I'm about a day late to the game, but Google has released version 1.4.3 of their cloud-based PaaS. For those of us using OpenBD on the Google App Engine the latest enhancements to the Java platform side are particularly welcome.
- Concurrent Requests - This one is a big #winning! Instead of firing up more app instances, a single app instance can handle more requests. It does require a configuration change in your application.
- Java Remote API - This provides the ability to execute actions against your datastore remotely. Seeing that I am crafting webservices for this kind of thing right now, remote access could be a big deal. We'll see.
- Files API - About...time... Ability finally to be able to do file-like manipulation with their Blobstore. Let's hope it is as awesome as it sounds.
Although not a huge release, there are some pretty big items in there that could have dramatic effect your applications. The official release notes are here.
