<li>Now has stricter index checking to detect when different FFmpeg versions were used to create an inded of the same version</li>
<li>How indexing works has been split internally so the track numbers and types are reported, this makes it possible to create an interactive GUI or ask which audio tracks are to be indexed</li>
<li>Now has stricter index checking to detect when different FFmpeg versions were used to create an index of the same version</li>
<li>Fixed an access violation occurring when unindexed or empty audio tracks in matroska files were opened</li>
<li>Less type conversion/signedness warnings</li>
<li>When audio track dumping is performed a custom callback can now be supplied to name the tracks</li>
<li>The audio track delay is now exposed in the API in the same way as video tracks</li>
<li>A big type and argument name cleanup in the API, many things have been renamed to be clearer and it should be completely C friendly now</li>
<li>Removed FFNoLog and replaced it with FFSetLogLevel and FFGetLogLevel, the default logging is now also set to quiet, the magical numbers to supply it can be found in avutil/log.h</li>
<li>Updated FFmpeg to rev X (now with pthreads and faad2 again by popular demand, updated to GCC 4.4.0 for compiling all libraries)</li>
