Spybot 1.5.2

Well being an official spybot mirror, i get some benefits, today i opened my email to find i recieved the link for spybot 1.5.2 and i downloaded and installed it. I ran it and first thing i noticed is it looks pretty much looks the same, but has some more bot checks, and runs a bit faster than the older, or i could be wrong and its just all internal changes? The update is now on the download page!
