Boost 1.75.0 Release With JSON, LEAF, and PFR Libraries

Boost 1.75.0 Release

This latest Boost 1.75.0 release C++ library has been announced with the newly added JSON, LEAF, and PFR libraries.

Boost is a collection of free peer-reviewed, open-source, and portable C++ source libraries that work well with the C++ Standard Library. Boost is also an important source for additions to the Standard C++ Library as adopted by the C++ Standards Committee.

Highlights of the Boost 1.75.0 Release

First off, it is good to note that Boost.Operators is currently incompatible with C++20 compilers. it is known that in some cases may manifest as an infinite recursion or infinite loop in runtime when a comparison operator is called.

This is caused by the new operator rewriting behavior introduced in C++20. As a workaround, users are advised to target C++17 or older C++ standard.

The following are the new libraries that come with Boost 1.75.0 release.

  • JSON by Vinnie Falco and Krystian Stasiowski: This library brings JSON parsing, serialization, and DOM in C++11.
  • LEAF by Emil Dotchevski: This is a lightweight error-handling library for C++11.
  • PFR by Antony Polukhin: This is a Basic reflection without macro or boilerplate code for user-defined types.
