To use this in the Mac, it needs to be used with a Mac to run it, and it is a C++ based program. It can also be used to create movies, look like CD covers, and it's even a very good graphics design program. And because it is a great program, one can even do some virtual demos. Offline versions of Scratch 1.4 and 2.0 are still available.There are so many different versions of Unity available. Scratch remains free to use and version 3 is available in both a web version and an offline, desktop version. Raspberry Pi has updated most of their material including Scratch 3 versions of all projects in the Code Club Scratch Modules 1–3 and the CoderDojo Scratch Sushi Cards. Harvard has already updated their Creative Computing Curriculum to take advantage of the new features. While much of the educational material have been updated to Scratch 3, work is still in progress to finish the remaining items. While projects can be run on tablets and phones with this new version, there is no support for creating projects on phones at this time. This change allows Scratch to be used on a wider variety of devices, including tables and phones. With the release of Scratch 3, Scratch no longer requires Flash to run as it has been rewritten entirely in HTML and JavaScript. There were changes to the paint editor as well, including a new layout, an eraser that works in vector mode, more control over vectors (including curve handles and a point mode), and additional layer control (such as bring to front). The sound editor was improved with a new recording system, improved audio trimming functionality, and new sound effects such as faster, slower, echo, and robot. Some of the new blocks introduced with Scratch 3 cover features such as enhanced operators for manipulating strings, new pen blocks (including a transparent pen), and a glide block (that allows for more easily moving to a location). They are planning for experimental extensions to replace the functionality provided by ScratchX. This type of extension will be for individual use only and will not be able to be shared. In addition to these formal extensions, support for experimental extensions is in the works. Once available, extensions will be able to be submitted to the Scratch team for review and approval before being added to the extensions library. The Scratch team is working on releasing guidelines and specifications for submitting user-created extensions. Once added to a project, new code blocks will be added that can be used in the editor. ![]() Extensions are all reviewed and approved by the Scratch team. Currently provides in the library are collaborations with micro:bit, JoyLabz, Google, Lego, and AWS. Scratch 3 introduces a new extensions system that provides collections of extra blocks to interact with physical devices and web services. Updated Scratch 3 interface (credit: Raspberry Pi) Raspberry Pi Code Club produced a printable poster to help users navigate the new layout. The code blocks are now larger to help address issues that new users had clicking and dragging the blocks. The new layout sees the stage move to the right-hand side of the UI similar to how it was in Scratch 1.2. ![]() Scratch 3 is available in both online and offline versions and can now be run on tablets. The new version of Scratch has been rewritten in HTML5 and JavaScript and no longer requires Flash. Scratch 3 brings changes to the look and feel of the Scratch layout, new paint and editing tools, new code blocks, and a new extensions system. MIT released the latest version of their visual programming language Scratch on January 2.
