This is a C++ library where the most trivial changes can break binary
compatibility.   Interface changes won't if they only comprise
additional non-virtual methods, otherwise they will.  Having no
interface changes will still break compatibility if class membership
changes.

Anyway, on looking at the patch there are no interface modifications of
any kind, nor change of class membership, so we look to be OK.
