It is possible to change width of session drop down menu on Session toolbar. Just drag the empty space on the right of the drop down menu.
Queue sessions are kept alive if the main session is configured so. As side effect dropped connection is detected immediately (no error is displayed), not only after there is transfer attempt over it. It avoids failing transfer just because of dropped connection.
When secondary shell session is dropped on background, no error is displayed and the main session is no longer closed.
If the edited file is saved while the previous change is still being uploaded, the error is no longer displayed, re-upload is scheduled instead.

Bug fix: Scripting command get with SCP protocol printed downloaded directory twice, the second time with statistics of the last file downloaded.
Bug fix: Fixed several bugs when downloading files for which the server incorrectly reports unreasonable file sizes.
Bug fix: WinSCP refused to start, when using /ini parameter without session name parameter.
Bug fix: The download of files smaller then 4 KiB could not be interrupted.
Bug fix: Attempt to open non-existing local directory (Commander interface only) have not displayed any error message. The first existing parent directory (if any) was opened instead.
Bug fix: When downloading file to editor, Exclude mask and operation mask were not ignored, what prevented editing some files.
Bug fix: When using ls command with --full-time option (SCP protocol) the leading spaces in the filenames were omitted while reading directory.
Bug fix: Time estimated showed incorrect values for resumed file transfers.
Bug fix: When downloading file with SCP protocol, any leading spaces in the filename were lost.
Bug fix: Possible crashes when having more sessions opened in parallel.
Bug fix: When using INI file as configuration storage, the quotes enclosing configuration options (particularly path to PuTTY executable) were lost.
Bug fix: Directory was randomly selected in remote panel when switching sessions.
Bug fix: When upgrading from 3.7 and older, command Open in PuTTY stopped working if path to PuTTY included spaces.
Bug fix: Items in queue display menu may have been sometime disabled.
Bug fix: When uploading, the contents of selected directories was counted twice into “total size”, making progress indicator inaccurate.
Bug fix: When restoring maximised main window it was sometime wider than before maximisation.
Bug fix: Fake “Ext” column could be shown by mistake.
Bug fix: Sorted On Exit Crash after long periods of use.

SSH core upgraded to PuTTY 0.56. It brings following changes:
- Security fix: the vulnerability reported by iDEFENSE is fixed. See details.
- Several other changes.
Added support for UTF-8 encoded filenames for SFTP protocol version 4 and newer.
WinSCP returns exit code 1, when any command in console mode is interupted due to an error or any prompt is answered Abort (even automatically in batch-mode).
Setup application can add WinSCP installation folder to search path (%PATH%). Thanks to Marco Barisione for his add_path tool.
New upload option Clear source file ‘Archive’ flag.
Command Open in PuTTY can optionally send password to PuTTY. When the option is on, the password must be kept in memory.
Usage of option --full-time with LS command is configurable (SCP only).
When the server does not support resolving symbolic links (SFTP version 2 and older), the double-click on regular file (possibly symlink) makes WinSCP try to open directory with the same name.
Removed no longer useful button Retry from “timeout” message.
Warning is shown when user stores session with filled password.
%XX in URLs are decoded. Plus sign (+) is converted to space.
New option to swap panels in Commander interface.
When LS command does not list anything, error messages are shown even if Ignore LS warning option is turned on (SCP only).
Added command Create directory to context menu of file panels.
Solved all compiler warnings when compiling WinSCP using makefile.
Bug fix: When SFTP server incorrectly replied with packet SSH_FXP_STATUS with “success” status, WinSCP tried to decode the packet as if it were packet of expected type in some cases.
Bug fix: Backspace changed to parent directory even during in-place renaming of file.
Bug fix: Missing quote in sample custom command File Compare.
Bug fix: Keyboard shortcuts for file selection (Grey */+/-) do not beep anymore.
Bug fix: Ctrl+C on message dialog has omited some new lines.
Other small changes and fixes.

Scripting/automation.
Custom commands enhanced:
- New pattern !& for remote commands to insert space separated list of selected files. Only one command per selection is executed. The pattern cannot be combined with pattern !. Sample command Tar/GZip now uses the pattern as well as new sample command Grep.
- New option Show results in terminal. Used by new sample command Grep.
- Custom commands can be executed locally on temporarily downloaded files.
- Local custom commands can be executed on pairs of remote (temporarily downloaded) and local files (Commander interface only). New sample command File compare uses the option. Replace simple fc command with your favourite diff tool.
New command-line parameters /synchronize and /keepuptodate. Both have two optional arguments for local and remote directory. If parameter is preceded by stored session name, it is opened automatically. Otherwise login dialog is shown.
For SCP protocol the directory is read with --full-time option to get second-precision timestamp (necessary for synchronization). When the reading of the first directory fails (for whatever reason), the directory is reloded without the option and the option will no longer be used. Next version will include option to control the behaviour manually.
“Host hasn’t answered for X seconds” message disappers itself once the response finally arrives.
WinSCP can be now compiled using Personal edition of Borland C++Builder 6.
New browsing shortcuts:
- Alt-Left and Alt-Rigth to browse backward and forward.
- Back/forward buttons on some mouses supported (Microsoft Intellipoint particularly).
- Support for Back, Forward, Reload, Home and Favorities buttons on multimedia-keyboards.
SSH core upgraded to current development snapshot of PuTTY. It brings following changes:
- Support for CHAP (digest-based) authentication when talking to SOCKS 5 proxies. Configures itself transparently (if the proxy offers CHAP it will use it, otherwise it falls back to ordinary cleartext passwords).
- Negotiated SSH-2 MAC algorithm(s) are mentioned in the Event Log.
- OSU_1.5alpha4 added to list of known servers with bug Chokes on SSH-1 ignore messages. Now it is possible to login to the server with the respective bug-option set to default value Auto.
- Several other bug fixes.
Bookmarks and location profiles changes:
- Buttons to switch between bookmark and location profile modes.
- Local path box has history drop-down.
- Reordering bug fixed.
Support for dd mmm yyyy format of ls command output (for example Mac OS X 10.3 Panther).
With SCP protocol -p option is used with cp command to preserve attributes when duplicating files.
Parameter /help shows command-line option overview.
For entering the initial remote directory the directory changes cache is not used to guarantee that the initial directory really exists on the server.
New popup menu for blank space on file panels with some common directory commands (reload, etc.).
Directory tree node automatically expands itself when selected.
Direction switch on synchronization dialog separated from other options to emphasise that its state is not stored, when Use same settings next time is checked.
Button Cancel on Cleanup application data dialog renamed to Close, so, when invoked during uninstallation, it does not make impression that it cancels the whole process.
Fixed bug in SCP protocol “dummy command” keepaliave mode.
Bug fix: If the option Preview changes was stored in preferences for Synchronize command, it affected incorrectly the Keep up to date command too.
Bug fix: When uploading using drag&drop, confirmation was required even when it was turned of.
Bug fix: For SFTP protocol, directory content cannot be read, if the server provides extended file attributes (e.g. IBM zOS).
Bug fix: Backslash in username caused bookmarks not to load.
Bug fix: Refresh command on disconnected session aborted the application.
Bug fix: On Windows XP the keyboard accelerators as well as focus rectangles and similar were not shown sometime. On the other hand, the system-wide option Hide keyboard navigation indicators until I use the Alt key is now ignored.
Bug fix: For SCP protocol, after cached directory change to no-longer existing directory, the file panel preserved its previous contents.
Bug fix: Initial state for Use the same settings next time check on Synchronize dialog was undefined.
Bug fix: When creation of local directory failed, no error message was displayed.
Bug fix: When download using drag&drop in Temporary directory mode finished while the computer desktop was locked, the download failed, and it was no longer possible to use drag&drop.

New function to duplicate remote files. Implemented natively only for SCP protocol as SFTP does not have the functionality. With SFTP the command can open secondary shell session, like with Open Terminal (and other functions), to perform the duplication.
Function to create new file and open it in default editor.
Remote recycle bin may be configured for session. Deleted and overwritten files may be optionally moved to defined remote directory.
During synchronization user may optionally request confirmation before each change.
Path label above file panel is now click-able. User may click on any part of the path to enter that directory (Commander interface only).
Size of the translation files reduced by 40% (more than 200 KiB each).
New filename modification option: lower case only DOS names (8.3).
On startup program checks for obsolete temporary folders. If it finds any, it offers user their deletion. Obsolete directories maybe also deleted manually from Cleanup window (see Tools button on Stored session tab of Login window).
Confirmation option Exiting application on operation completion affects now also, whether confirmation is shown once upload invoked using Windows Explorer’s Send to menu is finished.
When importing stored sessions from PuTTY, default values are used for options not set by PuTTY (like transfer protocol).
In file panel, when horizontal scroll bar is hidden, left and right arrow keys moves selection to first and last file respectively (Commander interface only).
Bug fix: With some specific devices, prompt to insert media was shown just before the main windows of application was displayed (Commander interface only).
Bug fix: The check for obsolete default translation files failed to display complete error message when the translation file was really very old.
Bug fix: When drive (like USB memory stick) was attached or detached the local directory tree was not refreshed, making the new drive inaccesible from local panel (Commander interface only).
Bug fix: Remote path history was corrupted, when directory was changed using directory tree.
Bug fix: Assertion error in attempt to use Desktop or My documents in local path drop-down menu.
Bug fix: Under specific circumstances application failed when closed, while having some editors still opened.
Bug fix: Error message was shown in infinite loop, when error occured in attempt to open file in an external editor.
Bug fix: Small problems with Kerberos authentication.
Bug fix: Local recycle bin could not be left using .. link (Commander interface only).
Bug fix: Setup failed to detect that the application is running during upgrade.

This security fix release is initially available in English version only. Other languages can be downloaded from downloads page once finished.
SSH core upgraded to PuTTY 0.55. It brings following changes:
- Security fix: the vulnerability found by the Core Security Technologies is now fixed. See advisory numbered CORE-2004-0705
- General robustness of the SSH-1 implementation has been improved.
- Bug fix: Random noise generation was hanging some computers and interfering with other processes’ precision timing.
- Several other bug fixes.
Multiple files can be edited and/or opened at the same time. Modified files are uploaded back using background transfer queue. To revert to previous behaviour, see Editor settings.
With SFTP protocol, it is possible to open separate shell session to execute user-defined commands. The server must provide Unix-like shell and the shell must use same path syntax as SFTP session for this to work. This enables Open Terminal, Custom commands and command-line features in SFTP sessions (the shell session is opened automatically when they are used).
Experimental support for version 5 of SFTP. Currently it brings only better error reporting. In future the upgrade may allow file verification using MD5 algorithm. Note that as I do not know any server supporting SFTP5, the funtionality was not tested at all.
When obsolete translation file is found in WinSCP startup directory, warning is shown, as it may cause program not to work properly.
Command Open directory/bookmark added to panel context menu (Commander interface only).
Some SFTP error messages were clarified.
Temporary directory options moved from Drag&drop tab of Preferences dialog to Storage tab as the settings are actually used by other features as well.
Bug fix: Save toolbar button was sometime disabled, when it should not and vice versa.
Several other bug fixes.

Symbolic links on remote tree has “arrow” icon overlay.
Only session properties whose values are different from factory defaults are stored. It dramatically decreases space occupied by stored sessions in windows registry and/or INI file.
Remote directory whose parent directory was never visited can be dragged from remote tree now.
Warning about possible lack of space in temporary directory when using temporary directory download mode now shows total transfer size even if dragging directories.
When uploading new directory with SFTP, WinSCP does not look for partial upload files, which may slightly decrease upload time.
It is not possible anymore to duplicate file from local panel using drag&drop.
Bug fix: Keepalive interval could be set to 60 seconds only instead of intended 60 minutes.
Bug fix: Keepalive interval was not imported correctly from PuTTY sessions.
Bug fix: When using INI file as configuration storage, persistent directory changes cache was not loaded correctly.
Bug fix: Pressing “X” button on message boxes had unpredictable results. Now it has the same effect as pressing Esc key.
Bug fix: Change to file size due to text mode transfer was not reflected on transfer progress indicator.
Bug fix: Parent directory of directory dragged from remote tree was needlessly reloaded.
Bug fix: Several drag&drop fixes.

This beta is released in English version only.
Directory tree display. Available both for remote and local (Commander interface only) panels. The tree may be used as both source and target of drag&drop operations.
Function Keep remote directory up to date was completely remade:
- Subdirectories are now optionally synchronized (maximal number of subdirectories being watched is 62).
- Arbitrary two directories can be synchronized.
- Obsolete files may be deleted (optionally).
- Function is newly available in Explorer interface too.
Files matching given mask may be excluded from file transfer and synchronization.
Option New and update file(s) only to transfer files that either does not exist in the target directory or whose timestamp is greater than target file timestamp. Similar functionality has new button Newer only on overwrite confirmation dialog.
Local change drive down menu contains links to folders My documents and Desktop (Commander interface only)
Files copied to clipboard may be pasted both to remote and local (Commander interface only) panels. Keyboard shortcut is Ctrl-V.
When handling scp:// or sftp:// URL, which includes path without trailing slash, the file or directory it points to is downloaded. When path ends with slash, the directory it points to is opened (previous behaviour).
New option existing only for Synchronization.
Transfer resume confirmation may be turned off.
With SFTP, file permissions are explicitly set on the newly created directories, as at least OpenSSH ignores default permissions for new directories.
Program may “beep” when file operation lasting more than specified time is finished (see Environment tab of Preferences window).
Bug fix: After successful login, an error like “Directory ‘D:’ doesn’t exist.”, was displayed when first existing non-floppy drive was not valid. Typical configuration was no C: drive and empty D: CR-ROM drive.
Bug fix: Using Home directory function on remote panel corrupted “change directory cache”.
Maximal length of file masks was extended on all windows.
Ctrl-C on message window copies to clipboard the additional message (display-able via More button) as well.
Toolbar button Open directory/bookmark moved from Standard toolbar behind directory drop down menu on Address bar (Explorer interface).
Double click on path label above file panel opens Open directory/bookmark window (Commander interface only).
Tab Drag&drop of Preferences window moved from Environment to Transfer group.
Error “EAccessViolation” is now replaced with more meaningful “Invalid access to memory” to better distinguish it from “Permissions denied”.
Bug fix: Button No to all on overwrite confirmation dialog made error message appear for every skipped file with SCP protocol.
Bug fix: Processed files were not deselected, when downloading using drag&drop and, when uploading using drag&drop from local to remote panel of Commander interface.
Bug fix: Message “Operation was successfully completed. Connection was closed….” was displayed as “Error” instead of “Information”, when uploading files from Sent to menu of Windows Explorer.
Bug fix: The local directory was uselessly reloaded sometime, when calculation of total transfer size before download was completed (Commander interface only).
Bug fix: With path a/bbb/ccc, the one-letter-long folder a would not be displayed in change directory drop down menu.
Bug fix: Text mode masks history was not working on Preferences dialog.
Bug fix: With initial configuration, session settings on Bugs tab of login dialog was not loaded properly.

MIT Kerberos 5 GSSAPI authentication. Thanks to Vaclav Tomec
Password provided on-request during connection may be optionally reused for background sessions. See Preferences dialog.
Transfers on background may be set as default. Both using Use same settings next time check and on Preferences dialog.
When disconnecting, alert shows up, when there are pending background transfers.
A hack that forced “copy” to be default transfer operation when using drag&drop shell extension has not proved to be reliable. As alternative solution, “move” operation is disabled now by default. It makes “copy” effectively the only possible operation and thus the default one. “Move” can be enabled on Preferences dialog. Note that “move” is always allowed when dragging inside WinSCP (e.g. from remote to local panel of Commander interface)
Background session opens directly in working directory of its first transfer. It saves one useless directory retrieval.
Server/protocol information window shows SSH implementation string.
Bug fix: When creating symbolic link with SFTP, symlink name was swapped for target name. As all OpenSSH SFTP servers has the bug as well, the bug is preserved when connected to OpenSSH SSH server (there no way to know provider of SFTP server).
Bug fix: Connection via proxy server has not worked at all in 3.6.
Bug fix: When downloading, modification timestamp was not preserved sometime. For example on Win2k, when using background transfer.
Bug fix: Upload target directory was uselessly reloaded twice after background transfer completion (both by background session and main session). Now it is reloaded on background only.
Bug fix: Explorer interface hanged on startup with certain configuration.
Bug fix: Disconnect when complete on progress dialog have not worked properly during certain kinds of operations.
Bug fix: After changing path to full path of cached symbolic link, current path was shown as path to symbolic link instead of its target path.
Other minor bug fixes.

Background transfer queue. When option Transfer on background is checked on transfer confirmation dialog, the transfer is added to background transfer queue. Each background transfer opens own SSH session, which is reused by further transfers. Number of simultaneous background transfers can be limited (defaults to 2). Transfer queue list can be displayed on the bottom of main dialog. There is new Transfer/Background tab on Preferences dialog to control queue options.
New permissions bits may be set: Set UID, Set GID and Sticky bit. Permissions maybe entered also as octal number with 4 digits.
Selectable approach towards daylight saving time. As some servers (mostly on Windows) adjust file timestamp with start of DST and some not (Unix), there is new option Daylight saving time on Environment tab of login dialog to select between the two approaches. For backward compatibility, Windows-style approach (server does adjustment) is selected by default. But it will most likely change soon as Unix-style (client does adjustment) approach is maybe better, while more dangerous and difficult to implement.
When not using Drag&drop shell extension, dropping files outside of WinSCP defaulted typically to move operation (instead of usual copy). As this is out of control of WinSCP, there is new option Allow moving via temporary directory, which is turned off by default. It makes copy effectively the only possible operation and thus the default one.
Bug fix: Drag&drop shell extension failed to register on Windows 95/98.
Fixed moving remote files to different remote directory. With SCP move to dir moves files now to dir subdirectory of current directory instead of /dir in root directory. With SFTP Move to did not work at all with most servers.
WinSCP can optionally automatically reply with stored password to the first keyboard-interactive, TIS or Cryptocard prompt. The feature is on by default.
Overwrite confirmation query indicates, if local or remote file is being overwritten. It is particulary useful for synchronization.
Text mode transfers may be forced for files edited in external editor (Editor tab of Preferences dialog).
Move command removed from default custom commands. Tar/GZip added instead.
When copying current path to clipboard, new-line is not appended anymore. The same applies to copying name of one selected file.
With SFTP protocol directory comparison is always done with second precision.
With SCP protocol, when time portion of modification timestamp is unknown, only date is displayed (00:00 used to be displayed before).
Quotes around path to private key are stripped, which is necessary when exporting and opening session in PuTTY.
Skipped files are included in batch operation percantage completeness.
When resuming file transfer, resumed file size is not counted towards Total transfered.
Bug fix: Using password longer than 255 characters hanged the application. This fixes Denial of Service as reported by Luca Ercoli.
Experimental support for two SFTP extensions owner-group-query@generic-extensions and software@generic-extensions as proposed by Erwin Bolwidt
Improved server prompts (keyboard-interactive, TIS and Cryptocard). Prompt dialog is wider. If the prompt still does not fit, whole text is displayed when hovering mouse cursor over it.
When URL part after scp:// or sftp:// matches one of the stored session names, the session is used. This way you may setup default username and/or password for particular host by storing them to session with the same name as the host.
Uncheck all button on Cleanup dialog.
Improved Import from PuTTY dialog. New Un/check all button. Cached host keys may be optionally imported for selected sessions.
When opening remote file for writting, file size is sent to server giving it chance to allocate enough space on file system in advance (SFTP only).
Ctrl-Left and Ctrl-Right in directory input boxes stops on slashes too (in addition to usual spaces).
Synchronized browsing works properly even when changing directory by more than one level (for example via history drop down list).
Improved communication with drag&drop shell extension. Situations when the application timouts waiting for response from the extensions should be much reduced now.
Local file, which is being written during download can be opened (for reading only) by other applications.
Local file opened by other application for writting can be uploaded.
Default text (ASCII) transfer mode file mask was modified to include *.*html and *.htm, instead of *.*htm*, which matches for example even file.html.zip.
When Drag&drop shell extension is enabled, but it is not found when dragging starts, error is displayed.
Command containing spaces only cannot be executed (SCP only).
Default custom commands translates with language change as long as they are not modified.
Bug fix: When dropping files, while mouse cursor indicated “drop denial”, file transfer was initiated regardless with unexpected results.
Bug fix: Change to logging options was reflected by active session only.
Bug fix: Appearance of status bars was corrupted when main window was resized (WinXP only).
Bug fix: When uploading back modified file, which was temporarily downloaded to be executed/opened, text mode was incorrectly used.
Bug fix: Fixed bug in SFTP4 implementation, when reading nano-seconds precision timestampts.
Bug fix: Symlinks in current directory are resolved with SFTP4.
Bug fix: Fixed generation of group drop down list on Attributes dialog in case the server does not provide it (SCP only).

Default drag&drop operation, when transferring to local directory, is “copy”, when shells extension is used.
When session is closed as result of Disconnect when operation finishes option, the message dialog asks whether to close whole application or not. The confirmation may be turned off forcing application to close immediatelly.
Bug fix: When dropping on local directory with right mouse button, menu is displayed allowing to choose copy or move operation. The selected operation was ignored.
WinSCP checks for correct version of translation plugin.
When uninstalling user has option to cleanup the data stored by WinSCP.
File permissions are set explicitly after upload. It should fix problem on some SFTP servers that do not update permisions, when file existed already before transfer, but with other permissions.
For SFTP, when Set permissions is off, resume support is enabled and target file already existed, then permissions of the original file are applied to uploaded file after it is renamed from temporary filename (.filepart extension).
Option Closing session on confirmation box of Preferences dialog renamed to more appropriate Exiting application.
WinSCP now supports translation to languages unknown to Windows (Esperanto particularly).
Bug fix: Pageant and PuTTYgen components in setup application were switched.
Bug fix: When moving remote files to other directory, the file names were not displayed on progress dialog.

Drag&drop control completely remade:
- WinSCP setup installs Windows shells extension (file dragext.dll) that allows direct drag&drop downloads. The extension is loaded to memory on computer startup, even when WinSCP is not running! Use with caution.
- Drawback of the extension is that with it, files can be downloaded using drag&drop only to regular local folder of Windows Explorer. From Preferences windows, user can switch back to older mode that allows downloads to any destination (ZIP archive, FTP, etc.). However when using it, files are downloaded to temporary directory first.
- When dropping with right mouse button, menu is displayed allowing to choose copy or move operation.
- When dragging files within remote panel, only “move” operation is allowed and only if dragging to subdirectory or parent directory.
- When the shell extension is not used and files are moved using drag&drop outside of WinSCP, warning is displayed. The warning can be turned off from Preferences window via option Warn when moving to temporary directory. The option replaces older option Allow move on remote side.
- When dragging between local and remote panel, “copy” operation is offered by default (Commander interface only).
- Bug fix: When moving files to remote directory from local panel (Commander interface only) using drag&drop, local panel is refreshed after transfer completes.
Moving remote files to different remote directory.
SSH core upgraded to PuTTY 0.54. It brings following changes:
- Fixed validation of SSH-2 RSA key whose length was not a multiple of 8 bits.
- Several other bug fixes.
Program can be registered to handle scp:// and sftp:// addresses. Format of the address may be the same as session command-line parameter of program: (scp|sftp)://[user[:pwd]@]host[:port][/path]. Command-line parameter may also start with protocol name now. Address handling may be registered either from Preferences window or from setup application.
On Commander interface, command line panel can be shown. It allows execution of commands both on local and remote computer.
New function Copy Path to Clipboard copies current path to clipboard as text. Function is available from context menu of panels (Commander interface only) and from main menu.
New submenu File names in File(s) menu contains functions for manipulation with names of selected files: Copy to Clipboard, Copy to Clipboard (Include Paths) and Insert to Command Line (Commander interface only).
Minimize button on synchronization progress window.
Synchronized browsing is preserved, when restarting application and switching session, as long as the last component of local and remote path is the same.
Empty SFTP directory listing packet is considered to indicate end of directory listing. While it seems to be vilation of SFTP protocol, it was implemeted to support some older SFTP servers.
Synchronization options can be saved.
Preserve timestamp option is forced on for function Keep remote directory up to date.
When updating of timestamp after file upload fails, program suggests to turn off Preserve timestamp option (SFTP only).
Swapped month name and day number is allowed in directory listing (SCP only).
Ctrl+Alt+H hot key toggles showing of hidden files in panels (corresponds to Show hidden files option on Preferences window).
When local panel is selected, synchronize dialog offers remote directory synchronization by default and vice versa (Commander interface only).
Menu Mark has new Select/unselect item. Its purpose is solely to show new users, who do not know Commander interface, keyboard shortcut to select/unselect files.
Directory bookmarks is the default bookmark management option for Commander interface. It used to be “Location profiles”.
When server fails to read requested number of bytes with SFTP protocol when reading file, error “Received incomplete data packet before end of file” should not occur any more for most of the cases. However in such circumstances, acceleration of SFTP transfer performance introduced in 3.4 is lost.
When renaming temporary .filepart file to destination name fails, program suggests turning off the “resume support”.
When program fails to initialize SFTP protocol due to “Received too large SFTP packet”, it offers possible solution.
Server time zone offset can be set up to +/- 13 hours with 15 minutes precision.
Edited file is uploaded, when its timestamp changes randomly, not only when it changes forwards. This fixes problem that remote file, whose timestamp was forward comparing with local time, was not uploaded after beging edited.
Bug fix: Changes to loaded stored session on login dialog were saved when Login button was pressed.
Bug fix: Failure when selecting directory on remote panel drop down menu.
Bug fix: Path above remote panel is shortened when it does not fit to panel width (Commander interface only).

Installation package includes Czech, Finnish, French, German, Hungarian, Italian, Japanese, Malay, Polish, Spanish and Swedish translations. More languages will be available once completed.
Full local and remote directory synchronization. Either both directories can be synchronized or one of them only. When only one directory is synchronized against the other, files/directories not existing in the other directory can be optionaly deleted.
New session option Cache directory changes. Together with Cache visited directories it allows instant changes to already visited directories without talking to the server. For SCP protocol the cache has no benefit without Cache visited directories being turned on as well. Cached directory changes can be preserved between sessions (Permanent cache option). Both caches can be cleared using Commands > Clear caches command.
For uploads and downloads operation masks can be used. Operation mask is used to change the filename. By default mask *.* is offered, which leaves filename unchanged.
When the total transfer size is calculated, the operation progress dialog shows time estimated till completion.
During download, return code 1 of scp command is ignored. Among other things, this allows continuation of batch file transfer after some non-serious errors.
Server/protocol information window (in Commands menu).
When the first command line parameter is not session name, WinSCP parses the parameter using pattern [user[:pwd]@]host[:port][/path] and tries to open the session.
Session can be kept alive alternativelly by executing dummy command.
Overwrite confirmation dialog shows size and modification timestamp of both files.
SFTP (with SCP fallback allowed) is now default transfer protocol.
Both upload and download confirmation dialogs has target path histories.
For downloads, file properties modification and calculation of total transfer size, symlinks to directories are not followed.
Size of SFTP packet is limited by maximal size of SSH-2 packet (as suggested by the server). This heuristics can allow WinSCP to work on SFTP servers with limited memory (in particular servers running on embeded devices).
Local read-only files can be overwritten (confirmation is required).
When PuTTY is not found in configured (or default) path, the search paths (PATH system variable) are searched for executable.
Open in PuTTY opens existing session from PuTTY’s session list, when session with the same name as current WinSCP session exists.
File having CR/LF line endings already is not converted, when converting line endings from LF to CR/LF.
Empty output of groups command is tolerated.
When neighter configured local directory nor user documents directory can be opened, the WinSCP installation directory is set as initial in the local panel of Commander interface.
When saving modified session, name of original session is offered as default name.
Download confirmation dialog forces full local (non UNC) path to be entered.
SSH core upgraded to current development snapshot of PuTTY (2003-12-22). It brings following changes:
- Some memory leaks fixed.
- SOCKS4/5 proxy fixed.
- Bug fix: Connections to 127.0.0.1 from interface IP addresses was refused.
Operation progress percentage is now shown on progress window title too.
Command Quit was moved from Commands to File menu of Explorer interface.
Sort direction arrows on file panels are reversed.
Changes to directories with names like ~ xxxx are again possible. Note space after tilde (SCP only).
The history management of edit boxes histories was changed. The old histories from previous versions will not be loaded.
The first stored session is now always selected on login dialog to show the focus.
Bug fix: When user denied to overwrite remote file in uploaded directory, superfluous error message was displayed (SFTP only).
Bug fix: There were one second time difference on 50% of downloaded files (SFTP only).
Bug fix: When the server refused to provide the directory listing the last opened directory listing was still displayed even when actual path was changed (SFTP only).
Bug fix: Fatal error during upload crashed the application (SCP only).
Bug fix: Stored sessions tab was not selected in navigation tree (on the left of Login dialog) when session was saved.
Bug fix: Failure when error occurs while closing remote file after upload itself failed (SFTP only).
Bug fix: Failure while uploading empty file in text (ASCII) mode.
Bug fix: When none of the SSH authentication methods was aggreed with the server, meaningless and errorneous prompt for password was displayed.
Bug fix: Violation of SFTP4 specification, when opening remote file (4 bytes instead of one were occupied by parameter type of SSH_FXP_OPEN packet).

Bug fix: Incorrect SFTP upload of files in text-mode (Shame on me, I had a bad week).
Bug fix: Proxy options Consider proxying local host connections and Do DNS name lookup at proxy end were set incorrectly, when session was loaded on login dialog.
Translation support improved.
Russian and Czech translations updated.

Serious bug fix: Uploaded files smaller than 4 KiB were empty after transfer (SFTP only).
Russian translation of setup application added.

Significant acceleration of SFTP transfer performance.
WinSCP can be translated to other languages. Currently, there are Czech, Japanese, Russian and Spanish translations complete. More translations are in progress. Setup application itself is not translated to Russian yet. To use Russian translation, install Russian translation and switch to it using Languages button on login dialog.
New pattern for custom commands: !?prompt?default!. When command with this pattern is executed, user is first asked for value of prompt parameter (default is used as default value).
New predefined custom command Move (mv “!” “!?&Move to:?!”), using above new pattern.
Every custom command has two switches: Apply to directories and Execute recursively.
Paths like ~username, when changing current directory, are now handled with SCP protocol.
New option on copy confirmation dialog: Append button (SFTP protocol only). When selected, user has two options. Either to append source file to end of destination file or to finish transfer. The latter option is another kind of transfer resuming and is particulary useful for updating log files. The option is not available, when source file is smaller than destination file.
Debug informations and additional checks (assertions) were removed from executable. This may lead to small performance benefits.
Support for version 0 and 1 of SFTP (SSH File Transfer Protocol). With these versions, rename and resume features are disabled.
Total transfer size of all files in batch operation is calculated. This enables correct calculation of operation progress percentage. As the total size calculation can last too long, it can be turned off on Preferences dialog.
Prompts (usually for password) issued by server as part of TIS, Cryptocard or keyboard-interactive authentication methods are distinguished from password authentication prompts issued by WinSCP itself.
Remote directory(ies) properties dialog has new button Calculate, which calculates total size of all files in directory(ies).
Batch operation progress percentage is shown on taskbar.
Drive drop-down menu is updated, when a drive/device is loaded or ejected (Commander interface only).
Time or size or both can be used to compare files (Commander interface only).

Default resume threshold increased to 100 KiB.
Function Check for updates is available on login dialog too.
When uploading file in text (ASCII) mode, ^Z (ASCII 0×26) characters are removed.
Button Save (session) is available on all tabs of login dialog, with exception of Stored sessions tab.
Insignificant errors that occur during reading directory content with SFTP protocol are ignored.
Local panel is resorted, when file is renamed (Commander interface only).
More descriptive error message is shown, when SCP protocol cannot be initialized (SCP command is missing or cannot be found).
Preferences dialog uses navigation tree instead of tabs, just like Login dialog.
Bug fix: Fixed error with canonizing paths with SFTP protocol. On some servers, this error caused failure, while uploading directories.
Bug fix: Download option Preserve read-only now works with SFTP protocol.
Bug fix: Change to word wrapping with editor being opened is now applied correctly.

Exclamation mark (!) in command is replaced with name of file. There are two predefined commands: touch (touch “!”) and execute (“!”). To execute custom command use either main menu or remote file context menu.
New option Continue on error (for advanced users only). When the option is on and error occures during batch operation (transfer, delete, set properties, etc.), the batch is not stopped. At the end of operation list of errors is displayed.
For SCP protocol it is possible to define time zone difference between server and client. Using this information WinSCP is able to perform correct remote and local directory comparison.
Check for updates feature. It connectes to WinSCP site and checks, if there is new version released. You may also run WinSCP with command line switch /update.
New option Do not change local directory when switching sessions. It preserves same local directory, when switching between opened sessions (Commander interface only).
Current session settings can be exported to PuTTY and opened with this SSH terminal client (Ctrl-P).

With SFTP4 it is also possible to change file owner/group.
With SFTP4 WinSCP is compatible with VanDyke VShell for Windows.
Directory bookmarks were replaced with Location Profiles in Commander interface. Profile is composed of both local and remote directory bookmark and custom name. Profiles can be organised into folders (currently one level only). Profiles are compatible with bookmarks in both ways. To switch back to bookmarks, see check box on Commander tab of Properties dialog.
SSH core upgraded to current development snapshot of PuTTY (2003-07-17). It brings following changes:
- Two new proxy options: Consider proxying local host connections and Do DNS name lookup at proxy end (see Proxy tab of login dialog).
- New SSH server bug detection: Misuses the session ID in PK auth (see Bugs tab of login dialog).
- Several bug fixes.

Version of SFTP in use is displayed on status line of main application window.
On Stored sessions tab of login dialog, you may add item to Windows Explorer’s Send to menu. The item opens session and uploads selected files.
All icons and shortcuts that may be created using installer can be created also on Integration tab of Preferences window. This includes desktop icon, quick launch icon and upload shortcut to Windows Explorer’s Send to context menu.
Option Resolve symbolic links on Environment tab of Login dialog. If it is turned off, symbolic links will not be resolved, when directory content is loaded. This may speed up directory loading and avoid problems with cyclic links. Yet it disables possibility to open symbolic links pointing to a directory and disables Add/edit link function.
On Properties window, it is possible to change file permissions even using octal format.
For external editor, it is possible to specify optional parameters. Pattern !.! is replaced with name of file being edited.
