0.9.0

ndn-cxx version 0.9.0

Important changes and new features

• C++17 is now required to build ndn-cxx and when including any of its header files

• 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, two images are currently published to the GitHub container registry:

  • named-data/ndn-cxx-build
  • named-data/ndn-cxx-runtime

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

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

• On macOS, the default TPM backend is now tpm-file (the same as all other platforms)

• Interest::matchesData no longer considers MustBeFresh and FreshnessPeriod (#5270)

• Modernized several APIs to use std::string_view

• Added Interest::setApplicationParameters(std::string_view) and Data::setContent(std::string_view) overloads for convenience

• SegmentFetcher gained an option to omit MustBeFresh from the first Interest sent

• Moved DummyClientFace, Segmenter, and SegmentFetcher to namespace ndn

• Moved all Signal-related classes to namespace ndn::signal

Improvements and bug fixes

• Check the TLV type when constructing Name from Block
• Provide relational operators for FaceUri, to make it usable as a container key
• Generalize and simplify time::fromUnixTimestamp and time::toUnixTimestamp
• Prevent overflows in InterestLifetime and FreshnessPeriod (#4997)
• Make HMAC signing and verification compatible with OpenSSL 3.x (#5251)
• Better handling of large dates in ValidityPeriod (#5176)
• NetworkMonitor now ignore AWDL interfaces on macOS (#5074)
• Avoid dependency on boost_program_options when tools are disabled (#5210)
• Add fine-grained options to ./waf configure to enable/disable the compilation of benchmarks, integration tests, and unit tests independently
• Fix building the documentation with Python 3.12 (#5298)
• Reduce amount of debugging information produced in compiled binaries by default (#5279)
• Update waf build system to version 2.0.27
• Various code cleanups, modernizations, and documentation improvements

Deprecations

• Face::getIoService(). Use Face::getIoContext() instead.
• Component::fromEscapedString(). Use Component::fromUri instead.
• TPM unlock and related functionality. This includes Tpm::isTpmLocked(), Tpm::unlockTpm(), Tpm::isTerminalMode(), Tpm::setTerminalMode(), and the ndnsec-unlock-tpm command-line tool (#4754)

Removals

• Block::wire(). Use Block::data instead.
• Component constructors that take a raw const uint8_t*. Use the span-based constructors instead.
• Component::fromImplicitSha256Digest() and Component::fromParametersSha256Digest()
• Previously deprecated overloads of Name::append()
• Name::push_back(). Use Name::append instead.
• ndn::escape() and ndn::unescape() overloads that take raw strings as const char* + size_t. Use the corresponding std::string_view versions instead.
• ndn::optional and ndn::variant. Use C++17 std::optional and std::variant directly instead.
• ndn::to_string(). Use the standard C++ function std::to_string() instead.
• Previously deprecated ndnsec command aliases (#5163)
