We are pleased to announce GNU Guile 1.9.13, the fourteenth 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!
Among others, this release comes with new debugging facilities at the REPL (breakpoints, tracepoints, stepping), several new SRFI implementations, and many bug fixes.
