+All PRs that change the public API of `rust-bitcoin` must include a patch to
+the `api/` text files. This should be a separate, final patch to the PR

+API text files
+==============
+
+Each file here lists the public API when built with some set of features
+enabled. To create these files run `../contrib/check-for-api-changes.sh`:
+
+Requires `cargo-public-api`, install with:
