New features, changes and fixes

FileSystem for .NET

• Added: Ability to filter out symbolic links, junctions, volume mounts, etc (name surrogate reparse points) from being scanned and processed for zipping.

Xceed Zip for .NET

• Changed: It now takes less time to create and update zip archives (excluding compression) that contain a large number of items.

Xceed SFtp for .NET

• Added: Popular encryption modes aes256-ctr, aes192-ctr aes128-ctr, 3des-ctr for increased interoperability and security. Also added arcfour, arcfour128 and arcfour256 for situations where a little encryption strength can be sacrificed for greater processing speed.
• Changed: No longer requests file locking by default on SFtp version 6 servers. Locking can now be controlled manually.
• Changed: On the .NET framework v4 and later, AES encryption now uses a FIPS-compliant implementation.
• Bugfix: Timeout occurred with servers that use low data window values.

Xceed FTP for .NET

• Added: Ftp.NET now supports FXP over SSL/TLS connections.
• Bugfix: Calling Abort() when downloading did not always stop the file transfer.
