We are pleased to announce the latest release of SFTPPlus, version 3.7.0.

Here is the list of the important new functionalities:

• The OpenSSL version distributed in our Windows version was updated to OpenSSL 1.0.2g.
• The SSH protocol was updated to support hmac-sha2-256, diffie-hellman-group14-sha1, and diffie-hellman-group-exchange-sha256.
• SFTP and SCP server-side file close operations now emit dedicated event ids. In this way you can filter file upload or download operations based on a specific event ID. The previous event with ID 30017 is now used only when the file was not opened in read-only or write-only mode. [SFTP][SCP]
• Allow simple negation of the regular expression used in source filter. In this way you don't need to use look-around zero-length assertion regex rules to exclude a certain pattern.

This release was focused on reducing the number of known defects and improving the quality of the product. Here is the list of the main defects fixed in this release:

• The SCP server-side implementation now sends a response for successful SCP initialization, before starting to process the SCP transfer requests. This fixes a bug in which the Cisco SCP client (SSH-1.99-Cisco-1.25 implementation) hangs when SCP is initialized. For example when running copy start scp://10.0.2.1/some-file.
• Allow using the file dispatcher with any event from the file-operation group. Previously only the FTP upload events were supported. [#3366]
• Fix parsing the SCP arguments for client sending command line arguments with leading spaces. This affect the integration with the SCP client available on Cisco ASA and ASAv systems.

These are just the highlights of this release. For more details, including the full list of changes, please see the full release notes.
