PuTTY 0.50 is released

[Simon Tatham]

PuTTY version 0.50 is released.

All the pre-built binaries, and the source code, are now available
from the PuTTY website at

    http://www.chiark.greenend.org.uk/~sgtatham/putty/

The list of new features is too long to quote verbatim, but some of
the highlights are:

  - RSA public key authentication is now supported. The key files
    you can use are the same format as the ones generated by Unix
    ssh-keygen programs (for SSH 1). PuTTY doesn't yet have its own
    key generation utility, but it will.

  - The SSH 2 protocol is now supported. Note that only password
    authentication is supported when using SSH 2, because the SSH 2
    public key algorithm (DSA) has a serious security problem. Now
    that RSA is free of patent issues, I expect the SSH 2 protocol
    to be updated to allow RSA public keys. When that happens, PuTTY
    will start to support public key authentication in SSH 2.

  - We now provide Pageant, which is an SSH authentication agent.
    Like the usual Unix ssh-agent, you can run Pageant and get it to
    hold your RSA keys, so you only need to type each passphrase
    once at the very start of your login session. PuTTY can forward
    agent connections to the remote server, so your local key can
    authenticate further SSH connections from that server to others.

  - We now provide Plink, which is a command-line SSH client. Plink
    supports all of PuTTY's normal authentication options, but gets
    its input and output straight from stdin and stdout. This makes
    it usable as a transport layer for CVS on Windows NT. Note that
    Plink is not expected to work on Windows 95/98/Millennium.

  - Many bug fixes and internal cleanups. In particular, resizing
    the PuTTY window doesn't create so much chaos at the server end,
    and the long-standing bug which prevented underlines appearing
    in some fonts is now fixed.

Enjoy using PuTTY!

Cheers,
Simon
