I strongly suspect they don’t update these documents every month to keep up to date with different waves. That wouldn’t even make sense for a nation-wide document like this. Most likely these docs just got updated once when COVID first became a big deal, and will be updated again whenever someone decides the pandemic has subsided enough that it doesn’t need to be in these docs.
