PuTTY Portable full changelog

PuTTY Portable 0.81 released Apr 15, 2024 (New Release)
Security fix for CVE-2024-31497: NIST P521 / ecdsa-sha2-nistp521 signatures are no longer generated with biased values of k. The previous bias compromises private keys.
PuTTY Portable 0.79 released Aug 28, 2023 (New Release)
PuTTY Portable 0.78 released Oct 30, 2022 (New Release)
PuTTY Portable 0.77 released May 30, 2022 (New Release)
PuTTY Portable 0.76 released Jul 19, 2021 (New Release)
PuTTY Portable 0.75 released May 9, 2021 (New Release)
Security fix: on Windows, a server could DoS the whole Windows GUI by telling the PuTTY window to change its title repeatedly at high speed.
Pageant now supports loading a key still encrypted, and decrypting it later by prompting for the passphrase on first use.
Upgraded default SSH key fingerprint format to OpenSSH-style SHA-256.
Upgraded private key file format to PPK3, with improved passphrase hashing and no use of SHA-1.
Terminal now supports ESC [ 9 m for strikethrough text.
New protocols: bare ssh-connection layer for use over already-secure IPC channels, and SUPDUP for talking to very old systems such as PDP-10s.
PuTTYgen now supports alternative provable-prime generation algorithm for RSA and DSA.
The Unix tools can now connect directly to a Unix-domain socket.
PuTTY Portable 0.74 released Jun 28, 2020 (New Release)
PuTTY Portable 0.73 released Oct 1, 2019 (New Release)
PuTTY Portable 0.71 released Mar 20, 2019 (New Release)
PuTTY 0.71 includes a large number of security fixes, many of which were found by the recent EU-funded HackerOne bug bounty. There are also other security enhancements (side-channel resistance), and a few new features. It's also the first release to be built for Windows on Arm.
PuTTY Portable 0.70 released Sep 28, 2017 (New Release)
Security fix: the Windows PuTTY binaries should no longer be vulnerable to hijacking by specially named DLLs in the same directory, even a name we missed when we thought we'd fixed this in 0.69. See vuln-indirect-dll-hijack-3.
Windows PuTTY should be able to print again, after our DLL hijacking defences broke that functionality.
Windows PuTTY should be able to accept keyboard input outside the current code page, after our DLL hijacking defences broke that too.
