Scratch 3.0 includes a new sound editor, new sprites, new programming blocks, and much more.

A new build

Scratch was originally built with Adobe Flash which is going away soon so the new update is built in HTML5 and a Javascript library called React.

What does that mean for us? 

Scratch can now be used on tablets and almost all hardware, like Raspberry Pi for example!

Scratch Extensions

Scratch extensions is a new feature that allows for Scratch programs to talk to external hardware and online resources. Micro:bit even has its own extension!
