Will release this change under the 2.6.0 namespace because this may be a minor change for our users(not sure) I've checked our apps, and we use it like this

import { useFind, useSubscribe, useTracker } from 'meteor/react-meteor-data';

but people maybe using useTracker and withTracker as default exports. What do you think @radekmie ?

Published under the 2.6.0 namespace

It is a breaking change, but I don't think that anyone imported it as meteor/react-meteor-data/useTracker anyway.
