These features are new in beta 0.58 (released 2005-04-05):
    * Wildcards (mput/mget) and recursive file transfer in PSFTP.
    * You can now save your session details from the Change Settings dialog box, after
      you've started your session.
    * Various improvements to Unicode support, including:
          o support for right-to-left and bidirectional text (Arabic, Hebrew etc).
            Thanks to arabeyes.org for design and most of the implementation.
          o support for Arabic text shaping, again thanks to arabeyes.org.
          o support for Unicode combining characters.
    * Support for the xterm 256-colour control sequences.
    * Port forwardings can now be reconfigured in mid-session.
    * Support for IPv6. Thanks to unfix.org for having patiently maintained the patch
      for this until we were finally ready to integrate it.
    * More configurability and flexibility in SSH-2 key exchange. In particular, PuTTY
      can now initiate repeat key exchange during the session, which means that if your
      server doesn't initiate it (OpenSSH is known not to bother) you can still have the
      cryptographic benefits.
    * Bug fix: display artefacts caused by characters overflowing their character cell
      should now all be gone. (This would probably have bothered Windows ClearType users
      more than anyone else.)
    * Bug fix: keepalives are now supported everywhere. (Previously they were
      supported by Windows GUI PuTTY, but were missing in Plink, PSFTP and the Unix port.)
    * Miscellaneous improvements for CJK/IME users; many thanks to Hung-Te Lin for
      assistance.

These features are new in beta 0.57 (released 2005-02-20):
  * Security fixes: two vulnerabilities discovered by iDEFENSE, potentially allowing
    arbitrary code execution on an SFTP client by a malicious SFTP server (but only
    after host key verification), have been fixed. See vuln-sftp-readdir,
    vuln-sftp-string.
  * Fixed small bug with X forwarding to local displays.
  * Fixed crashing bug with remote port forwarding.
  * Fixed handling of SSH2 debug messages (embarrassingly, a bug introduced when
    fixing the previous vulnerability - it was more secure but didn't work any more!).

These features are new in beta 0.56 (released 2004-10-26):

  * Security fix: a vulnerability discovered by iDEFENSE (advisory number 10-27-04),
    potentially allowing arbitrary code execution on the client by a malicious SSH2
    server before host key verification, has been fixed.
  * Ability to restart a session within an inactive window, via a new menu option.
  * Minimal support for not running a shell or command at all in SSH protocol 2
    (equivalent to OpenSSH's "-N" option). PuTTY/Plink still provide a normal window
    for interaction, and have to be explicitly killed.
  * Transparent support for CHAP cryptographic authentication in the SOCKS 5 proxy
    protocol. (Not in PuTTYtel.)
  * More diagnostics in the Event Log, particularly of SSH port forwarding.
  * Ability to request setting of environment variables in SSH (protocol 2 only).
    (However, we don't know of any servers that support this.)
  * Ability to send POSIX signals in SSH (protocol 2 only) via the "Special Commands"
    menu. (Again, we don't know of any servers supporting this.)
  * Bug fix: The PuTTY tools now more consistently support usernames containing
    "@" signs.
  * Support for the Polish character set "Mazovia".
  * When logging is enabled, the log file is flushed more frequently, so that its
    contents can be viewed before it is closed.
  * More flexibility in SSH packet logging: known passwords and session data can be
    omitted from the log file. Passwords are omitted by default. (This option isn'tr
    perfect for removing sensitive details; you should still review log files before
    letting them out of your sight.)
  * Unix-specific changes:
    * Ability to set environment variables in pterm.
    * PuTTY and pterm attempt to use a UTF-8 line character set by default
      if this is indicated by the locale; however, this can be overridden.

These features are new in beta 0.55 (released 2004-08-03):

  * Security fix: a vulnerability discovered by Core Security Technologies
    (advisory number CORE-2004-0705), potentially allowing arbitrary code
    execution on the client by a malicious server before host key verification,
    has been fixed.
  * Bug fix: General robustness of the SSH1 implementation has been improved,
    which may have fixed further potential security problems although we are
    not aware of any specific ones.
  * Bug fix: Random noise generation was hanging some computers and interfering
    with other processes' precision timing, and should now not do so.
  * Bug fix: dead key support should work better.
  * Bug fix: a terminal speed is now sent to the SSH server.
  * Bug fix: removed a spurious diagnostic message in Plink.
  * Bug fix: the `-load' option in PSCP and PSFTP should work better.
  * Bug fix: X forwarding on the Unix port can now talk to Unix sockets as well
    as TCP sockets.
  * Bug fix: various crashes and assertion failures fixed..

These features were new in beta 0.54 (released 2004-02-12):

  * Port to Unix!
  * Dynamic SSH port forwarding.
  * Ability to leave DNS lookups to the proxy, when using a proxy.
  * Sped up PSFTP.
  * Fixed various bugs, notably one which was impeding port-forwarding of SMB.
  * Some default settings changes: SSH and SSH2 are now default, BCE is off.
