A stable release of noVNC is now available. Lots of changes have been made since the last release, but the highlights are:

Application:

• Added French and Portuguese (Brazil) translations.
• The novnc_proxy command (earlier launch.sh) is now able to interface better towards Websockify and now has it's own man page.

Library:

• RTCDataChannel is now supported as a communication channel, an alternative to WebSockets.
• Resizes of the viewport are handled in a more modern way. This allows our library to not only react on browser window changes, but to size changes of the screen element as well.
• Fixed a bug with the Alt key on Firefox.
• Fixed a disconnect that happened when using some VNC servers. The error displayed in this case was "Error decoding rect: TypeError".
• Plain authentication passwords now support longer passwords, which can be useful if you're using a password manager.
• Support for Internet Explorer has been dropped. This made it possible to use more modern features and clean up a large number of workarounds.

_This is a vulnerability fix release._

Fixes a XSS issue in which the remote VNC server could inject arbitrary HTML into the noVNC web page via the messages propagated to the status field, such as the VNC server name.

This affects users of vnc_auto.html and vnc.html, as well as any users of include/ui.js.

Thanks to David Wyde of Cisco for reporting the issue.

Major Changes Since 0.5.1

_Warning: this release removes support for legacy browsers, namely IE9 and below. IE10 may receive "best-effort" support. IE 11+, Edge, Firefox 31+, and Chrome 44+ continue to be supported_

_Warning: this release includes a number of potentially breaking changes to internal libraries_

Thanks to all the contributors who filed bugs, added features, and fixed bugs during this release 🎉
