This is an announce for the release of JazzScheme 2.3 (www.jazzscheme.org).

JazzScheme is a development system based on extending the Scheme programming
language and the Gambit system. It includes a module system, hygienic
macros,
object-oriented programming, a full featured cross-platform application
framework,
a sophisticated programmable IDE and a build system that creates binaries
for
Mac OS X, Windows and Linux. JazzScheme has been used for more than 10 years
to develop high-quality commercial software.

See http://www.jazzscheme.org/installation.htm for details on installing
JazzScheme
from its public Git repository.
