O Bug fix: SSH-1 connections tended to crash, particularly when using port forwarding. O Random seed file is being stored to application data folder when possible. O A change to the SSH-2 password camouflage mechanism in 0.58 upset some Cisco servers, so we have reverted to the old method. O Support for SSH-2 password expiry mechanisms, and various other improvements and bugfixes in authentication. This gets round a problem where some servers would only allow a limited number of keys to be offered before disconnecting.

O When Pageant is running and an SSH key is specified in the configuration, WinSCP will now only try Pageant authentication with that key. O Support for the Arcfour cipher in SSH-2. Support for Diffie-Hellman group exchange with SHA-256 was not included due to performance problems. O Various cryptographic improvements in SSH-2, including SDCTR cipher modes and a workaround for a weakness in CBC cipher modes. O Support for “local proxying”, where a network connection is replaced by a local command.
