ndn-cxx version 0.6.3

Release date: September 18, 2018

The build requirements have been upgraded to gcc >= 5.3 or clang >= 3.6, boost >= 1.58, openssl >= 1.0.2. This effectively drops support for all versions of Ubuntu older than 16.04 that use distribution-provided compilers and packages.

The compilation now uses the C++14 standard.

Deprecated

• SegmentFetcher::fetch() static functions in favor of start() (issue #4464)

• ndn::ip::address{,V6}FromString as Boost.Asio >= 1.58 has proper implementation of addressFromString

  NDN Packet Format v0.3 replaces Selectors with CanBePrefix and MustBeFresh elements. CanBePrefix and MustBeFresh are currently mapped to the closest v0.2 semantics and encoded as selectors.

• Data::get/setFinalBlockId() in favor of Data::get/setFinalBlock()

Removed

• Dependency on Boost.Regex in favor of std::regex
