ndn-cxx version 0.6.5

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 (4527)
  - Stop using ChildSelector in NotificationSubscriber (4664)
  - Stop using ChildSelector in CertificateBundleFetcher (4665)
- Support floating point numbers in TLV-VALUE (4612)
- Scoped prefix registration, scoped Interest filter, and scoped pending
  Interest (3919, 4316)
- Counters for satisfied and unsatisfied Interests in ForwarderStatus
  (4720)
- random::getRandomNumberEngine() in the public API
- MetadataObject class to encode/decode RDR-style metadata (4707)
- SegmentFetcher::stop() (4692)

Improvements and bug fixes
==========================

- Use openssl-based routines for the PKCS#8 decoding/decryption when
  exporting key from macOS Keychain (4450)
- Switch to AES-256 for private key encryption in PKCS #8 export
- Add exponential backoff in CertificateFetcherFromNetwork (4718, 4712)
- Throw exception when loading an orphaned ValidationPolicyConfig (API
  violation) (4758)
- Forbid unrecognized TLVs before Name (4667)
- Prevent memory pool size from becoming zero in InMemoryStorage (4769)
- Clean up fetchers when destructing nfd::Controller (4775)
- Fix SegmentFetcher undefined behavior caused by uncanceled pending
  interest (4770)
- Seed the PRNG with more entropy (4808)
- Stop accepting NonNegativeInteger as sequence number in NDNLP (4598)
- Backport C++17 std::any and std::variant as ndn::any and ndn::variant
- Reimplement scheduler::EventId with CancelHandle (4698)

Deprecated
==========

- ndn-cxx/util/scheduler-scoped-event-id.hpp header as it is now
  sufficient to use ndn-cxx/util/scheduler.hpp header (4698)
- Implicit conversion from nullptr to scheduler::EventId (4698)

Removed
=======

- ndn::ip::address{,V6}FromString
- SegmentFetcher::fetch (4464)

- Headers that were already considered internal implementation details
  have been explicitly moved to a detail/ subdir to more clearly
  separate private and public headers
