What's new in this version:

Fixed:
- Security fix: support for OpenSSH's new kex-strict protocol modification, addressing a vulnerability in some @openssh.com cipher and MAC modes, in particular ChaCha20+Poly1305
- Bug fix: the MSI-installed version of putty.exe can now find its help file again
- Bug fix: a server sending non-displaying terminal escape sequences such as ESC[0m now no longer resets the scrollback to the bottom of the window
