Version 0.4

As of this version, NDN Essential Tools require a modern compiler (gcc >= 4.8.2, clang >= 3.4) and a relatively new version of the Boost libraries (>= 1.54). This means that the code no longer compiles with the packaged version of gcc and Boost libraries on Ubuntu 12.04. NDN Essential Tools can still be compiled on such systems, but require a separate installation of a newer version of the compiler (e.g., clang-3.4) and dependencies.

• Fix compilation error with new version of ndn-cxx library
• Avoid use of deprecated block helpers
• Correct build target path

ping:

• Recognize and trace NACK
• Fix potential divide-by-zero bug in StatisticsCollector (Issue #3504)

peek:

• Recognize and properly handle NACK
• Refactor implementation

Version 0.3

chunks: New (pair of) tool(s) for segmented file transfer

peek:

• Allow verbose output

Version 0.2

Code improvements and two new tools:

• PIB service to manage the public information of keys and publish certificates (Issue 3018)
• A Wireshark dissector for NDN packets (Issue 3092)

Version 0.1

Initial release of NDN Essential Tools, featuring:

• ndnpeek, ndnpoke: a pair of programs to request and make available for retrieval a single Data packet.
• ndnping, ndnpingserver: reachability testing tools for Named Data Networking.
• ndndump: a traffic analysis tool that captures NDN packets on the wire.
• ndn-dissect: an NDN packet format inspector. It reads zero or more NDN packets from either an input file or the standard input, and displays the Type-Length-Value (TLV) structure of those packets on the standard output.
