4.1 beta

2008-03-20

SSH core upgraded to PuTTY 0.60. It brings following changes:
- Support for “local proxying”, where a network connection is replaced by a local command.
- Various cryptographic improvements in SSH-2, including SDCTR cipher modes and a workaround for a weakness in CBC cipher modes. Support for Diffie-Hellman group exchange with SHA-256 was not included due to performance problems.
- Support for the Arcfour cipher in SSH-2.
- When Pageant is running and an SSH key is specified in the configuration, WinSCP will now only try Pageant authentication with that key. This gets round a problem where some servers would only allow a limited number of keys to be offered before disconnecting.
- Support for SSH-2 password expiry mechanisms, and various other improvements and bugfixes in authentication.
- A change to the SSH-2 password camouflage mechanism in 0.58 upset some Cisco servers, so we have reverted to the old method.
- If authentication challenge includes multiple prompts, all are displayed in one form.
- Random seed file is being stored to application data folder when possible.
- Bug fix: SSH-1 connections tended to crash, particularly when using port forwarding.
- Bug fix: SSH Tectia Server would reject SSH-2 tunnels from WinSCP due to a malformed request.
- Bug fix: SSH-2 login banner messages were being dropped silently under some circumstances.
- Bug fix: IPv6 should now work on Windows Vista.
Stored sessions can be organized into folders. 34
Switched to Quest PuTTY implementation of Kerberos/GSSAPI. It brings following changes:
- Preference of GSS key exchange algorithms can be configured on Key exchange tab of login dialog.
- Session option Allow Kerberos 5 ticket forwarding in GSSAPI/SSPI obsoleted (was probably useless anyway).
- Session option Server realm renamed to Service principal name.
Added several switches to scripting commands to extend their capabilities with functionality available in GUI already:
- -mirror and -criteria 59 for synchronize;
- -delete for synchronize and keepuptodate (obsoletes option synchdelete);
- -permissions, -nopermissions and -speed 109 for get, put, synchronize and keepuptodate;
- -delete, -preservetime and -nopreservetime for get and put;
- -timeout, -privatekey and -passive 132 for open.
Added switch /hostkey to command-line and open script command to automatically accept host keys with given fingerprint.
Environment variables can be used in scripting commands. The syntax is %NAME%. 76
Command Duplicate can transfer files in between different opened sessions (via local temporary copy). It can also be used to duplicate the file within the session, if the protocol does not allow direct duplication. 127
In file panel, file sorting by date and size is by default descending.
Speed limit can be actually set in KiB/s.
Speed limit can be set for background transfers.
Custom command to execute SFTP server binary may be specified. This allows using su to run SFTP server. 84
Transfer settings were removed from transfer options dialog to simplify it. The settings can be changed by selecting transfer settings preset or by invoking custom transfer settings dialog (the same way as for synchronization).
More than one host key for a host may be accepted.
It is possible to cancel connection attempts of background transfer.
Proxy settings to check for updates can be automatically detected from system and IE settings.
Improved keepalive mechanism of FTP sessions by listing current directory in regular intervals.

Change: Removed One file only editing mode.
During resumable transfers, the destination file is not removed (if present) until the transfer actually finishes.
When opening secondary shell session, startup actions like clearing of aliases, unsetting national variables and looking up user groups are not performed.
For SCP protocol, listing command can be fully specified to overcome specifics of platform (this obsoletes former option Alias LS to display group name). 142
New patterns for custom commands: !/ expands to current remote path, !@ expands to current session hostname. !u expands to username, !p expands to password. 48
Escaping of special characters is reversed on upload. 32
Custom FTP commands can be executed after login. 162
Transfer and session toolbars automatically stretches to right window edge.
Command line panel is toolbar (can be docked elsewhere).
Address and command line drop down boxes follow the toolbar style.
On Explorer interface, path on address toolbar is editable.
KiB is used instead of KB for kilobyte.
Estimated time is shown instead of elapsed time in queue list.

WinSCP starts on the same monitor it was closed the last time. 135
Notification balloon is not displayed after background upload of edited/opened file is finished. 143

Size of directory change cache is limited.
Error messages of background transfer are actually presented as errors.

Improved initial placing of Commander window.
Improved call command description with respect to FTP protocol.
ftp protocol added to command-line syntax help.
Most options on SCP tab of login dialog are disabled, when SCP protocol is not selected, to avoid confusion (although they can actually be used when SCP fallback is administered).
