A relatively small thing all in all, but in the big update, lists no longer allow you to use special characters in the name. We often use dates in our list names which now have to be formatted strangely.
Also when you go to add existing contacts to a list and click "select all contacts" it still only adds the contacts on that page and not all. You are able to get around this by going to the "Contacts" page and adding them to the list from there, but would be cool if this worked as (I'm assuming) intended.
