ndn-cxx version 0.4.0

Release date: December 31, 2015

Note

Version 0.4.0 introduces several breaking changes to API and wire format of management protocols

Changes since version 0.3.4:

New features:

• (breaking change) LocalControlHeader for special signaling between application and NFD has been replaced with NDNLPv2 signaling (issue #2879, issue #2930)
• NDNLPv2 Network NACK support in Face abstraction (issue #2930)
• (breaking change) FacePersistency field added to API and wire format of ControlParameters abstraction (issue #2991)
• (breaking change) NACK counters added to ForwarderStatus and FaceStatus datasets (issue #3174)
• Backport C++14 std::make_unique (issue #3093)
• Emulate std::to_string on platforms that do not provide it (issue #2743)
• New API in Face class to remove all pending Interests (issue #3300)
• Ability to choose signing parameters (a specific certificate, the default certificate for a key, or the default certificate for the default key) using a specially URI string (issue #3281)
• Ability to create Face with custom IO service and default transport (issue #2500)

Improvements and bug fixes:

• (breaking change) SegmentFetcher helper changed to use asynchronous data validation (issue #2734)
• Support Interest Nack in nfd::Controller (issue #3264)
• Fix bug causing failure of Face if there is a large delay between construction of Face and calling processEvents (issue #2742, issue #2526)
• Cache Link object after the first call to getLink (issue #3158)
• Minor documentation updates (issue #3207, issue #3210, issue #3221)

Deprecated:

• Overloads of Face::registerPrefix and Face::setInterestFilter that do not accept SigningInfo parameter (issue #2932)
• tlvdump tool (issue #3196). Use ndn-dissect program from ndn-tools repository https://github.com/named-data/ndn-tools
• ndn::util::makeDummyClientFace, use ndn::util::DummyClientFace constructors directly (issue #3146)
• ndn::util::DummyClientFace::sentDatas, use ndn::util::DummyClientFace.sentData instead (issue #3146)

Removed:

• Deprecated EventEmitter class (issue #2351)

Planned features for future releases:

• Introduce new API to simplify security transformations (issue #3009)
• NDN trust schema as a description of application trust model, which can help automate data and interest packet signing and authentication (issue #2829)
• Refactored KeyChain abstraction (issue #2926)
