Being free and open source allows others to contribute to the project by adding new features or fixing bugs.
Alpha, Beta, and Stable releases will be prebuilt from a specific commit that will be listed and provided with the checksum for convenience.
Unnamed Block's original goal was to provide new programmers with a fast open source platform to learn how programs work. Since its creation, its focus has shifted towards more advanced features where any developer can use Unnamed Blocks as a platform to make utilities and games on.
Projects from other universities like Scratch from MIT and Snap from Berkeley aim to provide an entry to programming by using blocks in a very user friendly way. These lack more advanced features and stop short of any practical use. There also very restrictive in how they function and very slow when it comes to performance.
The solution to these problems is to make an open source, fast, multi feature set, moddable program that anyone can use. Mods can be subscribed to that fit the users goal with using the platform. Whether that be learning, simple game development, or using advanced feature sets. Tutorials and documentation will be available for mods and the editor to provide information or teach you the first steps in programming whatever you want.
In the past decade there has been a push for industries using technology to improve how they operate and their product output. This dependence will continue to grow as research into CS makes things possible that have never been done. With the right feature set, Unnamed Blocks can be a great tool for creating things quickly that are very performant and are easy to configure and modify.
