Opera (64-bit)

What's new in this version:

- Terminal mouse tracking: support for mouse movements which are not drags
- Terminal mouse tracking: support for horizontal scroll events (e.g. generated by trackpads)
- Backwards compatibility fix: certificate-based user authentication now works with OpenSSH 7.7 and earlier

Fixed:
- in a session using the 'Raw' protocol, pressing ^D twice in the terminal window could cause an assertion failure
- terminal output could hang if a resize control sequence was sent by the server (and was not disabled in the Features panel) but PuTTY's window was set to non-resizable in the Window panel
- GTK PuTTY could fail an assertion if a resize control sequence was sent by the server while the window was docked to one half of the screen in KDE
- GTK PuTTY could fail an assertion if you tried to change the font size while the window was maximised
- the 'bell overload' timing settings were misinterpreted by Unix PuTTY and pterm 0.77/0.78; if any settings were saved using these versions, confusion can persist with newer versions
- SSH authentication banners were not reliably printed if a server sent one immediately before closing the connection (e.g. intended as a user-visible explanation for the connection closure)
- the 'close' command in PSFTP always reported failure, so that ending a psftp -b batch script with it would cause PSFTP as a whole to believe it had failed, even if everything worked fine
- certificate handling would do the wrong thing, for RSA keys only, if you specified a detached certificate to go with a PPK file that had a different certificate embedded
- Windows Pageant's option to write out a configuration file fragment for Windows OpenSSH now works even if you have a space in your user name
- in local-line-editing mode, pressing ^U now just clears the line, instead of clearing it and then inserting a literal ^U
- Several bug fixes in edge cases of terminal wrapping, involving double-width characters
