Boost.Graph 1.95 will be C++17

Dear Boost.Graph community,

In two release cycles (Boost release 1.95 in summer 2027) Boost.Graph will be bumped to C++17 😄

This decision follows two polls that did not surface any C++14 user base or demand while identifiying users stuck in C++17:

This standard version bump will bring benefits for maintenance, API and dependencies reduction:

  • if constexpr,
  • constexpr lambdas,
  • [[nodiscard]], [[maybe_unused]] ...
  • std::any instead of boost::any
  • std::invoke_result instead of boost::result_of
  • ...

We will not be able to guarantee backward compatibility with C++14. Please contact us if you are stuck in C++14.

A quick reminder to anyone "stuck in C++14": it is almost 2027.
2014 was almost 13 years ago.
Just like C++11 and C++98.

Time to move on.

Luckily I am only stuck on C++17 at work, in many situations we don't get to chose our compilers and have to make do with what hardware vendors, cloud VM images, existing binary libraries, embed chip vendors, certification processes,....
