New bi-directional channel for latest GAE release.

Google App Engine version 1.4.0 has been released. This release adds a bi-directional channel for communicating with the user’s browser by pushing notifications directly to the JavaScript running on the client, and adds an Always On feature for reserving instances, which targets applications with low or variable traffic. Please note that Always On is a premium feature, with a price tag of $9 per month, which reserves three instances on your applications. There is also a ‘Warm Up Requests’ feature which anticipates the need for more instances and loads them before user traffic is sent to the new instance, in an effort to reduce the time required to serve requests.
