The main change was to make FFE as ezpz as any other ladder map.
The new setup has a 2 square backdoor that can be blocked with a pylon/depot, and then a 7 square front choke. Easy FFE, but still with plenty of potential for your natural to get busted, or for you to open up your natural should you choose.
There are a lot of other changes, such as the improvement of the middle (very free movement through those mineral lines, even for large units, which could be important) and some aesthetic additions.
You can play it if you're bored - published on all regions as "New Veridian".
