Hello App Engine Developers, As part of our ongoing efforts to improve release quality and transparency, we will start prereleasing SDKs for early testing. We hope this gives developers a chance to participate in our release process by trying out new changes and sending feedback. As of this morning, the prerelease SDK for our next release, 1.2.8, is available in the familiar download location (note that the filename ends in 'prerelease.zip'):
http://code.google.com/p/googleappengine/downloads/list If you're interested, please download and give it a try locally with your favorite App Engine code. Please note that, as a prerelease, this SDK is not yet supported and still subject to change. Thus, please don't take critical dependencies or make substantial changes to production apps based on this SDK. Importantly, this prerelease is purely for the SDK and is intended for local testing and development in dev_appserver. The server-side of App Engine (our production environment) is not at 1.2.8, so deploying with this SDK is not yet supported. In the future, we might enable a complete SDK and server test environment for prereleases. A few notes on 1.2.8 in particular - this release is primarily for servicing and updates in preparation for some exciting feature launches we have in the pipeline. The current release notes (still subject to change) are included below; these release notes do include changes which will only be available on the server side Admin Console (non-local) once 1.2.8 is formally released. Please try 1.2.8 for local development and send us your feedback! Thanks, App Engine Team Version 1.2.8 ============= - Support for JAXB. JAXB is included in JDK 1.6 (and App Engine's production servers). If you're using JDK 1.5 with your local dev_appserver, you will need to include the JAXB libraries with your application to use it. http://code.google.com/p/googleappengine/issues/detail?id=1267 - Added Quota API (com.google.appengine.api.quota) to match Python API. - Low-level Memcache API now supports grabTail() and batchIncrement (). - HTTPResponse object now has getFinalUrl() method for 302 redirects. http://code.google.com/p/googleappengine/issues/detail?id=1464 - Java Dev Appserver now automatically executes tasks.
