We are pleased to announce GNU Guile 1.9.9, the tenth pre-release of what will soon become the 2.0 stable series, featuring a compiler and virtual machine. If you haven't tried it yet, please do and report back!
This release adds support for delimited and composable continuations, a powerful mechanism that allows part of a program's control flow to be captured and reinstated. Besides, the release focuses on performance and usability improvements as well as bug fixes.
