+## [2.2.0] - 2020-02-16
+
+Hi everyone,
+
+we have a new VOLK release v2.2.0!
+
+We want to thank all contributors. This release wouldn't have been possible without them.
+
+We're curious about VOLK users. Especially we'd like to learn about VOLK users who use VOLK outside GNU Radio.
+
+If you have ideas for VOLK enhancements, let us know. Start with an issue to discuss your idea. We'll be happy to see new features get merged into VOLK.
+
+The v2.1.0 release was rather large because we had a lot of backlog. We aim for more incremental releases in order to get new features out there.
+
+### Highlights
+
+VOLK v2.2.0 updates our build tools and adds support functionality to make it easier to use VOLK in your projects.
+
+* Dropped Python 2 build support
+    - Removed Python six module dependency
+* Use C11 aligned_alloc whenever possible
+    - MacOS `posix_memalign` fall-back
+    - MSVC `_aligned_malloc` fall-back
+* Add VOLK version in `volk_version.h` (included in `volk.h`)
+* Improved CMake code
+* Improved code with lots of refactoring and performance tweaks
