Yes, was it "this version" that made it better than MP3? I'd have thought the title would say what was new. Guess not...

Opus has always been better than MP3. Another big benefit of Opus over AAC and MP3 is that Opus is royalty-free for all uses whereas AAC and MP3 require the payment of patent licensing fees.

The last of the US patents covering MP3 should expire next year.
