As the version number suggests this is largely a feature upgrade:

>From annoucement:

    new, less "ringing" reverb engine (openembedded#380, thanks to @jjceresa)
    new, stereophonic chorus engine (openembedded#548, thanks to @jjceresa)
    support for Downloadable Sounds (DLS) files was added (openembedded#320, requires libinstpatch)
    improved integrity checking of SoundFont modulators (openembedded#467, thanks to @jjceresa)
    rendering to stdout is now possible (openembedded#553, thanks to @mawe42)
    the following Audio Drivers have been added:
        Oboe (openembedded#464, tested on Android, thanks to @atsushieno)
        OpenSLES (openembedded#464, tested on Android, thanks to @atsushieno)
