After about two-year hard work, mBlock 5 has been greatly enhanced, and more and more people are choosing mBlock 5 to teach and learn computer programming.


Based on mBlock 3, mBlock 5 has been optimized in the user interface, separated stage sprites from devices, and provided more practical and playful features to improve your coding experience. We highly recommend you mBlock 5 for teaching and learning code. Please note that it will not replace mBlock 3. You can still use both mBlock 5 and mBlock 3.


Below are the main new features of mBlock 5.

Note:

The mBlock 3 web editor has to run with Flash Player. And since Adobe Inc. has announced that it will stop updating and distributing the Flash Player at the end of 2020, the mBlock 3 web editor will no longer work on mainstream browsers, such as Chrome, Apple Safari, Microsoft Edge, IE, and Mozilla by then. (For details about the announcement of Adobe Inc., visit https://theblog.adobe.com/adobe-flash-update/.)


Besides, with the release of macOS Catalina 10.15, 32-bit app support is no longer available. Thus mBlock 3 Mac version will fail to run on macOS Catalina 10.15 and later versions of macOS.

Please note that mBlock 3 desktop version can still run properly in the Windows XP, 7, 8, and 10 systems and macOS systems earlier than 10.15.
