According to 2K community manager Greg Laab, the patch notes--originally made available yesterday--do not represent the entire upcoming update. Based on feedback in the forums following the partial patch details, it appears that the most favored change is the ability to disable "auto-unit cycling."

Although a small issue in early games, auto-unit cycling makes playing Civilization V a nightmare at every turn in late game stages, snapping the camera to every available unit in seemingly no organized order. We couldn't be happier that, soon, that issue will come to a timely end.

User Interface
• Fix for production prompt that sometimes appears with newly created puppet states that could stop the player from being able to end the turn.
• Aircraft banner corrections - now when you rebase an aircraft, the number will move with it.
• Resource icons now come up with Ctrl-R again, instead of sharing the same button with Build Roads.
• Selecting a great general will no longer cause yield icons to appear.
• Added option to disable auto-unit cycling.
• Fix for full-screen game when running dual monitors. Previously, the curser could scroll off the "open" side, and not be able to scroll the map in that direction.
• Misc additional fixes to mouse controls, and other interface issues.
• Rounded out financial information in the Economic Overview screen. Details now provided on the amount of gold provided by each city, the cost of buildings in each city, etc.
• Auto-populate save menu with save file name
• Allow selection of other cities by hex from within the city screen
• Added detailed trade route info to Economic Overview screen
