This page contains download links for PuTTY release 0.68.

Past releases of PuTTY are versions we thought were reasonably likely to work well, at the time they were released. However, later releases will almost always have fixed bugs and/or added new features. If you have a problem with this release, please try the latest release, to see if the problem has already been fixed.


This release has known security vulnerabilities. Consider using a later release instead, such as the latest version, 0.81.
