Just in time for spring, App Engine 1.4.3. Release is now available and bring the Java and Python runtimes even closer to parity. “For Python, we’ve launched a test library to match the existing Java testing framework, and for Java we’ve introduced the Deferred and Remote APIs,” Google notes.
This release also introduces a new Blobstore writing feature, the experimental release of the Prospective Search API in Python, and a few goodies for Task Queue and Cron users.
Also, made a pre-announcement about the 1.4.4 release. “When 1.4.4 is released, we plan on including a change that allows both the person who uploaded the code to download it, as well as the Owner(s) of the project (as listed in the Admin Console). In preparation for this, be sure to properly assign roles to all developers on your App Engine application in the Admin Console. Alternatively, you’ll still be able to permanently disable the code download feature for your app,” Google said.
