🖼️ v0.15.1 — Live Previews in Release Notes

What's New

Nothing new in the public API — this is a documentation and tooling patch.

What Changed

bin/generate-release-notes — embed Lookbook previews in changelogs

The release notes generator now instructs Claude to check for a Lookbook preview class for every new or updated component mentioned in a release, and to embed it directly in the changelog using the ERB helper. If the preview class defines a playground method, that is preferred; otherwise the most illustrative method is used. Example:

<lookbook-embed
  app="https://midwest.unabridged-staging.com/lookbook/"
  preview="Elements::RatingComponentPreview"
  scenario="playground"
   panels="params"
  actions="inspect,open"></lookbook-embed>

Older changelogs backfilled with embed helpers

Live component embeds were retroactively added to four earlier changelogs so readers get interactive previews regardless of which version they're browsing:

• v0.12.0 — AccordionComponent, PaginationComponent, EmptyStateComponent, ProgressBarComponent, ConfirmationComponent
• v0.12.1 — ConfirmationComponent
• v0.13.0 — ChartComponent (area, column, and line playground embeds)
• v0.13.1 — ButtonComponent, Form::InputComponent

What Was Removed

Nothing removed.
