Software Update: Racket 8.3

Racket is a development language with which other development languages ​​can be developed. In addition, you can simply develop in Racket itself. It was previously known as the PLT Scheme and comes from the Lisp-Scheme family. For the background we refer to the manifest, written under the direction of Matthias Felleisen. The developers have released version 8.3 of Racket and the changelog for that release looks like this:
