Unfortunately, I can't find out a whole lot about it, because all the links I have that supposedly contain this phantom information are broken. I will say this, though, the patch contains one much-needed (and requested?) improvement. Planet scanning is now a whole lot less tedious, with a larger scanning range and faster overall scanning. Now you can typically scan a planet in less than a minute and be on your way to the next one. This was one of my biggest issues with the game, if you can even call it a bit issue at all. I'm glad they fixed it! Go Bioware!
