64                 <ul>
65                         <li>
66                                 General:
67                                 <ul>
68                                         <li>Improved compression with no impact on format or decoding speed.</li>
69                                         <li>Much better recovery for corrupted files</li>
70                                         <li>Better multichannel support</li>
71                                         <li>Large file (&gt;2GB) support everywhere</li>
72                                         <li><span class="commandname">flac</span> now supports FLAC and Ogg FLAC as input to the encoder (i.e. can re-encode FLAC to FLAC) and preserve all the metadata like tags, etc.</li>
73                                         <li>New <span class="code"><a href="format.html#def_PICTURE">PICTURE</a></span> metadata block for storing things like cover art, new <span class="argument"><a href="documentation.html#flac_options_picture">--picture</a></span> option to <span class="commandname">flac</span> and <span class="argument"><a href="documentation.html#metaflac_shorthand_import_picture_from">--import-picture-from</a></span> option to <span class="commandname">metaflac</span> for importing pictures, new <span class="argument"><a href="documentation.html#metaflac_shorthand_export_picture_to">--export-picture-to</a></span> option to <span class="commandname">metaflac</span> for exporting pictures, and metadata API <a href="api/group__flac__metadata__level0.html#ga3">additions</a> for searching for suitable pictures based on type, size and color constraints.</li>
74                                         <li>Support for new <tt>REPLAYGAIN_REFERENCE_LOUDNESS</tt> tag.</li>
75                                         <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>
76                                 </ul>
77                         </li>
78                         <li>
79                                 FLAC format:
80                                 <ul>
81                                         <li>New <span class="code"><a href="format.html#def_PICTURE">PICTURE</a></span> metadata block for storing things like cover art.</li>
82                                         <li>Speaker assignments and channel orders for 3-6 channels (see <a href="format.html#frame_header">frame header</a>).</li>
83                                         <li>Further restrictions on the <a href="format.html#subset">FLAC subset</a> when the sample rate is &lt;=48kHz; in this case the maximum LPC order is now 12 and maximum blocksize is 4608.  This is to further limit the processing and memory requirements for hardware implementations while not measurably affecting compression.</li>
84                                 </ul>
85                         </li>
86                         <li>
87                                 Ogg FLAC format:

93                                 flac:
94                                 <ul>
95                                         <li>Improved the <span class="argument"><a href="documentation.html#flac_options_decode_through_errors">-F</a></span> option to allow decoding of FLAC files whose metadata is corrupted, and other kinds of severe corruption.</li>
96                                         <li>Encoder can now take FLAC and Ogg FLAC as input.  The output FLAC file will have all the same metadata as the original unless overridden with options on the command line.</li>
97                                         <li>Encoder can now take WAVEFORMATEXTENSIBLE WAVE files as input; decoder will output WAVEFORMATEXTENSIBLE WAVE files when necessary to conform to the latest Microsoft specifications.</li>
98                                         <li>Now properly supports AIFF and WAVEFORMATEXTENSIBLE multichannel input, performing necessary channel reordering both for encoding and decoding.  WAVEFORMATEXTENSIBLE channel mask is also saved to a tag on encoding and restored on decoding for situations when there is no natural mapping to FLAC channel assignments.</li>
99                                         <li>Expanded support for "odd" sample resolutions to WAVE and AIFF input; all resolutions from 4 to 24 bits-per-sample now supported for all input types.</li>
100                                         <li>Added a new option <span class="argument"><a href="documentation.html#flac_options_tag_from_file">--tag-from-file</a></span> for setting a tag from file (e.g. for importing a cuesheet as a tag).</li>

102                                         <li>Added a new option <span class="argument"><a href="documentation.html#flac_options_apodization">--apodization</a></span> for specifying the window function(s) to be used in LPC analysis.</li>
103                                         <li>Added support for encoding from non-compressed AIFF-C (<a href="https://sourceforge.net/tracker/?func=detail&amp;atid=113478&amp;aid=1090933&amp;group_id=13478">SF #1090933</a>).</li>
104                                         <li>Importing of non-CDDA-compliant cuesheets now only issues a warning, not an error (see <a href="http://www.hydrogenaudio.org/forums/index.php?showtopic=31282">here</a>).</li>
105                                         <li>MD5 comparison failures on decoding are now an error instead of a warning and will also return a non-zero exit code (<a href="https://sourceforge.net/tracker/index.php?func=detail&amp;aid=1493725&amp;group_id=13478&amp;atid=113478">SF #1493725</a>).</li>
106                                         <li>The default padding size is now 8K, or 64K if the input audio stream is more than 20 minutes long.</li>
107                                         <li>Fixed a bug in cuesheet parsing where it would return an error if the last line of the cuesheet did not end with a newline.</li>
108                                         <li>Fixed a bug that caused a crash when <span class="argument">-a</span> and <span class="argument">-t</span> were used together (<a href="https://sourceforge.net/tracker/index.php?func=detail&amp;aid=1229481&amp;group_id=13478&amp;atid=113478">SF #1229481</a>).</li>
109                                         <li>Fixed a bug with --sector-align where appended samples were not always totally silent (<a href="https://sourceforge.net/tracker/index.php?func=detail&amp;aid=1237707&amp;group_id=13478&amp;atid=113478">SF #1237707</a>).</li>
110                                         <li>Fixed bugs with --sector-align and raw input files.</li>
111                                         <li>Fixed a bug printing out unknown AIFF subchunk names (<a href="https://sourceforge.net/tracker/index.php?func=detail&amp;aid=1267476&amp;group_id=13478&amp;atid=113478">SF #1267476</a>).</li>
