Enhancements to the Google+ JavaScript SDK

In store for developers making use of the Google+ Sign-In API are javascript SDK enhancements, improving functionality and more.

Let's take a look at the changelog for the release:
  • gapi.auth.signIn() triggers user sign-in and authorization in JavaScript, making it easier to integrate Google+ Sign-In with existing account creation flows. 
  • gapi.auth.signOut() signs the current user out of your app. 
  • A new status field indicates whether users are signed in to Google and/or your website, and a new method field describes how the sign-in occurred. 
  • You can now specify sign-in parameters once in <meta> tags, versus passing them multiple times to multiple page elements. These page-level configuration parameters simplify your integration of Google+ Sign-In and interactive posts. 
  • The sign-in callback is now dynamic when using page-level configuration. This makes it possible, for example, to sync your site’s user experience across multiple tabs. 
To boil it all down into simpler terms, Google is making it even easier to integrate Google+ Sign-In on websites. For users, there is now an easier way to sign out of an integrated website.

The updates announced today are fully backwards compatible with current integrations of Sign In, so there's no tweaking needed to have the latest changes.

How likely are you to implement the Sign-In system on your site? What features do you hope they're working on behind the scenes?
