing one particular window with -sharewindow option (sf bug #1475).

• Server for Windows: Fixed problems with generating incorrect symbols with certain national keyboard layouts, e.g. when pressing "3" in Turkish layout and "6" in Portugese Brazilian ABNT2 layout (sf bugs #1482, #1458).

• Server for Windows: Fixed problem with sending black screen when a viewer requests 16-bit or 8-bit colors with big-endian byte order (sf bug #1473).

• Server for Windows: Fixed an issue with mouse cursor jumping to the top left corner of the screen on requesting full screen update.

• Viewer for Windows: Added support of Romanian diacritical marks.

• Viewer for Windows: Fixed a problem of adding extra null character when transferring text data from clipboard (sf bug #1485).

• Viewer for Windows: Fixed incorrect handling of the -mousecursor command-line option (sf bug #1457).

TightVNC 2.8.23

• Server for Windows: Implemented an adaptive algorithm for improving image quality by re-transmitting static screen areas using lossless compression.

• Server for Windows: Added option to disable screen reading through Direct3D API.

• Server for Windows: Fixed lockup after execution of the command -controlservice –sharewindow.

• Server for Windows: Fixed slowdown while copying screen data through Direct3D API in multi-monitor configurations.

• Server for Windows: Fixed slowdown while searching video windows by a class name.

• Server for Windows: Fixed a descriptor leak (low severity).

• Viewer for Windows: Fixed incorrect character transmission in Swedish keyboard layout.

• Viewer for Windows: Added new -logpath command line option.

TightVNC 2.8.59

December 17, 2020

• Server for Windows: Fixed remote desktop updating problems with -sharedisplay and -sharerect options. If the shared area was changed but its size remained the same, update did not happen.

TightVNC 2.8.81​

TightVNC 2.8.81​

• Server for Windows: Support for the third-party ExtendedDesktopSize pseudo-encoding has been removed due to incompatibility issues, complexity, and error-proneness. It has been replaced with a similar TightVNC-specific protocol extension, the new DesktopConfiguration pseudo-encoding, which allows users to choose a specific monitor in the viewer when a remote host has multiple monitors connected. Multi-monitor handling will be implemented in next versions of

TightVNC 2.8.78​

• Server for Windows: Added handling of the SetDesktopSize command, as lack of its support caused TigerVNC viewer to crash.

• Server for Windows: Fixed slow performance of the Direct3D screen grabber.

• Server and Viewer for Windows: Updated the zlib library to the latest version 1.2.13.

TightVNC 2.8.75​

• Server and Viewer for Windows: Updated zlib and libjpeg libraries to their latest versions. Note that older versions of zlib may have security flaws, so this may be an important reason to upgrade TightVNC.

• Server for Windows: Added server-side support for special protocol extension allowing to display individual monitors in multi-monitor systems. Multi-monitor handling will be implemented in next versions of
