<li>Better multichannel support</li>
<li>Large file (>2GB) support everywhere</li>
<li><span class="commandname">flac</span> now supports FLAC as input to the encoder (i.e. can re-encode FLAC to FLAC) and preserve all the metadata like tags, etc.</li>

<li>Support for new <tt>REPLAYGAIN_REFERENCE_LOUDNESS</tt> tag.</li>
<li>In the developer libraries, the interface has been simplfied by merging the three decoding layers into a single class; ditto for the encoders. Also, libOggFLAC has been merged into libFLAC and libOggFLAC++ has been merged into libFLAC++ so there is a single API supporting both native FLAC and Ogg FLAC.</li>
