This version of Scheme has been divided into a small language, suitable for educators, researchers, and users of embedded languages; and a large language focused on the practical needs of mainstream software development.<p>&gt;The report on the small language was finalized on July 6, 2013. It is available in PDF format and as LaTeX source code. There are errata.<p>&gt;The development of the large language is still in progress. For details on the development process of both languages, see the ​Scheme Reports home page and the Working Groups home page.
