+### Minor version vs patch version
+
+Increase the patch version if only the following changes are included.
+
+- Update the `@latest` version of the tool.
+
+  Rationale: Normally, tool versions are controlled by the `@<version>` syntax, which is explicitly separated from the versioning of the install-action itself.
+
+  Exception: If the major or minor version of the `cargo-binstall` is updated, the minor version should be increased because the behavior of the fallback may change slightly.
+
+- Fix regressions or minor bugs.
