App Engine 1.5.3 SDK Released

We’re pleased to announce another App Engine release today. You might have noticed that the rate of releases has gone up slightly in the past few months. We’ve made some changes internally so we are looking to push out a new release every month. This month includes a few Datastore updates, some changes to Blobstore API and Memcache API, and finally a new feature for Java developers.

Python and Java Changes
  • Blobstore API - We’ve removed the limits on the size of blob uploads. You can now upload files of any size, allowing your app to serve images, video, or anything your internet connection can handle.
Datastore Changes
  • Index retrieval - We’ve added the ability for you to programmatically retrieve the list of indexes you’ve currently defined in the datastore, as well as their statuses.
  • Datastore Admin - You can now enable the Datastore Admin function from the Admin Console. This will allow Java users to make use of this functionality, like deleting all entities of a certain kind, without having to upload a Python version of their application. And for Python developers, you no longer need to enable this in your app.yaml file.
  • HRD Migration Trusted Testers - We are seeking early adopters to try out an improved HRD migration tool that requires a read-only period relative to your datastore write rate (as opposed to your datastore size, which is how the current version behaves). Please see the release notes for more information.
Python Updates
  • Memcache API - We now support the CAS (compare-and-swap) operation in our Python Memcache API (Java already had it). This can be used to update a value in Memcache only if no other requests have updated it between when the value was retrieved and when you go to update it.
Java Updates
    • Download app - Using the AppCfg download_app command, you can download any files that were uploaded from your war directory when you last updated the app version.
    This release also contains small updates and bugfixes for both Python and Java so be sure to check out the full release notes. Feedback, discussion, and questions can be posted in our Google Group.

    Could you please change app engine luncher on windows so that I don't have to click OK with each new release? Printing a log message is still ok, but I don't want to click ok or download App Engine SDK each month. Thanks!

    Hi there. I'm really pleased with all the cool features the new release brings. I'm still looking to see some enhancements regarding the limit in the number of static files to be uploaded. You see, I'm using SmartGWT in my application and trying to use the frogtree skin, which increases my application static files to 3450 and makes my deploy to be rejected. The solutions presented as using a zip file is too slow and doesn't work very well, and hiring S3 to keep the static files requires a little budget, what is not a good thing until I start making some money out of my application. Is it really too bad to increase the limit in 2 or 3 thousand static files?

    The Blobstore API limits could be sort of "bottleneck" for our backup tool http://www.datastorebackup.com

    .. these are good news! Thanks!
