<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Accessibility: Themes: Only unlink custom logo on the home page if the theme declares support for that.
To accommodate for the change, the `custom-logo` theme feature now accepts the `unlink-homepage-logo` parameter.
If and when the logo is linked on the home page, the link has the `aria-current` attribute for better accessibility.
