Hello everyone!
I'm glad to inform you that we have released TightVNC 2.8.53. Download
new version here:

What's New:
* 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.
