What is the most recent version of GAE SDK that supports Python 2.5?

Question

We're in the process of migrating an app from python 2.5 to python 2.7.

The latest SDK (1.8.3) does not support python 2.5.

What is the most recent version of the SDK that does support python 2.5? Please link to source if you have it.

Answer 1

From the SDK Release Notes, it appears that at the very least 1.6.2 supports Python 2.5, while the most recent version to mention Python 2.5 is 1.8.2.

There is no mention anywhere in the release notes that GAE no longer works with 2.5, but instead that is deprecated and new apps for 2.5 will be no longer allowed. If you look at the table of differences for GAE, it certainly shows you can use 2.5, just not everything is supported.

Just be sure your app.yaml uses:

runtime: python

Rather than python27, and you should be Ok.
