NFD version 24.07

Release date: July 28, 2024

Important changes and new features

  • The build dependencies have been increased as follows:

    • GCC >= 9.3 or Clang >= 7.0 are strongly recommended on Linux; GCC 8.x is also known to work but is not officially supported

    • Xcode 13 or later is recommended on macOS; older versions may still work but are not officially supported

    • Boost >= 1.71.0 is required on all platforms

  • Ubuntu 24.04 (Noble), Debian 12 (Bookworm), and macOS 14 (Sonoma) are now officially supported

  • Added an official Dockerfile to the repository. From this Dockerfile, the following images are currently published to the GitHub container registry:

    All images are available for linux/amd64 and linux/arm64 platforms.

  • The default Unix socket path changed to /run/nfd/nfd.sock on Linux and to /var/run/nfd/nfd.sock on all other platforms (issue #5304)

  • Introduced a new strategy trigger onInterestLoop that is invoked when a duplicate Interest is received. The default behavior (sending a Nack packet) remains unchanged except for the Multicast strategy, which will now suppress the Nack transmission in this case (issue #5278)

  • Multiple updates to the ASF forwarding strategy to more closely adhere to the behavior described in the published technical report (issue #5310)

  • The ASF strategy gained support for Nack propagation (issue #5311)

  • The default port number of nfd-status-http-server changed to 6380
