Pi Review

Good to merge

This is a straightforward changelog entry addition — one new entry for Ansible repo ansible.cfg support, following the exact pattern of all existing entries. No code logic changes, no new public surfaces, no concerns.

Test coverage

CI / workflows / docs / config-only — no automated tests expected, and none are needed for a static data file update.

Mergeable, but should ideally address nits: broken changelog link

Found 1 issue:

1. [P2] Broken changelog link
   frontend/src/lib/components/sidebar/changelogs.ts:10

   The newly added sidebar changelog entry points to https://www.windmill.dev/changelog/ansible-repo-ansible-cfg, which returns HTTP 404 on both HEAD and GET. Adjacent existing changelog links in this same file return HTTP 200, so this appears specific to the newly introduced slug. Users clicking the new entry will land on a missing page unless the slug is corrected or the page is published before merge.

Test coverage

Frontend/docs-link-only change; no automated tests are expected for this changelog array entry.

Manual verification still needed: open the changelog entry from the sidebar and confirm it navigates to a published changelog page rather than a 404.
