Yes fixes were included in that patch but I'm talking about the 2 gig download, not the multiple smaller ones in between. There was one large download and install at some point prior to the exp. As fixing exploits and making minor updates is mostly appending code, there's no way that 2 gig file was all code just for that. There had to have been other content like new 3d models and a ton more code. It's up to you what you choose to believe, but my experience tells me they added a lot of new content at some point.
