🐰 A rabbit's note on docs so fine,
Express paths now aligned in line,

Middleware order, never fear!

This changelog hopping feels so sweet! ✨

182-220: Clear and accurate Express v4.x / v5.x compatibility documentation.

The new subsections effectively document the differences between Express v4.x and v5.x for the authentication callback setup. Both code examples are syntactically correct and properly show the distinction: v4 requires the external body-parser package, while v5 has built-in urlencoded() middleware. The explanatory text is helpful for users upgrading or choosing between versions.

⚠️ Potential issue | 🟡 Minor

Wrap bare URL in angle brackets to comply with markdown lint (MD034).

The bare URL should be wrapped in angle brackets: <https://github.com/node-saml/node-saml/blob/master/CHANGELOG.md#v400-2022-10-28> to satisfy the no-bare-urls linting rule.
