I wouldn't say any version is safe when you're botting. If you're not being stupid though (and by stupid i mean running it 24 hours a day or not checking it at least once in a while to make sure it's not clicking continuously on something) you should be pretty safe.
Oh, and if you'll be botting a lot you should disable your "sell" tabs and not be in a guild while you're doing it. That's probably the most common way to get your account looked at.
