What should I use instead of DS.FixtureAdapter

You gotta love ember.js team... I'm getting this depreciation message saying that: "DS.FixtureAdapter has been deprecated and moved into an unsupported addon: http://ift.tt/1e9rbDC". Guys maintaining that addon advise that we should use a library similar to Pretender. Has anybody done that? Is there a tutorial showing how to integrate this lib so that everything would work as before?
