Scratch 3.0

**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. It features a new, modern look and design, and fixed many bugs present in Scratch 2.0. It does not require the Flash Player, enabling users to view and edit projects from mobile devices.

## 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 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

Main article: Paint Editor

The Paint Editor is Scratch's built-in editor where costumes for sprites can be made and edited. It has vector and bitmap (raster) versions that one can easily switch between. The Costumes Library has many premade costumes that one can use in their projects.

### Sound Editor

Main article: Sound Editor

The Sound Editor is Scratch's built-in editor where sounds for sprites can be made and edited. It has several tools that can be used to edit sounds such as a sound recorder and a sound library where premade sounds can be used.

## Updates

On January 9, 2019, the Scratch Team released new updates for Scratch 3.0, fixing many bugs Scratchers had reported. This included projects getting stuck on the loading screen, and the love and favorites not showing up. This announcement was shown on the Front Page.

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.

On April 19, 2019, some more updates were released. It included the Go Direct Force & Acceleration Extension and bug fixes.

On August 1, 2019 updates to the sound editor were released. It made improvements to the sound editor, including the option to select portions of the sound, copying and pasting, and basic keyboard shortcuts to the editor.

On February 13, 2020, an update to the Paint Editor was made. It included the Costume Centering Feature. The tool allows a costume to be centered more easily.

On May 18, 2020, more updates were made to the Paint Editor. It included a feature that made it now possible to zoom out beyond the canvas and more of the Paint Editor can now be seen on different browser sizes.

On June 28, 2023, an update to the offline editor will be made. It will include the feature to change between normal blocks and color contrast blocks, and the navigation bar will change from blue to purple. They are available to test on Scratch Lab.

## 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*]

## Reception

### Negative reception

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 as well as compatibility issues with old projects. Many community members critical of the new version used the icon of "Thanos Cat", a combination of the Scratch Cat and the head of *Thanos* from the *Avengers* film franchise who eliminated half of the universe's population by snapping his fingers. This is supposedly because the upgrade caused half of the community to disappear, but information from Statistics does not reflect this.

### Positive reception

There has been much praise for 3.0. as a smaller countermovement but is also evident by the Scratch Cat's project "*Scratch 3.0 is here!*" recieving over 6000 Loves and almost 2,000 Remixes as of March 2023.
