For us, it practically only changes the fact that `A<A<int>>` is now used instead of the C++03 compatible `A<A<int> >`. Note: clang-format 10+ changed the `Standard` arguments to fully specified `c++11`, `c++14`, etc. versions, but we can't use `c++17` now if we want to preserve compatibility with clang-format 8 and 9. `Cpp11` is still supported as deprecated alias for `Latest`.
