|Hello from Google!|
You are the administrator for one or more Google App Engine applications that may be impacted by an upcoming new product release. Google will be releasing a new communications product called Hangouts which users may choose to use instead of Google Talk. The new service does not support XMPP.
As a result XMPP bots such as the App Engine XMPP service will not be able to communicate with users who adopt the new service. There are two ways to keep your App Engine XMPP service working for end users:
1) Your users may use any chat client that supports XMPP. XMPP clients will continue to work as usual with the App Engine XMPP service.
2) End users will be asked to opt-into the new service when it goes live. Note that the go-live date may vary for Google Apps domains. End users and google app domain administrators may choose not to opt into the new system. If they do not opt in they will remain on the current Talk client and there will be no change to their existing functionality, including being able to exchange messages with App Engine XMPP bots. Users who already opted in may toggle back to the old XMPP based chat clients in Gmail.
Note that the changes discussed above have no impact on non-Google XMPP clients, which will continue to work as usual with the App Engine XMPP service.
If you have any questions, comments, or concerns, please don't hesitate to email us at firstname.lastname@example.org.
