Will ShareKit v0.2.1 stop working with Facebook soon?

Is ShareKit going to stop working for Facebook sharing come 11th October 2011? As I understand it the current version (0.2.1gm1) of ShareKit uses the REST api, which is based on the old iPhone SDK (facebook-iphone-sdk) an开发者_JS百科d according to today's blog:

On October 11th, apps using the old JavaScript Library (FeatureLoader.js) or the old iPhone SDK (facebook-iphone-sdk) for authentication will no longer be able to authenticate users until these apps switch to OAuth 2.0

Or does it already use OAuth 2.0, so no changes are needed? Just a little confused as to whether I need to update my apps in advance or not - thanks!
