- CefURLRequest::Create is no longer supported in the renderer process (see https://crbug.com/891872). Use CefFrame::CreateURLRequest instead. - Mac platform definitions have been changed from `MACOSX` to `MAC` (see https://crbug.com/1105907) and related CMake macro names have been updated. The old `OS_MACOSX` define is still set in code and CMake for backwards compatibility. - Linux ARM build is currently broken (see https://crbug.com/1123214).
