We are now running release nb137 of MIT App Inventor 2. Below is a summary of the changes since the last release. In the next few days we will update the release notes with more details.

The current Companion, version 2.20ai2zx1 or 2.21ai2zx1, is usable with this release, but you may experience problems. Please update to the latest version, 2.22ai2zx1 as soon as possible. It will be uploaded to the Play Store shortly after this release is live. If you have auto-update enabled, you will get the new version automatically. If you “side-load” the Companion (i.e., not from Google Play), you can use the links/QR Code in the “Companion Info” selection of the “Help” menu).

• Internationalization: The MIT App Inventor service can now be translated into other languages. The first language supported is Chinese, with Spanish soon to follow. We will soon document how people can contribute translations.
• Support for Tablets: In Apps that run on tablets will be able to take advantage of the increased screen size. However, in order to support tablets, we needed to remove support for very old phones, in particular those running versions of Android less than 1.6 (Donut). NOTE: This change was reverted for release nb137, it was included in nb136 which was only available for about a day.
• Twitter Component update: We have updated the Twitter Component to submit images directly to Twitter instead of using Twitpic. Twitpic will be shutting down on September 25th. Note: If you have applications in the Google Play Store that use Twitpic, you will need to re-package your application after this release to get a version that will continue to work correctly after September 25th. You will not need any additional API keys to work with photos, and you will not need to make any changes to the blocks of your app.
• Screen Scrollable: All new Screens will be non-scrollable by default.
• Fusion Tables: We have added Service Authentication to allow developers to register authentication per app, as opposed to having to manually provide access to users by registering each individual email (the old authentication mechanism is still available). A few new blocks to make it easier to retrieve data (insert and retrieve rows from a particular table) have also been added.
