The New Ports page is not sorting by date. I guess you haven’t noticed. Well, it is sorting by date, but alphabetically, not chronologically. Have a look at the above URL, then compare it with what I have done in my develoment site.
You’ll see that the first sorts alphabetically, the second actually gets the date in the right order.
On a side note, both pages need to be cached to improve speed.
This fix is now in production. :)
