New features:

  • UI: it is now possible to upload TLS certificates to the server directly from the UI, using a specific selector in the Security page of the protocols configuration.
  • UI: the maximum amount of characters in all text controls has been limited to a sensible number, so to avoid potential crashes or stalls in corner cases.

  • Server: The version number in the welcome messsage can now be manually suppressed by setting the "has_version" attribute of the message field in the configuration file to "false".
  • MSW: If the service is running under the SYSTEM account, configuration files are now placed under %PROGRAMDATA%\filezilla-server. This is to workaround the issue that when doing a Windows Update the settings could be wiped out. Settings still residing under %LOCALAPPDATA%\filezilla-server are automatically migrated.

  • Mac: fixed regression that made the installed service not startable
  • Admin UI: changed wording in the logging settings
  • Admin UI: made default connection values correct, in case the settings file is missing.

1.4.0-rc1 (2022-04-20)

Fixed vulnerabilities:

  • MSW: the installer doesn't rely on the PATH environment variable to find the tools its needs, but refers to them absolutely, to avoid hijacking.

New features:

  • The size of the TCP buffer sizes on the sockets used for data transfers can now be specified
  • Configuration files are now tagged with a "flavour" and a version number. The Server will refuse to load configuration files with a different flavour than its own or with a version higher than its own. The server's option --config-version-check can be used to control this functionality: if specified, the server checks the versioning, performs the required action and then exit, unless its action is 'ignore'. If the action is 'error', it just checks whether the versions are ok. If the action is 'backup', then a backup of the files is made if the versions are not ok. The parameter --config-version-check-result-file is used to specify a file in which the result of the version check has to be put. If the file contains 'ok', then everything went file. If the file contains 'error', then there was an error. If the file contains 'backup', then a backup was made. The installer makes use of this functionality.
  • Admin UI: the selected log entries can now be copied to the clipboard, in CSV, HTML and plaintext formats through the context menu
  • Admin UI: the settings dialog layout has been changed to accomodate for future other protocol settings, factoring out the settings that are common to all protocols.
  • Admin UI: adjusted borders and spacing to look better on HiDPI displays.
  • Admin UI: preserve the fingerprints of the previously connected servers. The connection dialog gives hints when inputing the host and port.
  • Log files can optionally be rotated daily instead of by size
  • Added option to specify a default user to impersonate if a user logs in with an account that does not use impersonation

Bugfixes and minor changes:

  • MSW: The installer not detects and rejects 32bit Windows
  • MSW, Admin UI: No more double error message when a validation error occurs

  • Admin UI: the system user is now always at the top
  • Admin UI: more meaningful message if the password is empty
  • Admin UI: message dialogs now always have a reference to the top window
  • FTP: QUIT needs to respond with 221, not 200

  • Mountpoints are now impossible to rename or delete.

New features:

  • The configuration files can now be reloaded without shutting down the service first. To make it work, send the SIGHUP signal to the service process on nix, send the paramchange control message to the service on Windows (i.e. 'sc control filezilla-server paramchange').
  • The UI now automatically attempts to reconnect to the server if the connection is lost
  • MSW: users are now case-insensitive
  • Mac: created an installer
  • Display the administration TLS certificate fingerprints at installation time, so that they can be taken note of.
  • Negotiate custom ALPN with FileZilla Client, this allows saving a few round-trips during connection establishment

Bugfixes and minor changes:

  • Warn if no administration password has been given during installation.
