Version 5.6.0, 2024-10-29

Security Fixes

The embedded OpenSSL library in SFTPPlus has been updated to version 3.3.2. [#6770]

New Features

SFTPPlus now supports the symmetric SSH cipher algorithms aes256-gcm@openssh.com and aes128-gcm@openssh.com. [client-side][server-side][sftp] [#5468]
You can now configure an AS2 location to receive asynchronous MDN messages. [client-side][as2] [#5400]
The user interface for the event details view in the Activity log has been updated [#6179]
The AS2 location can now be configured to send compressed files. [client-side][as2] [#6756]
You can now duplicate/clone an existing transfer using the Web Manager GUI. [manager] [#6774]
The AS2 server now supports signatures that are advertised to use the sha256_rsa algorithm name. This is an alternative name for the rsassa_pkcs1v15 algorithm, which implements PKCS#1 v1.5 signatures. [server-side][as2] [#6775]
The AS2 location can now be configured to use the GET method to test the availability of the remote AS2 server. [client-side][as2] [#6817]
On the Web Manager login page, you can now configure a short information box to provide additional usage or Terms of Service information. [manager] [#6833]
The HTTP REST API used by the SFTPPlus web server is now available as an OpenAPI version 3.1 YAML file. [server-side][http][https] [#6856]

Defect Fixes

The help text for the Authenticate Peer Certificate TLS configuration from Web Manager has been updated to indicate that the default value is now set-on-first-connection. [manager] [#4099]
The AS2 server now returns the errors as MDN messages. In previous versions, an HTTP 400 Bad request response was used to signal an error. [server-side][as2] [#5794]
The Windows Share / SMB location no longer raises the STATUS_BAD_NETWORK_NAME error when configured with an invalid path, such as when using backslash path separators. [client-side][smb] [#6239]
When using an Exchange Online location, if there is an error retrieving the list of attachments for an email that has just been removed, the email is now ignored. An error was raised in previous versions under such circumstances. [client-side][exchange-online] [#6601-2]
When an HTTP request fails, the error now includes specific HTTP information. In previous versions, an internal server error message was used instead of a specific HTTP error. [client-side][http] [#6601]
On Windows, the limit of total concurrent opened files was increased to 2048. [windows] [#6770]
When the SFTPPlus server sends asynchronous MDN messages, it now sets the Content-Type HTTP header to indicate that the content is a MDN message. In previous versions, the Content-Type header was set to application/octet-stream instead of multipart/signed. [server-side][as2] [#6775-1]
When the SFTPPlus server sends asynchronous MDN messages, the message that the AS2 file was successfully received is emitted only after the MDN message has been successfully delivered. [server-side][as2] [#6775]
The AS2 service can now receive signed files with the signature stored in binary format. [server-side][as2] [#6778]
When uploading files to Azure Files, the paths configured using backslashes as separators (Windows path separators) are automatically converted to forward slashes (Unix path separators). Previously, the Azure Files cloud server accepted backslash-separated paths. Following a recent update, only forward-separated slashed are now supported. [client-side][azure-files] [#6811]
When sending AS2 files, the MDN message returned by the remote AS2 server no longer needs to contain the "Original-Recipient" or "Final-Recipient" headers. [client-side][as2] [#6817-1]
The AS2 location now includes the AS2-From and AS2-To headers when making the HEAD or GET requests to test the availability of the remote AS2 server. In previous versions, the request was made without any extra headers. [client-side][as2] [#6817]
The AS2 transfers can now receive AS2 messages from certificates that have the serial number as one of the components of the subject field. [server-side][client-side][as2] [#6818-1]
The AS2 transfer can now receive AS2 messages for which the multipart boundary option name is defined in uppercase. [server-side][client-side][as2] [#6818]

Deprecations and Removals

Alpine Linux 3.12 is no longer supported. We recommend using an Alpine Linux version with upstream support, currently Alpine Linux 3.17 or newer. [#6770]
