- `extern` now requires `unsafe extern`, but in turn allows functions within it to be marked as `safe`. Add examples to both effects within the text, and update listing numbers accordingly. - `#[no_mangle]` now requires `#[unsafe(no_mangle)]` These are all backwards-compatible, so we can opt the chapter into using the new rules without issue.
