- Twine, StringRef, Format, and NativeFormatting have been removed - Logging now uses fmtlib style formatting - Nearly all uses of wpi::outs/errs have been replaced with fmt::print() or std::puts()/std::fputs() (for unformatted strings). - A wpi/fmt/raw_ostream.h header has been added to enable fmt::print() with wpi::raw_ostream
