Changes since version 0.2.0:

New features
^^^^^^^^^^^^

- **Build**

  + The code now requires C++11.  The minimum supported gcc version is 4.6, as earlier versions
    do not have proper support for C++11 features.

- **Faces**

  + Enable detection of WebSocket connection failures using ping/pong messages (:issue:`1903`)

  + In EthernetFace:

    * Avoid putting the NIC in promiscuous mode if possible (:issue:`1278`)

- **Management**

  + Add config file-based strategy selection (:issue:`2053`)

    The sample config file now includes strategy selection for ``/``, ``/localhost``,
    ``/localhost/nfd``, and ``/ndn/broadcast`` namespaces as follows:

    ::

        tables
        {
          ...
          strategy_choice
          {
            /               /localhost/nfd/strategy/best-route
            /localhost      /localhost/nfd/strategy/broadcast
            /localhost/nfd  /localhost/nfd/strategy/best-route
            /ndn/broadcast  /localhost/nfd/strategy/broadcast
          }
        }

  + Implement Query Operation in FaceManager (:issue:`1993`)

    (:issue:`1954`)

  + Display detailed NFD software verion in ``nfd-status-http-server`` and ``nfd-status``
    (:issue:`1916`)

  + ``nfdc`` now accepts FaceUri in all commands (:issue:`1995`)
