I checked each entry against its PR and the code at this PR's head.

Confirmed:

• All 28 referenced PRs are merged to master, none were reverted, and none duplicate the 0.22.0/0.22.1 sections.
• All links match their PR numbers, and every section is in PR-number order.

Most of the inline comments come with a suggested fix:

• Inaccurate or incomplete entries: gh-2206, gh-2290, gh-2291, gh-2322, gh-2324, gh-2382, plus the gh-2273 C-API functions.
• Missing content: the release summary paragraph and the Maintenance/CI items.
• A question about the NumPy runtime minimum (gh-2192).

Thanks for the updates. Everything from the earlier round is addressed. A few wording nits are inline.
