 ## [Unreleased]
+### Changed
+- VMs running via QEMU only expose SSE and SSE2 CPU features ([#60](https://github.com/cross-platform-actions/action/issues/60)).
+    This changes the machine to `q35` and the cpu to `max`, for x86-64 using
+    the QEMU hypervisor. This adds more CPU features like AVX and AVX2.
