GNU Guile 2.9.8 (beta) released

Andy Wingo — January 2, 2020

We are delighted to announce the release of GNU Guile 2.9.8. This is the eighth and possibly final pre-release of what will eventually become the 3.0 release series.

See the release announcement for full details and a download link.

This release fixes an error in libguile that could cause Guile to crash in some particular conditions, and was notably experienced by users compiling Guile itself on Ubuntu 18.04.

We plan to release a final Guile 3.0.0 on 17 January, though we may require another prerelease in the meantime. However until then, note that GNU Guile 2.9.8 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.

As always, experience reports with GNU Guile 2.9.8, good or bad, are very welcome; send them to If you know you found a bug, please do send a note to Happy hacking!
