1. Changed: In our plugin systems, we have many factory functions that create objects and returned raw pointers; in many but not all places, these returned raw pointers were then converted to std::unique_ptrs. This has been changed now by (hopefully) consistently letting factory functions return std::unique_ptrs right away, and then dealing with them at the receiving end.
