+## [3.1.1] - 2024-01-29
+
+Hi everyone!
+
+This is the VOLK v3.1.1 release! We want to thank all contributors. This release wouldn't have been possible without them.
+
+This is a maintenance release to fix subtle bugs in many areas and to improve our tests where possible. All in all, our CI is more stable now and catches more errors.
