feat(release): update notes lead with up to 7 highlights - #28593

Eligibility
Release notes now show up to seven highlights and a count of other fixes, with corresponding desktop display updates. The change is limited to release communications and retains the full changelog and generation fallback.

Additional Thinking

Your Custom Policy

Default approvability criteria apply. The change alters release-note content and presentation, not product defaults, and the supplied diff adds no diagnostic-suppression directives; neither additional human-review condition is triggered.

Code

Changes release-note generation from paragraphs and fixes to up to seven structured highlights plus remaining fix/performance counts. Updates desktop parsing, IPC's optional footer, sidebar presentation, and documentation. Existing OpenAI use remains; structured decoding, commit-reference validation, GitHub changelog retention, fallback, and atomic file publication limit consequences to release-note content and display. Three customer-ignored files were not reconstructed.

Review Context

The author is an admin and ping-devs member; this provides context, not an approval exemption. The supplied complete review-thread check contains no unresolved comments or correctness findings. No check results or blocking-severity configuration were supplied. Investigation confirmed the generator's validation, fallback, and atomic publication behavior.

Verdict

The understood change is confined to generating and displaying release communications. It does not change deployment behavior, permissions, persistent customer data, or product defaults. Existing fallback and full-changelog retention limit the consequences of summary generation failures, leaving no obvious material risk requiring human judgment.
