There is no single answer to that. Every library maintainer decides for himself.

boost.asio is still pre-Cpp11?

I think so, I haven't seen notifications about it removing support for C++03. Obviously, some features require newer C++ version.

Then boost.context must still be Cpp03 because of the dependency of boost.asio to boost.coroutine....

It's worse than that - some libraries have varying use of C++03 up to C++20. If you ask "Does Boost support C++ ?? " then you are asking the wrong question. Boost does not have a concept of "support". Studying the individual library documentation and the continuously updated Boost test matrix will give you some clues. The only way to be absolutely sure is to try to compile with the C++ std version you hope for. Paul

Some are missing, you may check their respective docu and/or open an issue in their repos. To summarize: - Libraries decide on their own what they require - If Boost.X uses Boost.Y and Boost.Y requires C++11, then so does Boost.X (obviously) - Many libraries enable additional features on newer standards - The level listed on the above page list the minimum required for the library to compile/work at all FWIW: Using C++03 in 2021 is an anachronism. Seriously: Save yourself the pain and go to C++11 at least.

Along with what Paul explains you can check the library documentation page at https://www.boost.org/doc/libs/ for the C++ minimum mode a library supports. Library are free to support some of their functionality above their C++ minimum and should document the fact if they do. Libraries which have no "C++ Standard Minimum Level" field in the documentation page have chosen not to officially support a C++ minimum level for that library, although this usually means that the library supports C++03 and above.

It is still used by boost.asio.

"Ask ye not if Boost supports C++03, but rather if C++03 supports Boost." Thanks
