Aspera is excited to introduce the major release of IBM Aspera Enterprise Server, Connect Server, Desktop Client, and Point-to-Point Client for Linux and Windows.  This 3.7.1 release provides the new features, fixes, and other improvements listed below.

New Features

  • Ascp

    • The performance of the FASP protocol has been enhanced. Compared to prior releases, unencrypted CPU-bound transfers may see an increase of up to 100% in overall throughput; and encrypted CPU-bound transfers may see an increase in overall throughput of up to 20%.
    • Resume mode checks in Ascp now use a SHA-2-based MD5 checksum algorithm by default
    • Ascp now features new complete include and exclude filter options to support glob and regular expression matching
    • A new FASP Manager API feature can be used to send an event when individual arguments
    • Ascp now includes a new asynchronous “in transfer” post-processing engine with Lua scripts
    • Parallel (multi-session) transfers initiated from the command line can now use a URI for the filepath


    • a4 now ships pre-installed in the bin/ directory of Enterprise Server, Point-to-Point, and Client
    • New options parallelize all file operations with a configurable number of threads for directory traversal and file attribute checking, as well as read/write
    • Transfers to AWS S3 and S3-compatible storages are now supported
    • a4 now includes support for all file resume, skip, and overwrite options of standard ascp
    • The preservation of file owner uid and gid (--preserve-file-owner-uid, --preserve-file-owner-gid) is now supported in a4
    • Support for FASP management APIs is complete
    • a4 features a new FASP Manager-I/O interface to support byte stream (“streaming”) transfers. This support includes stream-to-file and stream-to-object storage transfer over WAN at high speed
    • Transfers of empty directories, including to S3 APIs, are now supported
    • Transfers of sparse files are also now supported

    Node API

    • A new case-insensitive filter can return filename matches regardless of case to Aspera Files
    • The /ops/transfers API has been improved, including new support for setting transfer rates, bandwidth priorities, and pausing/resuming/canceling active transfers
    • Asperanoded includes improvements in the /info and / API response
    • /ops token authorization now uses SHA-2 as the default checksum, rather than SHA-1
    • The status of files and transfers can now be reported by iteration token from the Node API
    • File modification events, including delete and rename, are now logged to redis/scalekv
    • Default and allowed SSL ciphers have been updated to eliminate support for 3DES and to align the defaults with hardened versions
    • Users can now run asnodeadmin --db-update to migrate data from Enterprise Server 3.5.6 and earlier versions.
    • Asperacentral has a new raw options capability that allows users to authorize the use of raw format ascp options in raw format by configuring aspera.conf.

    Watchfolder and Aspera Watch Service

    • Reports state of asperawatchfolderd in addition to the state of the transport and state of the watch.
    • Users can now select an existing aspera watchfolderd service when creating a watchfolder.
    • Two new APIs for Watchfolder, one to start, stop, and manage asperawatchfolderd and asperawatchd (asperarund) and one to configure user access to specific instances of asperawatchfolderd and asperawatchd (access_control)
    • Support for force-send-after configuration for growing files
    • The configuration of asperawatchfolderd can be updated without re-sending the remote host password
    • Watchfolder can now retry failed drops
    • Many enhancements to the robustness of asperawatchfolderd
    • Encryption-at-rest is now supported
    • asperawatchfolderd now initiates transfers with a destination root, allowing Watchfolder transfers to work using the Aspera upload option for Akamai storage (requires a minimum server software version on the Akamai side).


    • Support for Access keys and storage roots to allow async to run on Aspera Files and other Node v4 apps
    • The new recursive mtime option enables the exclusion of directories and files older than a configured timestamp
    • A new asyncadmin option prints file attributes 
    • Pending file bytes are now reported correctly in Aspera Console during an async pull
    • New --delete-delay option allows the delete operations in a unidirectional sync to be delayed until the end of sync
    • New reporting by Shares user in Aspera Console

    Cloud Support

    • Supports HDFS and Cleversafe object storage with NetApp object storage support using its S3-compatible API
    • trapd can now connect to Swift cloud storage using a self-signed certificate
