Previously stories used to be in a date-based structure .../match/YYYY/MM/asdfgh.html
This has been changed to .../match_news/match_info/asdfgh.html
So far in my checking all the final documents seem to be unchanged and substituting 'match_news/match_info' for the original 'match/YYYY/MM' finds the original article.
Edit: At least some .../news/YYYY/MM/qwerty.html links have turned into .../event/events/qwerty.html links. However, some stories that were not about 'events' seem to have ended up in different categories.
