Software Update: PuTTY 0.76

A new release of PuTTY has become available. PuTTY is one of the most popular telnet and ssh clients, which makes it possible to remotely manage a computer over a secure connection. Originally, the program was only available for Windows, but today there are also clients for the various Unix platforms. The changelog for version 0.76 can be found below.


  • 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.
  • Crash on Windows when using MIT Kerberos together with ‘Restart Session’.
  • Windows PuTTY leaked named pipes after contacting Pageant.
  • Windows PuTTY didn’t update the window while you held down the scrollbar arrow buttons long enough to ‘key-repeat’.
  • User color-palette reconfiguration via ‘Change Settings’ were delayed-action.
  • Server color-palette reconfigurations were sometimes lost.
  • A tight loop could occur on reading a truncated private key file.
  • The Windows Pageant GUI key list didn’t display key lengths.
