Regarding the GAE SDK update, the production environment is automatically updated by Google. That is, whenever a new version is released, the production version will be updated to this new version. Therefore, you do not need to worry about the version working in a production environment.
As for the local test environment, a manual task is required to upgrade the version. Since @splix asked which language you use, the process may be slightly different. In my case, as a Java developer, we are using the Maven plugin here to handle all of this. So essentially, you need to update pom.xml to point to the correct version of GAE, and run mvn gae: unpack, the entire latest version will be downloaded and used by your local environment.
This process is also very convenient in the Eclipse plugin, since basically you need to update the Google plugin for Eclipse as what you did to install it. And after that, the local environment will pick up the latest version that she received.
I am not a guy in Python, so if you are after Python, my answer above will not help me. Sorry.
