require('react/addons') is deprecated

Receiving the following warning in the Chrome dev console:
Warning: require('react/addons') is deprecated. Access using require('react-addons-{addon}') instead.

Same problem; I end up using npm package 'react-addons-linked-state-mixin' and
import LinkedStateMixin from 'react-addons-linked-state-mixin';
and then
reactMixin(LoginView.prototype, LinkedStateMixin);

Did that fix the problem? If not, what can I do to fix this? It's making my OCD twitch.
