Changelog:
These features are new in 0.76 (released 2021-07-17):

    New option to abandon an SSH connection if the server allows you to \ 
authenticate in a trivial manner.
    Bug fix: Windows PuTTY crashed when the 'Use system colours' option was used.

Session'.
    Bug fix: Windows PuTTY leaked named pipes after contacting Pageant.
    Bug fix: Windows PuTTY didn't update the window while you held down the \ 
scrollbar arrow buttons long enough to 'key-repeat'.

delayed-action.
    Bug fix: server colour-palette reconfigurations were sometimes lost.
    Bug fix: a tight loop could occur on reading a truncated private key file.

These features were new in 0.75 (released 2021-05-08):

    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.
