This new version adds additional flexibility, and fixes several issues that users have reported, and is now the standard MIT App Inventor 2 Mac Tools Installer. Starting now, users who follow the getting started instructions for Macintosh will obtain the new version 2.3.0.
The new tools make few user-visible changes. If App Inventor is currently working for you with Macintosh, you need not install the new version. (Leave well enough alone.)
Changes for version 2.3.0:Users should always make sure they have a backup of their data before installing any new software.
As always please let us know if you find any issues or have any questions installing these new tools. By posting a message on the MIT App Inventor Forum.
Happy Inventing!
Andrew McKinney Director of Software Development, MIT App Inventor Project
