Version 1.4.0 of guile
Release Notes: Highlights of this release are documentation strings for most procedures, an interactive help function, better performance due to improved garbage collector and other improvements of the evaluator, faster loading speed due to optimizations of the module system, stricter type checking, Guile's native threads can now coexist with POSIX threads, a builtin malloc debugger, plus many bugfixes and improvements.
Other releases
Release Notes: In addition to a number of bugfixes and portability improvements, this release brings new features, including an implementation of SRFI-41 streams and SRFI-45 promises, additional keyword parameters for procedures which open files, new HTTP client procedures, improvement to the numerics code, and bindings for the sendfile libc function.

Release Notes: This release adds a common subexpression elimination optimization pass, asynchronous finalizers, improved error and warning messages, HTTP/1.1 chunked transfer coding, and SRFI-14 character sets updated to Unicode 6.1. As usual, there are also many build and bug fixes, including one for a long-standing severe memory leak in applicable SMOBs.
Release Notes: New features include Cross-compilation, backwards compatible local-eval, syntax-parameters, new macros 'when' and "unless', default values for fluids, garbage collector tuning, a current-warning-port, locale-aware command line parsing, and of course the usual host of bugfixes.
Release Notes: This release adds a new partial evaluator optimizer which performs constant folding, dead code elimination, copy propagation, and inlining, a new (Web client) module, a new define-syntax-rule macro, more helpful "guild help", fewer calls to "stat", the ability for users to install compiled ".go" files, and, as usual, a whole host of bugfixes.
