We are pleased to announce GNU Guile release 1.8.4. This is the next
maintenance release for the 1.8 stable series.

You can find it here:
SHA1 hash: 1e80fe242acfde2bfa39fd1e8409a8f010e24e2b

A GPG detached signature of the package is available at:

The Guile web page is located at,
and among other things, it contains a link to the Guile FAQ and
pointers to the mailing lists.

Guile is an interpreter for the Scheme programming language, with
support for many SRFIs, packaged for use in a wide variety of
environments. In addition to implementing the R5RS Scheme standard,
Guile includes a module system, full access to POSIX system calls,
networking support, multiple threads, dynamic linking, a foreign
function call interface, and powerful string processing.

Guile can run interactively or as a script interpreter, and is also
packaged as a library so that applications can easily incorporate a
complete Scheme interpreter. An application can use Guile as an
extension language, a clean and powerful configuration language, or as
multi-purpose "glue" to connect primitives provided by the
application. It is easy to call Scheme code from C code and vice
versa. Applications can add new functions, data types, control
structures, and even syntax to Guile, to create a domain-specific
language tailored to the task at hand.

This is primarily a bugfix release. Here are the highlights, taken from
the `NEWS' file:

- Bugs fixed

- CR (ASCII 0x0d) is (again) recognized as a token delimiter by the
- Fixed a segmentation fault which occurred when displaying the
backtrace of a stack with a promise object (made by `delay') in it
- Make `accept' leave guile mode while blocking
- `scm_c_read ()' and `scm_c_write ()' now type-check their port
- Fixed a build problem on AIX (use of func_data identifier)
- Fixed a segmentation fault which occurred when hashx-ref or
hashx-set! was called with an associator proc that returns neither
a pair nor #f.
- Secondary threads now always return a valid module for
- Avoid MacOS build problems caused by incorrect combination of "64"
system and library calls.
- `guile-snarf' now honors `$TMPDIR'
- `guile-config compile' now reports CPPFLAGS used at compile-time
- Fixed build with Sun Studio (Solaris 9)
- Fixed wrong-type-arg errors when creating zero length SRFI-4
uniform vectors on AIX.
- Fixed a deadlock that occurs upon GC with multiple threads.
- Fixed compile problem with GCC on Solaris and AIX (use of _Complex_I)
- Fixed autotool-derived build problems on AIX 6.1.
- Fixed NetBSD/alpha support
- Fixed MacOS build problem caused by use of rl_get_keymap(_name)

- New modules (see the manual for details)

- `(srfi srfi-69)'

- Documentation fixes and improvements

- Removed premature breakpoint documentation
- More about Guile's default *random-state* variable
- GOOPS: more about how to use `next-method'

- Changes to the distribution

- Corrected a few files that referred incorrectly to the old GPL +
special exception licence
- Removed unnecessary extra copies of COPYING*

Any bugs found in this release will be addressed by further bugfix
releases numbered 1.8.*.

You can follow Guile development in CVS and on the Guile mailing lists
(see ANON-CVS and HACKING). Guile builds from the development branch
of CVS will have version number 1.9.0.

Guile versions with an odd middle number, e.g., 1.9.*, are unstable
development versions. Even middle numbers indicate stable versions.
This has been the case since the 1.3.* series.

Please send bug reports to `'.

Ludovic Courtès, on behalf of the Guile team.
