Today we are excited to announce the release of version 1.3.2 of the App Engine SDK for both the Java and Python runtimes. 1.3.2 includes a number of changes and bug fixes.

For this release, we have concentrated on removing a number of limitations that have been affecting developers:

• Blobstore API - A new method (fetch_data for Python, fetchData for Java) allows your application to request the contents of a Blob from within your application’s code.
• URLFetch API - We’ve expanded the number of ports you can access with the URLFetch API. You can now access ports 80-90, 440-450, and 1024-65535.
• Mail API - We’ve expanded the allowed mail attachments to include common document extensions including .doc, .ppt, and .xls.
• Task Queue API - We’ve increased the maximum total Task Queue refill rate to 50 per second.

We’re also happy to announce, based on your feedback, a new Denial of Service (DoS) blocking system in App Engine. This system allows you to blacklist specific IP addresses from accessing your application, and to prevent them from costing your application money or eating up your quota. You can also view the top IPs that have accessed your application in the Admin Console, to help you figure out what IPs you may want to block. More information on this feature is available for Python and Java.

There’s a lot of other changes and fixes in this release, including a new Java version of the Appstats profiling tool, so read the release notes (Python, Java) for a complete list of changes and download the new versions of the SDK.
