We are delighted to announce GNU Guile 2.9.4, the fourth beta release in preparation for the upcoming 3.0 stable series. See the release announcement for full details and a download link.
This release enables inlining of references to top-level definitions
within a compilation unit, speeding up some programs by impressive
amounts. It also improves compilation of floating-point routines like
sin, implements the Ghuloum/Dybvig "Fixing Letrec (reloaded)"
algorithm, and allows mixed definitions and expressions within lexical
contours, as is the case at the top level. Try it out, it's good times!
GNU Guile 2.9.4 is a beta release, and as such offers no API or ABI stability guarantees. Users needing a stable Guile are advised to stay on the stable 2.2 series.
Experience reports with GNU Guile 2.9.4, good or bad, are very welcome;
send them to guile-devel@gnu.org. If you know you found a bug, please
do send a note to bug-guile@gnu.org. Happy hacking!
