That is everything since Halden 4.5 in June.
- A product changelog or release notes page grouped by month.
- Release notes with type filters such as features, fixes, and improvements.
- Changelogs that should offer an email subscribe action in the header.
- Use timeline for a short vertical list of events without filters.
- Use accordion for plain expandable content that is not dated.

Usage
Use this for a product changelog page. Load entries from your release notes source and connect the subscribe control to your mailing list.
import { ChangelogFeed } from "@/components/arc/blocks/changelog-feed/changelog-feed"; export default function ChangelogPage() { return ( <main> <ChangelogFeed /> </main> );}ChangelogFeed
Release notes grouped by month, with type filter chips, expandable entries with media, a month jump nav, and an inline subscribe form. Entries, images, and the webhook snippet are sample data.
No props.
- Escape
- Cancels the subscribe form and returns to the Subscribe button.
- Each entry row is a button with aria-expanded and aria-controls pointing at its detail panel.
- Filter chips are toggle buttons with aria-pressed, and the visible count is announced in a polite status region.
- The month nav marks the current month with aria-current, and the scroll area is focusable with an aria-label.
- Entries open in place on a spring while the chevron rotates; the month label slides in the scroll direction.
- The subscribe control morphs from button to form to a drawn check with a short blur crossfade.
- Reduced motion makes these changes instant.
- Below 640px the header stacks, rows move date and type above the text, and the scroller drops from 560px to 520px.
- Below 480px month counts and the shown count are hidden so the month nav fits on one line.
- Hover styles apply only on hover-capable fine pointers.
- The feed scrolls inside a fixed-height area; entries are not virtualized, so paginate or load older months on demand.
- Scroll tracking for the month bar is batched to one requestAnimationFrame, and a ResizeObserver resyncs it on resize.
Notes for AI
Give your coding assistant the Markdown reference instead of screenshots.
- Use for a product changelog or release notes page.
- Replace the entries array and the imported sample images with data from your release notes source or CMS.
- The subscribe submit only changes local state; post the email to your mailing list provider.
