Hi I'd like to confirm I have this problem as well. Installed fresh on Windows 7. I set "word_wrap" to false in Preferences.sublime-settings, but all of my files always open with word wrap enabled by default. It's tripping me up a lot on my source code files (.asp and .php files, if that matters).
I like all the new features in this release so I'm not about to go downgrading anytime soon, I'd rather put up with the word wrapping for now.
