- New CPU architectural features emulated:
- FEAT_NMI
- FEAT_CSV2_3
- FEAT_ETS2
- FEAT_Spec_FPACC
- FEAT_WFxT
- The 'max' CPU and any new CPU types will default to a 1GHz generic timer frequency rather than the old 62.5MHz (this is architecturally required from ARMv8.6 onwards)
- The emulated GICv3 also now has NMI support
- Changes to existing board models:
- Add DM163 display to B-L475E-IOT01A board
- xilinx_zynq: The cache controller is now present
- xilinx_zynq: Now supports up to two CPU cores
- sbsa-ref: The default CPU type is now Neoverse-N2

Migration
- New 'exit-on-error' option to migrate-incoming, if set to false causes QEMU to not exit on incoming migration failure, giving the management layer an opportunity to fetch the error through QMP.
