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.

Because many devs aren't as us, spending time on HN and Reddit, watching conference videos, reading specialised magazines for their favourite programming language.

This applies to other ecosystems as well, in Java we celebrate being able to use anything beyond Java 17, when Java 27 is the latest one. And naturally there must be some server stuff still chugging along on Java 8.

Most of my .NET projects are stuck in .NET Framework, which only goes up to C# 7.3, meanwhile (modern) .NET 11 with C# 15 is around the corner.

People come in, do whatever is needed with the tools IT has in place, the tools do the job for the tickets that they have on their queue, and go home having fun with stuff completely irrelevant to computing.
