Release Notes

ndn-cxx version 0.6.6

Release date: April 27, 2019

Note that this is the last release that encodes to NDN packet format version 0.2.1. A future release will continue to decode v0.2.1 format, but will encode to v0.3 format.

New features:

  • More support for NDN packet format version 0.3 (issue #4527)
    • Support new naming conventions to encode/decode segment numbers, byte offsets, versions, timestamps, and sequence numbers based on typed name components (issue #4777)
    • Stop using ChildSelector in CertificateBundleFetcher (issue #4665)
  • NDN_THROW macro to throw exceptions including file position and runtime context of the throw statement (issue #4834)
  • Ensure that a Block with TLV-TYPE zero is treated as invalid (issue #4726, issue #4895)

Improvements and bug fixes

  • Avoid directly using memory address as PendingInterestId to prevent potential false removal of an entry (issue #2865)
  • Follow up packet specification changes to rename the Parameters element to ApplicationParameters and to change its number to be a non-critical element type (issue #4658, issue #4780)
  • Add option to disable infrastructure interest in CertificateFetcherDirectFetch (issue #4879)
  • Fix compilation against recent versions of Boost libraries and issues with Xcode 10.2 and older versions of Boost libraries (issue #4890, issue #4923, issue #4860)
  • Improve the “CanBePrefix unset” warning (issue #4581)
  • Improve documentation


  • PendingInterestId, RegisteredPrefixId, and InterestFilterId types in favor of PendingInterestHandle, RegisteredPrefixHandle, and InterestFilterHandle (issue #4316, issue #3919)
  • Block::empty in favor of Block::isValid (with inverted semantics)
  • Scheduler::scheduleEvent and Scheduler::cancelEvent in favor of Scheduler::schedule and EventId::cancel (or use ScopedEventId to automatically cancel the event when the object goes out of scope) (issue #4883)
  • ndn::util::Scheduler (use ndn::Scheduler or ndn::scheduler::Scheduler) and ndn::EventId (use ndn::scheduler::EventId) (issue #4883)
