NLSR version 0.7.0

Release date: August 18, 2023

New features

  • Add experimental support for State Vector Sync (SVS) (issue #5248)

  • nlsrc: Add an option to query the status from remote routers (issue #4544)

Notable changes and improvements

  • Deprecate ChronoSync support: ChronoSync support is now optional and excluded from the default build; it remains available mainly for testing purposes (issue #5147)

  • Switched to the C++17 standard

  • The minimum build requirements have been increased as follows:

    • Either GCC >= 7.4.0 or Clang >= 6.0 is required on Linux

    • On macOS, Xcode 11.3 or later is recommended; older versions may still work but are not officially supported

    • Boost >= 1.65.1 and ndn-cxx >= 0.8.1 are required on all platforms

    • Sphinx 4.0 or later is required to build the documentation

  • Refactor LSDB for readability and add signals to notify of modifications (issue #4127)

  • Retrieve LSA from the face that triggered the notification of LSA changes

  • Accommodate certificate name in KeyLocator (issue #5195)

  • Change sig-type to ecdsa-sha256 in nlsr.conf as ndn-cxx now has strict checking for it

  • Improve error handling and reporting

  • Stop using the gold linker on Linux; prefer instead linking with lld if installed

  • Update waf build system to version 2.0.24

  • Various test suite and documentation improvements

Bug fixes

  • lsdb: Fix for issues involving incorrect retransmission behavior in segment fetcher

  • Prevent NLSR from unregistering route during update for router that advertised it initially (issue #5179)
