+## [3.1.2] - 2024-02-25
+
+Hi everyone!
+
+This is the VOLK v3.1.2 release! We want to thank all contributors.
+This release wouldn't have been possible without them.
+
+The last maintenance release revealed issues in areas that are difficult to test. 
+While the changes to the library should be minimal, usability should be improved. 
+Most notably, we build and deploy [the VOLK documentation](https://www.libvolk.org/docs) 
+automatically now.
