- Support for OpenSSH certificates, for both user authentication
keys and host keys.
- New SSH proxy modes, for running a custom shell command or
subsystem on the proxy server instead of forwarding a port through it.
- New plugin system to allow a helper program to provide responses
in
keyboard-interactive authentication, intended to
automate one-time password systems.
- Support for NTRU Prime post-quantum key exchange,
- Support for AES-GCM (in the OpenSSH style rather than RFC 5647).
- Support for more forms of Diffie-Hellman key exchange: new larger
integer groups (such as group16 and group18), and support for using
those and ECDH with GSSAPI.
- Bug fix: the 32-bit Windows build now runs on Windows XP again.
- Bug fix: server-controlled window title setting now works again
even if the character set is ISO 8859 (or a few other affected
single-byte character sets).
- Bug fix: certain forms of OSC escape sequences (sent by some
real servers) could cause PuTTY to crash.
- Bug fix: the
-pwfile/-pw options no
longer affect local key passphrase prompts, and no longer suppress
Plink's anti-spoofing measures.
- Note: installing the 0.78 or later Windows installer will
not automatically uninstall 0.77 or earlier, due to a
change we've made to work around a bug. We recommend uninstalling
the old version first, if possible. If both end up installed,
uninstalling both and then re-installing the new version will fix
things up.
