VNC stands for Virtual Network Computing. It is remote control software which allows you to view and interact with one computer (the "server") using a simple program (the "viewer") on another computer anywhere on the Internet.
The two computers don't even have to be the same type, so for example you can use VNC to view an office Linux machine on your Windows PC at home. VNC is freely and publicly available and is in widespread active use by millions throughout industry, academia and privately.
This version includes both the VNC server and viewer.
# All platforms
* NEW: VNC is available in French, German, and Spanish. The appropriate language for the desktop of each user is automatically selected. This can be changed (if required) using the Locale VNC parameter.
* VNC parameters that parse environment variables (such as LogDir) now resolve the syntax $$ to a literal $, for example to accommodate such a character in a folder name.
* FIXED: The VNC Viewer chat interface no longer prevents a user account password being entered at the Login window or lock screen.
* Chat and file transfer are no longer separate applications but rather merged into the vncserverui.exe program. To configure chat and file transfer using Group Policy, examine the VNC Server > mode > User Interface policy folder.
* FIXED: VNC applications can now be run from user accounts with a $ character in the account name.
* VNC Server in Service Mode (vncserver-x11-serviced) and the VNC Server in Virtual Mode daemon (vncserver-virtuald) can now be started using systemctl on Linux distributions that support systemd, such as the latest Fedora.
* VNC Server now supports PAM session modules, and session actions in pam_umask.so, pam_limits.so, pam_env.so, and pam_unix.so are automatically referenced in /etc/pam.d/vncserver (or equivalent file).
* Chat is no longer a separate application but rather merged into the vncserverui program. To configure chat using policy, edit the vncserverui-<mode> policy template file.
* FIXED: VNC hosted on a network share no longer relies on the cacerts.pem file.
# Mac OS X
* NEW: VNC Server in Service Mode can lock the computer or start the screensaver when the last VNC Viewer user disconnects (not available under OS X 10.4).
* The VNC Chat.app no longer reads from the /Library/Preferences/com.realvnc.vncchat.plist file. To configure chat using policy, edit the vncserverui-<mode> policy template file.
* FIXED: VNC Viewer no longer prevents media keys such as volume or brightness from affecting the client computer.
