Build Server Problems Resolved (September 27, 2013)

Google identified the problem in their infrastructure and isolated it to one data center. Although they have not resolved the problem itself, they have relocated our application to a different data center. All valid builds should now succeed.

We intend to work with Google in the following days and weeks to get a better understanding of exactly what went wrong and how we can avoid similar problems in the future, including how to get problems isolated in a more timely way.

We sincerely apologize for this outage and truly appreciate your patience.

Import Information about MIT App Inventor Release v134 (Update: May 14, 2013)

The MIT App Inventor Release v134 is now out. You will need to upgrade your copy of the MIT AICompanion shortly after the release. The old version will work, but some components, in particular the Web component, will not work properly. Approximately a week after the release the old version will stop functioning.Version 2.07 of the MIT AICompanion is now required.

If you obtained the Companion from the Google Play Store *and* selected “Allow automatically updating” then the update will happen automatically if you are on a newer version of Android. On some phones it will require a manual installation. In that case go to the Google Play Store and update to the latest version.

If you did not obtain the app from the Play Store you will have to obtain it from our download area and install it on your phone.
