This update for putty fixes the following issues:

- Update to release 0.83
  * Support for ML-KEM, a NIST-standardised post-quantum key
    exchange mechanism.
  * Bug fix: psftp -b works again.
  * Fixed bug which crashed Pageant if an SSH connection is
    abandoned while waiting for a deferred decryption passphrase.
  * Fix a tight loop bug occurring if PuTTY tried to send an
    empty answerback string.
  * Fixed a bug where some configuration edit boxes' contents
    were accidentally truncated to 127 characters.
  * Bug fix: the small keypad keys did not reliably work in the
    terminal on Unix.

- Update to release 0.82
  * Major refactoring of Unicode handling to allow the use of
    'foreign' Unicode characters outside the system's
    configured default character set.
  * Bracketed paste mode can now be turned off in the Terminal >
    Features panel.
  * The "border width" configuration option is now honoured even
    when the window is maximised.
