- Convert scoped_ptr to std::unique_ptr from <memory> - Convert arraysize to base::size from include/base/cef_cxx17_backports.h - Convert NULL to nullptr - Include include/base/cef_callback.h instead of include/base/cef_bind.h - Implicit conversion of CefRefPtr<T> or scoped_refptr<T> to T* is gone; use .get() instead See the issue for additional details.
