{# 

The `script` tag below facilitates a forward based on a URL hashtag. For example, as of writing:

- `/download/releases/v8-0-0/#latest-patch` autoforwards to `/download/releases/v8-0-6/`
- `/download/releases/v8-0-0/#latest-minor` autoforwards to `/download/releases/v8-1-5/`
- `/download/releases/v8-0-0/#latest-major` autoforwards to `/download/releases/v9-0-1/`

If there isn't a new patch/minor/major then it just becomes a noop when you add the respective hash to the URL

#}
<script>
const latest = () => {
    const lower_hash = window.location.hash.toLowerCase(window.location.hash);
    {% if new_patch %}
    if (lower_hash == '#latest_patch') {
        window.location.href = '{{ latest_patch_url | safe }}';
    }
    {% endif %}
    {% if new_minor %}
    if (lower_hash == '#latest_minor') {
        window.location.href = '{{ latest_minor_url | safe }}';
    }
    {% endif %}
    {% if new_major %}
    if (lower_hash == '#latest_major') {
        window.location.href = '{{ latest_major_url | safe }}';
    }
    {% endif %}
