Assassin's Creed Unity's next major update (Patch 4) has begun rolling out on Xbox One and PS4, so forget about the delay we wrote about earlier.

Detailing the new update, Ubisoft says the patch is "mainly focused on alleviated performance issues and improving the overall experience." Part of that is an improved frame rate which Ubisoft says involved replacing and updating portions of the Paris city map. Of course, there's a number of other improvements as well — all of which are detailed in the patch notes below:

Because portions of the map had to be replaced, today's title update checks in at 6.7 GB; however, since a large portion of the patch replaces existing files the net increased to the game's overall size is actually less than 6.7 GB.

Patch 4 is rolling out to Xbox One and PS4 players today and will be available on PC later in the week.
