Tighten up some vertical whitespace on reference landing page
Use the constant (if present, otherwise a hacky hardcoded 3.9) to request a specific version in the 'New in' widget on reference landing page since the latest WP version can't be reliably ascertained purely from the @since taxonomy.
Add 'WordPress' to the 'New in' reference landing page widget
Add 'Methods' to the list of section on the reference landing page
Redirect home landing page requests to code reference until other sections become live and thus justifying a main landing page
