We are delighted to announce GNU Guile 2.9.5, the fifth beta release in preparation for the upcoming 3.0 stable series. See the release announcement for full details and a download link.
Besides the usual set of optimizations, this release adds an --r6rs
option for better R6RS support out of the box, and also adds a new
--r7rs corresponding to R&RS. Guile's core exception handling has
also been rebased onto the raise-exception and
with-exception-handler primitives, enabling better compatibility going
forward with structured exception objects, which are more common in the
broader Scheme community than Guile's old throw and catch.
GNU Guile 2.9.5 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 2.9.5, 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!
