• Support decoding FLAC in MP4.
• AAC decoder: now recognizes 6.1ch/7.1ch AAC channel config constants (11 and 12) defined in 14496-3:2009/Amd 4:2013
• Concatenating files with no title tag with --concat now creates empty chapter name (formerly file name was used).
• --start now accept negative value. using --start and --delay at the same time is not allowed now. These two options are the same in functionality-wise, except for the reversed sign (For trimming, you use positive value for ---start, and negative value for --delay).
• --adts and --concat doesn't allow concatenating files with varying sample format anymore.
• External dlls are now loaded in lazy way, which means that they are not loaded until needed.
• Increased buffering size for --play to avoid glitches on multi channel files.
• --native-resampler now always use dedicated AudioConverter.
• CAF: enabled 7.1ch rear AAC output.
• AAC in CAF: when chan chunk is not present, get channel layout from kuki chunk.
• Named pipe output is removed. I guess it has been rarely used anyway, but if you happen to want it, use https://github.com/nu774/namedpipe .
