guile-gi v0.3.0 released

[Mike Gran]

On behalf of the Guile-GI team, I am pleased to announce the release
of Guile-GI v0.3.0.

This library hopes to make GTK3 and WebKit2 available to Guile.

guile-gi is a library that autogenerates GNU Guile bindings for
GObject libraries that provide typelib files.  GObject is a standard
way of writing C-language libraries with headers and introspection
information.  Typelib files are GObject's standard way to provide that
introspection information. Among the GObject libraries are GTK3 and
WebKitGTK2, two popular GUI libraries.

Guile-GI is of beta quality.  Its API is stabilizing, but is not
stable.

The NEWS

    mutation sigil `!'
