We are pleased to announce GNU Guile 1.9.12, the thirteenth and one of the last pre-releases before 2.0, featuring a compiler and virtual machine and a large set of exciting new features. As usual feedback, bug reports, portability issues, etc., are all welcome!
Summer holidays in this hemisphere reduced the release pace, though the list of news and bug fixes is pretty long. These changes bring us closer to our expectations for 2.0.
Among other things 1.9.12 comes with a new "recursive REPL" for debugging (similar to Emacs' recursive editing levels), improvements to the dynamic foreign function interface (FFI), and various R6RS bug fixes.
See http://lists.gnu.org/archive/html/guile-devel/2010-09/msg00033.html for the original announcement.
