  (:issue:`4021`, :issue:`4228`)

- Move ``Channel`` and subclasses into ``nfd::face`` namespace

- Improve consistency of logging in channels (:issue:`2561`)

- Change ``ndn-autoconfig`` tool to register ``/`` prefix instead of ``/ndn`` (:issue:`4201`)

- Documentation improvements

Bugfixes
^^^^^^^^

- In ASF strategy add check for FaceInfo existence before using it (:issue:`3968`)

- Avoid setting TransportState to FAILED if connection is closed cleanly (:issue:`4099`)

- Fix regression ``ndn-autoconfig`` continue proceeding with existing face (:issue:`4008`)

- Decode ``CachePolicy`` without requiring ``allowLocalFields`` (:issue:`3966`)

- Fix support for link-local IPv6 addresses (:issue:`1428`)

- Fix potential misaligned memory accesses (:issue:`4191`)

Removals
^^^^^^^^

- Deprecated code, including ``faces/enable-local-control`` and ``faces/disable-local-control``
  management commands (:issue:`3988`)

- ``NetworkInterfaceInfo`` class, replaced by ``ndn::net::NetworkInterface`` from ndn-cxx
  (:issue:`4021`)

- Legacy nfdc and nfd-status invocations

  The following legacy nfdc sub-commands are deleted, use the corresponding ``nfdc face ...``,
  ``nfdc route ...``, ``nfdc strategy ...`` commands:

  * ``register``
  * ``unregister``
  * ``create``
  * ``destroy``
  * ``set-strategy``
  * ``unset-strategy``
  * ``add-nexthop``
  * ``remove nexthop``

- ``nfd-status`` no longer accepts command line arguments (:issue:`4198`).  Individual datasets
  can be requested using ``nfdc channel list``, ``nfdc face list``, ``nfdc fib list``, ``nfdc
  route list``, and ``nfdc strategy list`` commands.

- ``nfdId`` from ``nfdc status`` output (:issue:`4089`)

- Prohibited endpoint set, making it possible to create faces that connect NFD to itself
  (:issue:`4189`)
