GAE 1.4.0 Released

App Engine 1.4.0 Gets Pre-Emptive

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.
