Google Talk: Open Communications (developers.google.com)

Can we add a year to this headline? I was excited because I thought this was new information.

From the content:

  To enable this, Google Talk uses the standard XMPP protocol for authentication, presence, and messaging.

... but don't miss the heading

  We announced a new communications product, Hangouts, in May 2013. Hangouts will replace Google Talk and does not support XMPP.
