9 September 2016
  • FIXED: VNC connections made via a proxy server are now more likely to succeed. If connectivity problems persist (for example, because the proxy server only permits HTTP/S traffic), try turning off Connect via Proxy from the VNC Viewer Settings menu.
  • FIXED: The formatting of text pasted to the same remote computer it was copied from is now preserved.


3 September 2016
