Among other improvements, the OS X version has aa Java 8 runtime inside, enables echo cancelling by default, and uses the CoreAudio subsystem. The Linux build fixes font issues with the GTK+ native LookAndFeel, and fixes someissues about microphone volume level on call starting when using the PulseAudio sound system.
