Flexible FTP server (or Daemon) for all 32-bit versions of MS-Windows (Windows 2000 (Advanced) Server, 2000 Professional, Windows XP Home / Professional, Windows Server 2003, Windows Vista).

+ Added Japanese help translation.
+ Updated Japanese Management Console strings.
+ Added tray notifications for trial expiration and update period expiration.

- Corrected an SSH bug with the SSH_MSG_CHANNEL_REQUEST command where Serv-U was ignoring the "want reply" parameter and always sending a reply, causing some SSH clients to become confused.
- Corrected an SSH bug with the SSH_FXP_REALPATH_FMT command where Serv-U was always returning a directory, instead of the real path for a file path.
- Corrected an SSH bug when trying to list a directory that doesn't exist.
- Corrected an SSH bug where strings were not being UTF-8 encoded and decoded.
- Corrected a problem when uploading large files via SSH, an SSH packet could be missed causing the upload to stop.
- Corrected a problem with the upgrade notice (from versions prior to 7.0) where Asian installations were unreadable due to the use of an incorrect font.
- Corrected a problem with the log filter where it would not update the log with the filtered content correctly.
- Corrected a bug where FTP Voyager JV would receive an incomplete directory listing of large directories while operating in SSL mode.
- Corrected a bug where reseller PNG footer logos were not visible in IE6 or less due to the width and height not being set for the images.
- Corrected a bug in the "FTP Settings" tab under "Limits & Settings" of the Management Console where check boxes for commands with Advanced Options did not properly initialize their values to reflect the current state of the option.
