PuTTY v0.78 Released-29.10.2022

New update:29.10.2022
-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.
