Poem

A rabbit nudges the changelog bright,
3.4.0 hops in, with links made right.
We wave to 3.9, a gentle goodbye,
and test on 3.14 beneath the sky.
Docs are tidy — carrot crumbs in sight.

🔇 Additional comments (3)

CHANGELOG.md (3)

12-15: Release header and upgrade note look good; verify the UPGRADING anchor exists.

• Check UPGRADING.md contains a matching ## 3.4.0 anchor resolving to #340.
• Confirm the date matches the actual release day if the tag slips.

---

140-141: Unreleased and 3.4.0 link updates LGTM.

Links align with existing style (compare for Unreleased; tag for release).

---

49-52: Historical entry polishing looks consistent.

Rewording/reordering across 3.3.0, 3.2.0, and 3.0.0 reads clean and preserves meaning.

Also applies to: 65-69, 120-133
