Release Notes: This release fixes segfaults that occurred when using the -k option with MP3s that had an incomplete set of ID3 tags, and now falls back on other devices (such as from the sound card to esound) if the default device can't be opened.
Release Notes: Mono output function re-added.
Release Notes: WAV file output has been fixed.
Release Notes: As of this version, mpg321 should now function fully as a Free drop-in replacement for mpg123. Signal handling and getopt option handling have been implemented in order to make mpg321 act more like mpg123. mpg321 now depends on the newest version of libao (0.6.0, available from xiphophorous CVS) and smpeg (1.1.8, required because of devfs fixes). This version should function properly for everyone in every situation; if it doesn't, it's a bug.
