2023-08-26 PuTTY 0.79 released
Today's release of PuTTY 0.79 is mostly a bugfix release, with only minor new features for SSH and terminal mouse handling.
The most important bug fix is the way we've restored the Windows "install scope" into 0.77 and earlier, restoring the security workarounds we had to put into 0.78. This means that the 0.79 Windows installer will not automatically uninstall 0.78, so we recommend that you manually uninstall 0.78 first (if you have it installed). As before, if you end up with both versions installed, uninstalling them and running a new installer will make everything work.
