What's new in this version:

- 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
