{{- /*

    Template to render a page with a `changelog` layout or the `changelog`
    section page. This conflation seems to be a limitation of Hugo currently, it
    uses this template for both cases.

    For the `changelog` section page, this redirects the page to the latest
    version's changelog page.

    For a page with a `changelog` layout, this adds a table at the top of the
    page with information about the release:

    * A link to the matrix-spec repository at the time of the release, with the
      version taken from the `linkTitle` in the frontmatter of the page, unless
      it is the unstable changelog.
    * The date of the release, taken from the `date` in the frontmatter of the
      page, unless it is the unstable changelog.
    * A link to the markdown checklist format of the changelog. The `outputs` in
      the frontmatter of the page must include `checklist`.
