+## 1.30.2
+**`(fix):`** Fix Basic Auth header not being sent when the username is an empty string.
+Per RFC 7617, an empty user-id is valid in Basic Auth (e.g., `:password`).
+The condition in `ToHeader()` now uses `||` instead of `&&`, so the
+Authorization header is set whenever either the username or password is
+non-empty.
