+## [3.1.0] - 2023-12-05
+
+Hi everyone!
+
+This is the VOLK v3.1.0 release! We want to thank all contributors. This release wouldn't have been possible without them.
+
+This release introduces new kernels, fixes a lot of subtle bugs, and introduces an updated API that allows VOLK to run on PowerPC and MIPS platforms without issues. Namely, complex scalar values are passed to kernels by pointer instead of by value. The old API is still around and will be for the whole VOLK v3 release cycle. However, it is recommended to switch to the new API for improved compatibility. Besides, we saw improvements to our `cpu_features` usage that should make it easier for package maintainers. Finally, a lot of tests received fixes that allow our CI to run without hiccups.
