it could play regular atrac3 and stereo atrac3+ for a long while, the text just mentions it can now play the files using more functions, so more games that were completely silent before should be able to partially play sound now.
you're thinking of mono atrac3+, which can't be decoded yet. hykem supposedly had some good progress in decoding the encryption for at3+ files (so they could be implemented into the emulator without the need for sonicstage, and play both stereo and mono at3+ files), but he disappeared few months ago again.
