Download PuTTY: latest development snapshot

The development snapshots are built every day, automatically, from the current development code – in whatever state it's currently in. So you may be able to find new features or bug fixes in these snapshot builds, well before the same changes make it into the latest release. On the other hand, these snapshots might also be unstable, if a lot of new development has happened recently and introduced new bugs.

In particular, they may contain security holes. If we find one that's not also in a release, we're likely to just fix it in the next day's snapshot. If it's a particularly bad one we might make a note on the wishlist page.

You probably want one of these. They include versions of all the PuTTY utilities (except the new and slightly experimental Windows pterm).
