It looks like the second player to found in a 1v1 instantly gets to found with no debt now (and also no possibility of extra bonus money)? Beyond that odd quirk, I couldn't really get a read on any of the changes from today's 1v1 daily.
There was a weird moment in my replay, around the start of day 3, where the AI throws an EMP at empty space, though.
EDIT: Also wanted to mention that hotkeys for choosing HQ types during the founding phase no longer work. A silhouette in the shape of the HQ type will flash briefly, but you can't actually found when clicking during that time.
