<li>Large file (&gt;2GB) support everywhere</li>
<li>Much better recovery for corrupted files</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.</li>
</ul>
