Pre-release software is built using actively developed sources.
Binaries are built nightly, and minute-by-minute changes are available
through Development Repository.
Option 1: Installer
(version 5.0.1.5, updated at Thursday, September 02 2010, 03:50 EDT)
Installers:
Racket
Same as the normal distribution, containing the basic
systems and DrRacket.
Racket Textual
A small distribution that contains only Racket and
console applications based on it, including the Racket
web server. No docs and no GUI applications.
Racket Full
Contains the complete Racket tree from the
repository, including full documentation, full
source tree, libraries that are not completely stable,
and esoteric material.
Note: the default installation directory contains the version
number to avoid clobbering a normal installation.
(Under Windows, registry names are different, too.)
