Bug fix: 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.Bug fix: in a session using the ‘Raw’ protocol, pressing ^D twice in the terminal window could cause an assertion failure.Backwards compatibility fix: certificate-based user authentication now works with OpenSSH 7.7 and earlier.Terminal mouse tracking: support for horizontal scroll events (eg generated by trackpads).Terminal mouse tracking: support for mouse movements which are not drags.If both end up installed, uninstalling both and then re-installing the new version will fix things up. In that situation we recommend uninstalling 0.78 first. Note: this means that installing the 0.79 or later Windows installer will not automatically uninstall 0.78, if 0.78 was installed using its default ‘per user’ scope. Windows installer scope is back to the normal ‘per machine’ setting, reverting 0.78’s security workaround.The changelog for this release can be found below. Due to an issue, Windows users are recommended to uninstall the old version first.

Originally the program was only available for Windows, but nowadays there are also clients for the various Unix platforms.
