1383                                         <li>Fixed a minor bug in <span class="commandname">libFLAC</span> where multiple calls to setting the file name on a file decoder caused leaked memory.</li>
1384                                         <li>Fixed a minor bug in <span class="commandname">metaflac</span>, now correctly skips an id3v2 tag if present.</li>

1397                                 It's finally here.  There are a few new features but mostly it is minor bug fixes since 0.10:
1398                                 <ul>
1399                                         <li>New '--sector-align' option to <span class="commandname">flac</span> which aligns a group of encoded files on CD audio sector boundaries.</li>
1400                                         <li>New '--output-prefix' option to <span class="commandname">flac</span> to allow the user to prepend a prefix to all output filenames (useful, for example, for encoding/decoding to a different directory).</li>
1401                                         <li>Better WAVE autodetection (doesn't rely on ungetc() anymore).</li>
1402                                         <li>Cleaner one-line encoding/decoding stats.</li>
1403                                         <li>Changes to the libFLAC interface and type names to make binary compatibility easier to maintain in the future.</li>
1404                                         <li>New '--sse-os' option to 'configure' to enable faster SSE-based routines.</li>
1405                                         <li>Another (hopefully last) fix to the Winamp 2 plugin.</li>
1406                                         <li>Slightly improved Rice parameter estimation.</li>
1407                                         <li>Bug fixes for some very rare corner cases when encoding.</li>

1416                 <ul>
1417                         <li>
1418                                 This is probably the final beta.  There have been many improvements in the last two months:
1419                                 <ul>
1420                                         <li>Both the encoder and decoder have been significantly sped up.  Aside from C improvements, the code base now has an assembly infrastructure that allows assembly routines for different architectures to be easily integrated.  Many key routines have now have faster IA-32 implementations (thanks to Miroslav).</li>
1421                                         <li>A new metadata block <a href="format.html#def_SEEKTABLE">SEEKTABLE</a> has been defined to hold an arbitrary number of seek points, which speeds up seeking within a stream.</li>
1422                                         <li><span class="commandname">flac</span> now has a command-line usage similar to 'gzip'; make sure to see the latest <a href="documentation.html">documentation</a> for the new usage.  It also attempts to preserve the input file's timestamp and permissions.</li>
1423                                         <li>The -# options in <span class="commandname">flac</span> have been tweaked to yield the best compression-to-encode-time ratios.  The new default is -5.</li>
1424                                         <li><span class="commandname">flac</span> can now usually autodetect WAVE files when encoding so that -fw is usually not needed when encoding from stdin.</li>
1425                                         <li>The WAVE reader in <span class="commandname">flac</span> now just ignores (with a warning) unsupported sub-chunks instead of aborting with an error.</li>
1426                                         <li>Added an option '--delete-input-file' to <span class="commandname">flac</span> which automatically deletes the input after a successful encode/decode.</li>
1427                                         <li>Added an option '-o' to <span class="commandname">flac</span> to force the output file name (the old usage of "flac - outputfilename" is no longer supported).</li>
1428                                         <li>Changed the XMMS plugin to send smaller chunks of samples (now 512) so that visualization is not slow.</li>
1429                                         <li>Fixed a bug in the stream decoder where the decoded samples counter got corrupted after a seek.</li>

1441                                 Bug fixes and some new features:
1442                                 <ul>
1443                                         <li>FLAC's sync code has been lengthened to 14 bits from 9 bits.  This should enable a faster and more robust synchronization mechanism.</li>
1444                                         <li>Two reserved bits were added to the frame header.</li>
1445                                         <li>A CRC-16 was added to the FLAC frame footer, and the decoder now does frame integrity checking based on the CRC.</li>
1446                                         <li>The format now includes a new subframe field to indicate when a subblock has one or more 0 LSBs for all samples.  This increases compression on some kinds of data.</li>
1447                                         <li>Added two options to the analysis mode, one for including the residual signal in the analysis file, and one for generating gnuplot files of each subframe's residual distribution with some statistics.  See the latest <a href="documentation.html#analysis_options">documentation</a>.</li>
1448                                         <li>XMMS plugin now supports 8-bit files.</li>
1449                                         <li>Fixed a bug in the Winamp2 plugin where the audio sounded garbled.</li>
1450                                         <li>Fixed a bug in the Winamp2 plugin where Winamp would hang sporadically at the end of a track (c.f. <a href="http://sourceforge.net/projects/flac/&amp;atid=113478">bug #231197</a>).</li>

1463                                 Changes since 0.7:
1464                                 <ul>
1465                                         <li>Created a new utility called <span class="commandname">metaflac</span>.  It is a metadata editor for .flac files.  Right now it just lists the contents of the metadata blocks but eventually it will allow update/insertion/deletion.</li>
1466                                         <li>Added two new metadata blocks: PADDING which has an obvious function, and APPLICATION, which is meant to be open to third party applications.  See the <a href="format.html#def_APPLICATION">latest format docs</a> for more info, or the new <a href="id.html">id registration page</a>.</li>
1467                                         <li>Added a <span class="argument">-P</span> option to <span class="commandname">flac</span> to reserve a PADDING block when encoding.</li>
1468                                         <li>Added support for 24-bit files to <span class="commandname">flac</span> (the FLAC format always supported it).</li>
1469                                         <li>Started the Winamp3 plugin.</li>
1470                                         <li>Greatly expanded the test suite, adding more streams (24-bit streams, noise streams, non-audio streams, more patterns) and more option combinations to the encoder.  The test suite runs about 30 streams and over 5000 encodings now.</li>
1471                                         <li>Fixed a bug in <span class="commandname">libFLAC</span> that happened when using an exhaustive LPC coefficient quantization search with 8 bps input.</li>
1472                                         <li>Fixed a bug in <span class="commandname">libFLAC</span> where the error estimation in the fixed predictor could overflow.</li>
1473                                         <li>Fixed a bug in <span class="commandname">libFLAC</span> where LPC was attempted even when the autocorrelation coefficients implied it wouldn't help.</li>
1474                                         <li>Reworked the LPC coefficient quantizer, which also fixed another bug that might occur in rare cases.</li>
1475                                         <li>Really fixed the '-V overflow' bug (c.f. <a href="http://sourceforge.net/p/flac/bugs/5/">bug #231976</a>).</li>
1476                                         <li>Fixed a bug in <span class="commandname">flac</span> related to the decode buffer sizing.</li>
1477                                 </ul>
1478                                 FLAC is very close to being ready for an official release.  The only known problems left are with the Winamp plugins, which should be fixed soon, and pipes with MSVC.

1507                                 The encoder is now much faster.  The -m option has been sped up by 4x and -r improved, meaning that in the default compression mode (-6), encoding should be at least 3 times faster.  Other changes:
1508                                 <ul>
1509                                         <li>Some bugs related to <span class="commandname">flac</span> and pipes were fixed</li>
1510                                         <li>A "loose mid-side" (<span class="argument">-M</span>) option to the encoder has been added, which adaptively switches between independent and mid-side coding, instead of the exhaustive search that <span class="argument">-m</span> does.</li>
1511                                         <li>An analyze mode (<span class="argument">-a</span>) has been added to <span class="commandname">flac</span>.  This is useful mainly for developers; currently it will dump info about each frame and subframe to a file.  It's a text file in a format that can be easily processed by scripts; a separate analysis program is in the works.</li>
1512                                         <li>The source now has an autoconf/libtool-based build system.  This should allow the source to build "out-of-the-box" on many more platforms.</li>

1523                                 This is the first beta version of FLAC.  Being beta, there will be no changes to the format that will break older streams, unless a serious bug involving the format is found.  What this means is that, barring such a bug, streams created with 0.5 will be decodable by future versions.  This version also includes some new features:
1524                                 <ul>

1526                                         <li>A test mode (<span class="argument">-t</span>) has been added to <span class="commandname">flac</span>.  It works like decode mode but doesn't write an output file.</li>
