We are happy to announce a release candidate of the Mule SFTP Transport 2.2.1 which is targeted for Mule 2.2.1. New features:

• Added support for connection pooling (SFTP-6)
• Added sftp specific server notifications (SFTP-11)
• Added support for identity files (authentication using keys, not password)
• Added fileAge support (that is, a miniumum age (ms) for a file to be processed
• Added archive support (stores a copy of the file on the Mule server)
• Added duplicate handling support (throwException, addSeqNo, overwrite[not yet implemented])
• Added temp directory support – The file is first uploaded to a temporary directory. When the file is fully uploaded the file is moved to its final destination. The tempDir will be created as a sub directory to the endpoint. Other significant changes:
• Updated the path-handling to be spec-compliant (SFTP-13). Note, this probably mean that current users must update their paths.
• Fixed so that the file in the inbound directory is not deleted if some error occurs when writing to the outbound directory
• Improved error information regarding connection-related errors.
• Upgraded jsch from 0.1.29 to 0.1.42
• Bug fix: SFTP transport doesn’t work with the Quartz transport (SFTP-9)
• And other small fixes…’ Project URL: http://www.mulesoft.org/display/SFTP/Home
