Version 0.5.6

- The build dependencies have been increased as follows:

  - GCC >= 9.3 or Clang >= 7.0 are strongly recommended on Linux; GCC
    8.x is also known to work but is not officially supported
  - Xcode 13 or later is recommended on macOS; older versions may still
    work but are not officially supported
  - Boost >= 1.71.0 and ndn-cxx >= 0.9.0 are required on all platforms

- Fix compilation against the latest version of ndn-cxx

- Fix building the documentation with Python 3.12

- Upgrade waf to version 2.0.27

Version 0.5.5

- The minimum build requirements have been increased as follows:

  - Either GCC >= 7.4.0 or Clang >= 6.0 is required on Linux
  - On macOS, Xcode 11.3 or later is recommended; older versions may
    still work but are not officially supported
  - Boost >= 1.65.1 and ndn-cxx >= 0.8.1 are required on all platforms
  - Sphinx 4.0 or later is required to build the documentation

- Switch to C++17

- Fix compilation against the latest version of ndn-cxx

- Stop using the gold linker on Linux; prefer instead linking with lld
  if installed

- Upgrade waf to version 2.0.24

Version 0.5.4

- The build requirements have been increased to require Clang >= 4.0,
  Xcode >= 9.0, and Python >= 3.6. Meanwhile, it is recommended to use
  GCC >= 7.4.0 and Boost >= 1.65.1. This effectively drops official
  support for Ubuntu 16.04 when using distribution-provided packages;
  ChronoSync may still work on this platform, but we provide no official
  support for it.

- Exceptions are now thrown using NDN_THROW instead of
  BOOST_THROW_EXCEPTION

- The private header files config.hpp, common.hpp, bzip2-helper.hpp,
  mi-tag.hpp, and tlv.hpp have been moved to a detail subdirectory

- Fix compilation against the latest version of ndn-cxx

- Fix incompatibility with the C++20 <version> header

- Upgrade waf to version 2.0.21

Version 0.5.3

- Schedule sync Interest when receiving a NACK with reason NoRoute
  (Issue #5012)

- Use properly seeded pseudorandom number generator from ndn-cxx

- Fix compilation against the latest version of ndn-cxx

- Upgrade waf to version 2.0.14 and other build system improvements

Version 0.5.2

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

- Transition to v0.3 packet format (Issues #4691 and #4684)

Version 0.5.1

- Fix forceful shutdown of `Face` when destructing `Logic` instance
  (Issue #4525)

- Fix compilation against the latest version of ndn-cxx library

- Upgrade `waf` to the latest version and other improvements

Version 0.5.0

- BREAKING CHANGE Use bzip2 compression of sync Data payload (Issue
  #4140)

- Disallow Interest loopback on sync prefix (Issue #3979)

- Avoid ABI differences between debug/optimized modes (Issue #4496)

- Extend Socket and Logic API:

  - Allow customization of sync interest lifetime (Issue #4490)

  - Limit the size of created sync Data and enable ability to customize
    the maximum packet size through environment variable (Issue #4140)

  - Allow override of the session number

- Disable use of Exclude filter (preparation for Exclude deprecation in
  NDN and implementation was only partially correct)
