Scratch 3.0 is the third and current major version of Scratch. It was released on January 2, 2019 and is a complete redesign and reimplementation of Scratch written in JavaScript.[1] It features a new, modern look and design, and fixed many bugs present in Scratch 2.0. It is compatible with many mobile devices and does not require the Flash Player, enabling users to view and edit projects from a wider range of locations.

Development

Main article: Development of Scratch 3.0

The development of Scratch 3.0 was a long process which started long before the official release.

In May 2016, the Scratch Team announced a partnership with Google to create Scratch Blocks, a library of graphical programming blocks. Later in 2016 and 2017, many changes were made to the User Interface.

On January 18, 2018, a preview of Scratch 3.0 was released at preview.scratch.mit.edu. On August 1, a beta version was released at beta.scratch.mit.edu which added new extensions, and the Scratch 3.0 Beta forum was created so Scratchers could give feedback. During the beta, many major bugs in the editor were fixed.

Interface

Main article: User Interface
The different areas of the User Interface.

The Scratch editor is designed to make coding easier for beginners and New Scratchers. The area for editing the project is on the left, while the Stage (for viewing projects) and the Sprites Pane are on the right.

Organization

Scratch is organized into multiple sprites, which act as multiple characters that can interact with each other using blocks. The Sprites can be accessed using the Sprites Pane in the bottom right under the Stage. Each sprite has its own blocks, costumes, and sounds, and can move on its own.

Code Area

Main article: Code Area

The Code Area is located on the left of the editor. where one adds and edits blocks, which are bits of code that act as scripts that run the project. To the left is the Block Palette, the area from which blocks can be dragged. Blocks are grouped into 9 sections: Motion, Looks, Sound, Events, Control, Sensing, Operators, Variables, and My Blocks. There are also multiple extensions that can be added to the project. The extensions have extra features or let Scratch interact with external devices.

Paint Editor

In early-mid January 2019, the front page banner was changed from "The new Scratch is here!" to "Create stories, games, and animations" and "Share with others around the world". Below the banner, there are two buttons: "Start Creating", leading to the project editor, and "Join", leading to a page to create a Scratch account. There was also a video demonstrating what you can create with Scratch.

File Formats

Main article: Scratch File Format

Scratch 3.0 uses .sb3 file format for projects and .sprite3 for sprites. These formats are more efficient than Scratch 2.0 file formats.[citation needed]

Controversy

Scratch 3.0 was criticized for its lack of new features and changes to the user interface. Some users quit Scratch because they were dissatisfied with the new design and/or did not like the changes made to Scratch.[5]
