+* x86: Latest version of all CPU models how have TSX (HLE and RTM)
+  disabled by default
+* x86: Support for AVX512 BFloat16 extensions
+* x86: VMX features exposed more accurately and controllably
+* s390: TCG now implements IEP (Instruction Execution Protection)
+* PowerPC: POWER8 and POWER9 non-virtualized machines separated out
+* PowerPC: RTAS now comes from SLOF instead of QEMU itself
+* PowerPC: Unplug of multifunction PCI devices now unplugs the
+  whole slot, as in x86
+* ARM: Support for >256 CPUs with KVM is fixed
+* ARM: Memory hotplug now supported , when using UEFI, ACPI, for
+  virt machine type
+* ARM: SVE support possuble now for KVM guests
+* ARM: ACPI generic event device can now deliver powerdown event
+* The backend device can be specified for a guest audio device
+* virtio v1.1 packed virtqueues supported
+* Socket based character device backends now support TCP keep-alive
+* Use encryption library cipher mode facilities, allowing improved
+  performance for eg. AES-XTS encrption
