Changelog33: Month Index Changelog

A changelog grouped by month with an index down the left: each month scrolls the page to its group, and the index follows along as you read.

Installation

Swap YOUR_EMAIL and YOUR_KEY for the email and license key on your account. Find your license key on your account page.

Radix flavor

npx shadcn add "https://ui.beste.co/r/changelog33?email=YOUR_EMAIL&license_key=YOUR_KEY"

Base UI flavor

npx shadcn add "https://ui.beste.co/r-base/changelog33?email=YOUR_EMAIL&license_key=YOUR_KEY"

This installs the block to components/beste/block/changelog33.tsx plus the button22 sliding-marker pill and the text1 word stagger it uses.

Quick start

The installed file exports changelog33Demo alongside the block: the exact props behind the preview above. Spread it to get a working page in one line.

import { Changelog33, changelog33Demo } from "@/components/beste/block/changelog33";

export default function Page() {
  return <Changelog33 {...changelog33Demo} />;
}

Then replace the demo with your own props. Written out, a trimmed setup looks like this:

import { Changelog33 } from "@/components/beste/block/changelog33";

export default function Page() {
  return (
    <Changelog33
      eyebrow="Changelog"
      heading="Month by month."
      description="Small releases, often. Pick a month or scroll through the year."
      buttons={[{ label: "Follow by email", href: "/updates", tone: "outline" }]}
      months={[
        {
          label: "September 2026",
          entries: [
            { date: "5 Sep", title: "Yearly pricing", changes: ["Monthly and yearly switch", "Seat calculator"] },
          ],
        },
      ]}
    />
  );
}

Props

type Entry = {
  date: string;
  title: string;
  changes: string[];
};

type Month = {
  label: string;
  entries: Entry[];
};

type ActionButton = {
  label: string;
  href: string;
  tone?: "primary" | "light" | "dark" | "outline";
};

Behavior notes

• Index entries call scrollIntoView on a ref held per month, and pass behavior: "auto" under reduced motion so the jump is instant rather than animated.
• The active month is tracked with onViewportEnter on each group using a tall negative viewport margin, which fires when the group crosses the middle of the screen rather than its edge.
• That tracking viewport has no once, unlike the entrance animations, because it has to keep firing as you scroll back and forth.
• Groups carry scroll-mt-24 so a jump lands below a fixed header rather than under it. Match that to your navigation height.
• The index is sticky and vertical from the large breakpoint, and wraps into a horizontal row below it, so it stays usable on a phone without pinning.
• The short rule beside the active month is a width transition rather than a transform, so it grows from the text rather than scaling out of it.
• Entries use day-level dates because the month is already the group heading, which keeps the left column narrow.
