  -Added the HomepageTimer to the new composable Home Page
  +The homepage `<Header />` is now part of the composable canvas (allowing you to add the <HomepageTimer />, for example).
  +
  +You will need to wrap your existing composed `<HomePage />` component in `<Page />`, `<Header />`, and `<Content />` components, like this:
  +
  +```diff
  +// app/src/components/home/HomePage.tsx
  +
  ++ import { Content, Header, Page, HomePageTimer } from '@backstage/core-components';
  +
  +export const HomePage = () => (
  ++ <Page themeId="home">
  ++ <Header title="Home">
  ++ <HomepageTimer />
  ++ </Header>
  ++ <Content>
  + <Grid container spacing={3}>
  + <Grid item xs={12}>
  + <HomePageSearchBar />
  + </Grid>
  + // ...
  ++ </Content>
  ++ </Page>
  +);
  +```
