Josh Coalson6b21f662006-09-13 01:42:27 +0000[diff] [blame]56 This is an informal changelog, a summary of changes in each release. Particulary important for developers is the precise description of changes to the library interfaces. See also the <a href="http://flac.sourceforge.net/api/group__porting.html">porting guide</a> for specific instructions on porting to newer versions of FLAC.

Josh Coalson6d8ce242006-10-07 01:19:20 +0000[diff] [blame]68 <li>Improved compression with no impact on format or decoding speed.</li>
Josh Coalson1a8afc72006-07-06 07:49:07 +0000[diff] [blame]69 <li>Much better recovery for corrupted files</li>
Josh Coalsonb51392b2006-10-06 05:51:13 +0000[diff] [blame]70 <li>Better multichannel support</li>
Josh Coalson6d8ce242006-10-07 01:19:20 +0000[diff] [blame]71 <li>Large file (&gt;2GB) support everywhere</li>
Josh Coalsonbfda3782006-08-28 03:42:10 +0000[diff] [blame]72 <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>
Josh Coalsonaec8bb32006-11-02 04:06:56 +0000[diff] [blame]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>
Josh Coalsonb292e752006-09-14 00:40:03 +0000[diff] [blame]74 <li>Support for new <tt>REPLAYGAIN_REFERENCE_LOUDNESS</tt> tag.</li>
Josh Coalson8da98c82006-10-15 04:24:05 +0000[diff] [blame]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>

Josh Coalsonaec8bb32006-11-02 04:06:56 +0000[diff] [blame]81 <li>New <span class="code"><a href="format.html#def_PICTURE">PICTURE</a></span> metadata block for storing things like cover art.</li>
Josh Coalsond0edb972006-10-07 06:50:08 +0000[diff] [blame]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>

Josh Coalsonbfda3782006-08-28 03:42:10 +0000[diff] [blame]96 <li>Encoder can now take 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>
Josh Coalsonb51392b2006-10-06 05:51:13 +0000[diff] [blame]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>
Josh Coalson6d8ce242006-10-07 01:19:20 +0000[diff] [blame]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>
Josh Coalsonaec8bb32006-11-02 04:06:56 +0000[diff] [blame]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>

Josh Coalsoncee66cf2005-08-24 00:32:40 +0000[diff] [blame]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>
Josh Coalson7688f8e2006-07-07 01:05:33 +0000[diff] [blame]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>

Josh Coalson0d903aa2005-08-09 00:59:39 +0000[diff] [blame]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>
Josh Coalson7fdd6882005-09-03 01:33:12 +0000[diff] [blame]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>

189 <li><b>Changed</b> FLAC__StreamDecoderErrorStatus: new error code FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM</li>
190 <li>The above two changes mean that when the decoder encounters what it thinks are unparseable frames from a future decoder, instead of returning a fatal error with the FLAC__STREAM_DECODER_UNPARSEABLE_STREAM state, it just calls the error callback with FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM and leaves the behavior up to the application.</li>

275 <li>libFLAC: Sped up Rice block decoding in the bitbuffer, resulting in decoding speed gains of a few percent.</li>
276 <li>libFLAC: Sped up encoding when not using LPC (i.e. <span class="code">max_lpc_order == 0</span>).</li>
277 <li>libFLAC: Trailing NUL characters maintained on Vorbis comment entries so they can be treated like C strings.</li>
278 <li>libFLAC: More FLAC tag (i.e. Vorbis comment) validation.</li>
279 <li>libFLAC: Fixed a bug in the logic that determines the frame or sample number in a frame header; the bug could cause sync errors with some ID3v1-tagged FLAC files.</li>
280 <li>libFLAC, libOggFLAC: Can now be compiled to use only integer instructions, including encoding. The decoder is almost completely integer anyway but there were a couple places that needed a fixed-point replacement. There is no fixed-point version of LPC analysis yet, so if libFLAC is compiled integer-only, the encoder will behave as if the max LPC order is 0 (i.e. used fixed predictors only). LPC decoding is supported in all cases as it always was integer-only.</li>

370 <li>When encoding multiple Ogg FLAC streams, <span class="argument">--serial-number</span> or random serial number sets the first number, which is then incremented for subsequent streams (before, the same serial number was used for all streams).</li>
