TightVNC 2.8.11

Server for Windows: Implemented performance improvements that may notably increase update speed and optimize CPU usage.
Viewer for Windows: Fixed a problem that might cause the viewer to continue sending keyboard events even after minimizing a full-screen window.
Viewer for Windows: Fixed an incorrect calculation in keyboard handling, which unlikely caused any problems though.
Source Code for Windows (Server and Viewer): Migrated to Visual Studio 2015 and MSBuild tool set as the primary build environment.

Server for Windows: Fixed minor resource leaks (GuiThread and SocketIPv4 objects did not always closed all their handles properly).
Server for Windows: Built-in Java Viewer updated to its latest version (2.8.3).

Server for Windows: Added support for "IdleTimeout" registry key which specifies how many seconds to wait for mouse or keyboard events. If there was no activity from a client during the specified timeout, the corresponding client will be disconnected. The value 0 (DWORD) stands for no timeout at all (stay connected forever), and that's the default setting. This setting is not configurable from the user interface.
Server for Windows: Improved handling for screen orientation changes.
Server for Windows: Significantly improved screen reading performance on Windows 8 with multiple monitors (sf bug #1324).
Server for Windows: Fixed a problem with the Alt key becoming stuck in the pressed state after Alt-Tab switching in Windows 8 (sf bugs #1341, #1311, #1303, #1302).
Server for Windows: Fixed built-in HTTP server crash on Windows XP and Windows 7 when the request URL includes parameters (sf bug #1344).
Server for Windows: Fixed a rare problem triggered when a server shares one display in multi-monitor configuration, with more than one viewer connected. If a user on the server changed the focus to other display, the viewers could see the active windows from the other display on top of the shared display and everything became messy.
Server for Windows: Fixed server-side clipboard handling. After receiving clipboard contents from a client, the server could return the same clipboard data back to the same client, and clipboard could be damaged on the viewer side (sf bug #1255).
Server and Viewer for Windows: Fixed a bug with truncating data from clipboard, due to an error in calculating text length in Unicode/ANSI conversions (sf bug #1337).
Viewer for Windows: Fixed possible memory access violation caused by incorrect calculation of buffer size in the StringStorage object (sf bug #1356).
Viewer for Windows: Fixed a bug with deleting random characters from the host:port string. The bug was caused by incorrect calculation of the number of Unicode characters (sf bug #1349).
Viewer for Windows: Fixed problems with Shift, Alt and Ctrl keys getting locked in the pressed state on switching from the viewer window to other applications (sf bugs #1360, #1329, #1174).
Viewer for Windows: Fixed a problem which prevented from connecting to a Dispatcher using big ID numbers (ID >= 2147483648).
Viewer for Windows: A typo has been fixed in the warning window shown on entering the full-screen mode (sf bug #1270).
Server and Viewer for Windows: Removed libjpeg-turbo library in favor of the standard libjpeg. The accelerated library did not show major performance improvements in typical situations but introduced questionable requirements on the hardware and the compiler. The codebase goes cross-platform, so we chose to get rid of such dependencies.
Java Viewer: Added new -showConnectionDialog command-line option. Set to "No" if you do not want to show initial connection dialog. Default: "Yes".
Java Viewer: Fixed an issue that resulted in error message "Value too long" (sf bug #1379).
Java Viewer: Increased Java compatibility requirement, now it requires Java 1.7 (previous versions required Java 1.6).

* Improved a File transfer window: file listing in the directory is now case insensitive.
* Added sorting of files by Name, Size or date Modified either in ascending or descending order.

# Server for Windows:
- Fixed a bug with multi-monitor configurations running on Windows 8. The main display can be safely set to any monitor in a row or column.
- On Windows 8, data is no longer corrupted when the screen resolution is not divided by four (native resolution for some laptops).
- No more issues on the Server side when a zero compression level is set in the Viewer settings (Options > Set custom compression level > level: 0).
- Fixed incompatibility with older versions of TightVNC Viewer (1.3.10).

# Viewer for Windows:
- Fixed a keyboard bug: it stopped working after a file transfer window is opened.

* Server for Windows
- Fixed an issue on connection to a server from a built-in remote desktop client on Mac.
- You can safely change screen properties (resolution, etc.) on the server running on Windows.
- No more bad desktop size issues if the server is running on Windows 7 (SP1) or Windows Server 2008 (SP1) while there are no drivers installed. A server can be run on a virtual machine as well.
- Added more verbose logging (when a logging level is set to 9).
- Improved performance when the remote desktop is shown in its original size. Moreover, the image quality is now improved in case pixel-size checkerboard patterns are used.
- Optimized Tight encoding to work faster.
- Increased speed of ZRLE encoding up to 25%.
* Java Viewer
- Fixed a compatibility issue with non-TightVNC servers (Mac remote desktop, UltraVNC) when ZRLE encoding is used.
- Optimized memory usage when Tight or ZRLE encoding is used.

# Server for Windows
- If a server is running on Windows 8, remote desktop screen is updated much faster.
- Now it is possible to show a single application rather than the whole remote desktop. For that, run a server with a -shareapp CLI option and pass a running process ID as its argument.
- Increased security when password protection for a server is used: if Administration > Ask password for each operation is checked, a password is required each time the settings are changed.
- Administration -> Protect control operations with a password flag is: if checked, a password is required each time the settings are changed.
- Added ZRLE and RRE encoding support.
- Fixed issues when Extra Ports are used: now clients can safely establish connection to a server.
- When a client has disconnected, pressed key states are reset on the server side.
- Fixed an issue with drawing of a cursor on the server side when Let remote server deal with cursor option is enabled in the Viewer settings. Transparency issues for a cursor are also fixed.
- Fixed a bug with desktop size after the screen DPI is changed.
- Invalid JPG data now leads to error throwing rather than crashing.
- Fixed a bug with queued and non-sent updates on desktop changes.
- Fixed a missing system libraries error on Windows 2003 (sometimes wtsapi32.dll or psapi.dll could not be found).
# Viewer for Windows
- Now it is possible to change the port the Viewer listens on (in the Listening mode) and reconnect to the server right on the fly.
- Now Viewer can successfully connect to servers that require RFB protocol 4.0 or higher (in fact, RFB 3.8 will be used to establish connection).
- If minimized, a full-screen window is now restored as a full-screen application rather than a windowed one.
- Ctrl + M command is now applicable when in the full-screen mode.
- Now correct resolution is reported in the Connection info window when a remote screen size is not divided by 4.
- Fixed invalid memory allocations that caused Viewer to crash when a Tight or ZRLE decoder is used.
- Fixed a bug with VNC session files if a port is less than 100.

Installer for Windows: New USEMIRRORDRIVER MSI property.
Installer for Windows: Now the installer offers setting/changing passwords at the end of each installation.
Installer for Windows: The passwords were not deleted from the registry if the options "do not use ... authentication" were selected or the corresponding properties were set to -1.
Server for Windows: Fixed a crash of TightVNC Server in a service mode on system reboot. A crash dialog appeared on Windows shutdown when the server had connected clients.
Server for Windows: Fixed the Apply button behavior in the Configuration window. It stayed disabled when "Use mirror driver" setting had been changed.

Viewer for Windows: TightVNC Viewer window now adjusts when changing viewport scale.
Viewer for Windows: Now, the pointer position is sent to a remote server only if it has actually changed.
Viewer for Windows: The screen is now updated not at once but gradually, if the encoding is "Raw" and shared screen area is large.
Viewer for Windows: Now, a list of files can be sorted by name, size and modification time in File Transfer system.
Viewer for Windows: Fixed occasional slow remote screen rendering.
Viewer for Windows: Fixed connection option saving.

* Java Viewer:
- Introducing new full-screen mode, with optional auto-scaling, auto-scrolling and a pop-up toolbar.
* Installer for Windows:
- Added new MSI installer properties, to automate pre-setting passwords in silent mode.
* Server for Windows:
- Fixed a problem with querying local users on incoming connections. TightVNC has a feature to let local user approve or reject incoming connections. If there was no user action within a pre-configured time limit, new connection will be either accepted or rejected automatically. Unfortunately, the timeout setting did not work correctly in previous version and that could result in infinite timeouts. That has been fixed.
- Fixed the Apply button in the Configuration window - it stayed disabled on editing configuration settings.
* Viewer for Windows:
- Fixed authentication handling in RFB protocol version 3.7. This should resolve connectivity problems with Ubuntu systems and Vino servers.
- Fixed hang-up on changing language or keyboard layout. To fix this problem, Windows message handling has been re-designed completely.
- Fixed priority of preferred encodings. Previous version could work inefficiently with servers that do not support Tight encoding, because the viewer could choose uncompressed Raw encoding instead of well-compressed ZRLE.
- Eliminated 34-character limit on hostnames in the New Connection window.
- Using correct line ending characters in cross-platform clipboard transfers.
- Introduced a number of improvements and fixes in the user interface. That includes new commands in the toolbar and in the system menu, and architectural changes such as restoring the option to start new connections from the same Viewer instance.
- Adjusting viewer window size on remote desktop resizing.
- Other minor improvements and fixes.
* Source Code (Server and Viewer for Windows):
- Improved logging architecture. The changes will not be visible to end user, but developers will appreciate new logging system. There should be no more static methods and global log objects, so it will be easier to reuse separate components in third-party applications. Now all components work via a simple logging interface or can work without logging at all.
- Corrected build problems in various combinations of build configurations and platforms, in both Visual Studio 2008 and Visual Studio 2010.

* Installer for Windows:
- Parameter-based silent installation. You can pre-configure TightVNC Server via MSI parameters and perform mass installation via a batch file or Group Policy.
- Both 32-bit (x86) and 64-bit (x64) versions of the installer are available.
* Server for Windows:
- Full support for 64-bit systems. Besides obvious benefits of using native architecture, this allows to attach so called "message hooks" to 64-bit applications. In a simple language, message hooks help at detecting screen activity, so that we can get updates almost immediately instead of polling the complete screen once per second or so.
- Support for mirror video driver (DFMirage). This makes screen reading ultra-fast in all supported versions of Windows, from Windows 2000 to Windows 7. DFMirage driver is a separate product, but it's free for TightVNC users (and it's available commercially if needed).
- Improved performance when sharing a desktop with Windows Aero enabled. With Aero, each screen reading operation is expensive, and we can improve performance by reading more pixels in less operations.
- Improved logging. Most importantly, new version reports all incoming connections to Windows Event Log. Also, logging to text files has been improved - the service writes to the same log file from all its child processes. There's always just one log file, so it's easier to locate an error message or e-mail the log to technical support service.
- New option to configure extra ports mapped to arbitrary screen areas. If a client connects to such an extra port, it will be shown the corresponding part of the screen only.
- New command-line options to share full desktop, primary monitor, selected monitor, a window, or an arbitrary rectangular area.
- Optimized video processing for specific window classes. You can tell TightVNC to treat certain windows as video by providing a list of window class names. Once a matching window is detected, its contents will be sent to clients continuously, with minimum delays.
* Viewer for Windows:
- Completely rewritten version, free of GPL-only source code.
- Native 64-bit version for improved performance in x64 systems.
- Fast screen drawing and optimized decoders.
- New ZRLE decoder for improved compatibility with wide range of VNC-compatible servers.
- Desktop scaling that can be easily controlled via the toolbar.
- New feature to pause screen updates. You can freeze the remote desktop at any moment, e.g. to make a screenshot, examine details or demonstrate the screen to other people.
- Unicode-enabled compilation. Unlike previous versions of TightVNC Viewer, this one fully supports Unicode and has no problems with using multiple national languages in user input, screen labels, file names etc.
- Easily reusable source code. The viewer has been redesigned from the scratch. The primary design goal was to develop a "remote control SDK" and build the viewer on top of it. And we've done just that. So not only we provide new version of the viewer, but we also give software developers an easy way to add remote control functionality to their products (both free and commercial). The resulting SDK has a simple interface which hides all the complexity of the underlying protocols. It's written in C++, has minimum dependencies on Windows systems and will be made truly cross-platform in its future versions.
* Java Viewer:
- Desktop scaling that can be easily controlled via the toolbar.
