The release notes are pretty brief as usual and probably don’t describe half of what changed. Please, please, please give me an option to turn of the fucking URL completion (unless there is one and it’s tucked away somewhere inconspicuous).
They fixed the egregious problems with URL completion in 3.0–now Safari only autocompletes the host portion of the URL. I haven’t had cause any problems since then.
Or do you object to a list of autocomplete options showing up at all?
