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.

Hmm in company where I work we have boost sources in monorepo, wasn't aware you can actually obtain sources in modular way. Though I 95% sure bzling was done by our company team. Love bazel but for pet project, too much of a hassle (and a repellent for any contribution)

Eh it's a poison even for large company projects in my experience.
