2.2.0

Major changes:

• Field names reflection. Added new constexpr boost::pfr::get_name<N, T>() function that returns a std::string_view with a name of field at index N of an aggregate T. Requires C++20. BOOST_PFR_CORE_NAME_ENABLED is defined to 1 if the functionality is available. Many thanks to Denis Mikhailov, Bela Schaum and X-Ryl669 for the PR PR#129 and implementation ideas.

• for_each_field() is now constexpr for C++17. Many thanks to Alexander Karatarakis for the PR PR#134.

2.1.0

Major changes:

• Implemented the boost::pfr::is_implicitly_reflectable and the machinery for specializing aggregates as reflectable or not, thanks to Denis Mikhailov for the #111.
• Implemented boost::pfr::get by type of an element in the aggregate.
• Implemented the BOOST_PFR_ENABLED macro to detect library support for reflection, thanks to Denis Mikhailov for the PR #86.
• Workaround for broken C++17 stuctured binding in old compilers, thanks to Denis Mikhailov for the PR #119.

2.0.3

• Added missing #include <memory> for inclusion of std::addressof
• Fixed -Wzero-length-array warning when dealing with empty aggregates
• Fixed compilation on msvc compilers <= 1920 (thanks to Alexey Romanov aka @alexey-romanov)
• Added basic CMakeLists.txt support (thanks to @pdimov aka Peter Dimov)
• Multiple improvements for docs, including links to https://github.com/apolukhin/pfr_non_boost
• Added misc/strip_boost_namespace.sh script to remove boost:: and BOOST_ prefixes

2.0.2

• A MurMur Hash based implementation of hash_combine() is now used to reduce collisions count and improve quality of boost::pfr::hash_value()
• Visual Studio 2017 now supported in C++14 mode (thanks to Denis Mikhailov aka @denzor200)
• Issues found by inspect tool were fixed
• Fixed some warnings, including removal of extra semicolons in include/boost/pfr/detail/fields_count.hpp (fixes #72)
• Added a compile time assert for inherited types (thanks to Denis Mikhailov aka @denzor200)
• Reflection of aggregates with non movable fields is now possible if guaranteed copy elision is on
• Fixed spelling issues

2.0.1

• Comparison functions are now constexpr
• Aggregates with members that have lost const qualifiers on SFINAE in constructor (like std::optional<std::chrono::duration<A,B>> from libc++) now could be reflected again
• Multiple typos fixed
