GNU Guile 2.9.2 (beta) released

Andy Wingo — May 23, 2019

We are delighted to announce GNU Guile 2.9.2, the second beta release in preparation for the upcoming 3.0 stable series. See the release announcement for full details and a download link.

This release extends just-in-time (JIT) native code generation support to the ia32, ARMv7, and AArch64 architectures. Under the hood, we swapped out GNU Lightning for a related fork called Lightening, which was better adapted to Guile's needs.

GNU Guile 2.9.2 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.

Users on the architectures that just gained JIT support are especially encouraged to report experiences (good or bad) to If you know you found a bug, please do send a note to Happy hacking!
