We are pleased to announce GNU Guile release 2.1.7, the next pre-release in what will become the 2.2 stable series.
This release fixes bugs related to migrating coroutines between threads. It is an incremental release along the path to 2.2. We hope to be able to release a final 2.2.0 within a few weeks.
