Google App Engine 1.7.5 released today with High-Memory Instances and Mail Bounce Notifications to General Availability.
"With this release, you can now utilize F4 or B4 instances with 1GB memory, which is double the amount of memory available before. Mail Bounce Notifications notify apps when mail sent through App Engine fails to deliver, so you'll always know whether your communications are going through," Google wrote.
Additionally, Goole also introduces experimental support for the Java 7 runtime and Google Cloud Endpoints.
"Improvements in Java 7 include strings in switch statements, improved type inference for generic instance creation, and the ability to use InvokeDynamic()," while "Cloud Endpoints makes it easy to expose your code as RESTful and RPC services that can be easily consumed by your own web and mobile applications," explains Google.
Finally, Google Plugin for Eclipse also update today to make it possible for developers to build App Engine backends that communicate with client-side Android applications via Google Cloud Messaging for Android and Cloud Endpoints.
