     55'''Note to codec writers:''' 
     56 
     57A new mandatory '''destroy''' callback has been added to factory operation. You must implement this callback (hint: just point it to your existing function that deinitialize your codec factory). 
     58 
     59'''Note to app writers:''' 
     60 
     61You don't need to initialize each codec now, just use {{{pjmedia_codec_register_audio_codecs()}}} above. Similarly you should remove all the calls to codec deinitialization routines since that will be done automatically when the media endpoint is destroyed (leaving these calls as they are is harmless though; they will render to no-ops).
