It describes how statically linking extensions changed in DuckDB 2.0 and what builders on top of DuckDB need to do. This change is in ... he new C API. It applies even if you continue to build against the existing (v1) C API: the difference is in how extension archives are linked and registered, not in which API your bindings call.
