STklos is a free Scheme System conforming to R5RS. The implementation is based on an ad-hoc Virtual Machine. It can also be compiled as a library, so that one can easily embed it in an application. Its features include an efficient and powerful object system based on CLOS, a simple-to-use module system, implementation of the full tower of numbers defined in R5RS, and easy connection to the GTK+ toolkit. STklos is the successor of STk, a Scheme interpreter tightly connected to the Tk toolkit.

Release Notes: This release supports UTF-8 encoding and begins to support some (future) R7RS traits. It includes full support for UTF-8 strings and symbols, support for Win32 under Cygwin, support for Mac OS X Lion, and some bugfixes.
Release Notes: This is mainly a maintenance version. Changes include documentation updates, modifications to support ScmPkg on MacPorts, fixes for incompatibilities in FFI introduced in 1.00, better x86_64 support, and bugfixes.
Release Notes: The main difference with this version and the pre-1.0 ones is that it does not integrate GTK+ 1.x support. In fact, GTK+ support is now available through several ScmPkg packages. GMP-lite was completely rewritten. Functions can now have documentation strings. GNU readline support was added in REPL if the readline library can be loaded dynamically. The location of configuration files can now be changed. An interactive help system was added. Newly implemented SRFIs include 74, 96, 98, and 100. New primitives include port?, help, make-directories, and ensure-directories-exist. Bugs were fixed.
Release Notes: The C/invoke FFI library has been replaced by libffi. Now Gtk2 ScmPkg packages work on Mac OS. The option --build-sync-file has been added to ease personal ScmPkg repository maintenance. There are some bugfixes.
Release Notes: Support for recent versions of SLIB was fixed. The stklos-pkg command was improved. Several mutexes bugs were fixed. Minor improvements were made to the FFI. PCRE was updated to version 7.4. SRFIs were implemented (SRFI-45, SRFI-59, SRFI-88, SRFI-89). Bugs were fixed.
