We are pleased to announce GNU Guile release 3.0.6, the latest in the
3.0 stable release series.
Compared to the previous release in the 3.0 series, Guile 3.0.6 improves
source-location information for compiled code, removes the dependency on
libltdl, fixes some important bugs, adds an optional bundled "mini-gmp"
library, as well as the usual set of minor optimizations and bug fixes.
Compared to the previous stable series (2.2.x), Guile 3.0 adds support
for just-in-time native code generation, speeding up all Guile programs.
See the NEWS extract at the end of the mail for full details.
The Guile web page is located at http://gnu.org/software/guile/, and
among other things, it contains a copy of the Guile manual and pointers
to more resources.
Guile is an implementation of the Scheme programming language, packaged
for use in a wide variety of environments. In addition to implementing
the R5RS, R6RS, and R7RS Scheme standards, Guile includes full access to
POSIX system calls, networking support, multiple threads, dynamic
linking, a foreign function call interface, powerful string processing,
and HTTP client and server implementations.
Guile can run interactively, as a script interpreter, and as a Scheme
compiler to VM bytecode. It is also packaged as a library so that
applications can easily incorporate a complete Scheme interpreter/VM.
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.
Guile 3.0.6 can be installed in parallel with Guile 2.2.x; see
http://www.gnu.org/software/guile/manual/html_node/Parallel-Installations.html.

Changes in 3.0.6 (since 3.0.5)
* Notable changes
** Reimplement dynamic library loading ("dlopening") without libltdl
Guile used to load dynamic libraries with libltdl, a library provided by
the Libtool project.
Libltdl provided some compatibility benefits when loading shared
libraries made with older toolchains on older operating systems.
However, no system from the last 10 years or so appears to need such a
thick compatibility layer.
Besides being an unmaintained dependency of limited utility, libltdl
also has the negative aspect that in its search for libraries to load,
it could swallow useful errors for libraries that are found but not
loadable, instead showing just errors for search path candidates that
are not found.
Guile now implements dynamic library loading directly in terms of the
standard "dlopen" interface, providing a limited shim for platforms with
similar functionality exposed under different names (MinGW).
This change has a few practical impacts to Guile users. There is a new
library search path variable, `GUILE_EXTENSIONS_PATH'. Also, errors when
loading a library fails now have better errors. And Guile no longer has
a libltdl dependency.
Although Guile no longer uses libltdl, for backwards compatibility Guile
still adds `LTDL_LIBRARY_PATH' to the loadable library search path, and
includes ad-hoc logic to support uninstalled dynamically loadable
libraries via also adding the ".libs" subdirectories of
`LTDL_LIBRARY_PATH' elements. See "Foreign Libraries" in the
documentation for a full
