- As part of the ongoing STL header dependency cleanup, the following
breaking changes related to @ref std::string, @ref std::vector and
@ref std::pair are done:
- @ref DebugTools::FrameProfiler::measurementName() and
@ref DebugTools::FrameProfiler::statistics() now return a
@relativeref{Corrade,Containers::StringView} /
@relativeref{Corrade,Containers::String} instead of a @ref std::string
- @ref GL::AbstractShaderProgram::validate() now returns a
@relativeref{Corrade,Containers::Pair} with a
@relativeref{Corrade,Containers::String} instead of a @ref std::pair
