New Features

  • Audiobook support

From version 8.1 onwards Twonky Server supports the separation of audiobooks and music. If properly tagged, audiobooks are detected through metadata. If audiobooks cannot be detected based on metadata (e.g. not properly tagged), the user can also define shares that only contain audiobooks. Audiobooks are listed in the Music navigation tree in a separate node, called “Audiobooks”. Within this node, audiobooks are sorted by categories like artist, genre, or title.

Audiobooks are recognized by the following metadata:

    • ID3v1 tags with the genre “Audiobook” (value 183)
    • ID3v2 tags with the genre(s) configured by the ini file option "audiobookgenres" (case insensitive)
      • the Twonky Server settings pages allow to easily configure this list based on the genres found in the metadata of the shared music collection
    • import of an iTunes database containing items tagged as “Audiobook”

This feature does not only allow to browse more easily through audiobooks, but also enables client devices/applications to avoid shuffle and provide a resume function as demonstrated in the updated webUI and in the Twonky Ref App. When beaming audiobooks, the resume feature also depends on the renderer capability to play from a certain position. Some clients, e.g. WD, do not support seek and as such cannot resume.

When a renderer queue is enabled, normally all items are appended to the queue. In case of audiobooks, the queue is first emptied before the audiobook tracks are queued.
Please note that within the folder navigation audiobooks are treated like music items.


  • Significant performance improvements over earlier versions
    • Initial scan time improved by up to 30%; individual scan time depends on content loaded. Largest improvements are seen with heavily tagged image files
    • Adding items into the navigation tree of the server has also been improved, contributing to the overall scan time improvement and also improve restart behavior
    • Restart performance improved by 68% over latest 7.2 version of Twonky Server
  • TLS 1.2 support
  • support for block-cipher in TLS for online services like Dropbox
  • added ini property escape_json to configure escaping of JSON feeds
  • "disablemf" no longer available as INI parameter - "disablemf=1" to be replaced with "enablereporting=0"

  • dc:date is now provided in long format YYYY-MM-DDThh:mm:ss, if available and the client device can cope with the information
  • default value "1" for number of discs property removed as this led to odd results like disc 5 of 1
  • disabled HTTPS/TLS support as default on all platforms as this is not utilized
  • enhanced security for scripting access to Twonky Sever (new INI setting)
  • file scanner now estimates the framerate of an MPEG video, when this is not present in the metadata
  • file scanner now handles .dv .m4p .ogm .jps file extensions
  • file scanner now handles subtitle files .stl and .pjs

  • improved MKV-parser to find additional metadata
  • improved client adaptation for Naim devices
  • improved embedded albumart extraction for mp3 files and very large album arts
  • it is now possible to aggregate the "Mediatomb" server
  • list of servers available for aggregation is much faster updated
  • minimized the file eventing threads for Linux to optimize memory usage
  • multiuser db is now recreated in case current multiuser db could not be read
  • performance improvement when accessing audio file's album art
  • removed property res@bitrate for video files as the semantics are undefined (video bitrate or audio bitrate or ...)
  • server managed directories are now by default created in the user's home directory on Linux systems
  • signature of database is now always verified when server is started to avoid unnecessary database rebuilds when updating the Twonky Server
  • web UI
    • web UI and settings pages can now be enabled/disabled separately (added new INI param "enablewebui")
    • web UI: the beam/play icon is now only displayed if there is at least one item in the container
    • webUI now contains a link to online release notes
