– The Tiny Code Generator (TCG) supports more instructions on LoongArch like SC.Q, LLACQ/SCREL, and estimated reciprocal instructions.

– RISC-V on QEMU 11.0 also now supports the ZALASR extension, Zilsd and Zclsd extensions and Smpmpmt.

– Support for the MIPS P8700 CPU.

– The CPU model for Intel Xeon Diamond Rapids is added.

– A new “nitro” accelerator can be used with the new nitro machine for supporting AWS Nitro Enclaves natively under QEMU.

– QEMU 11.0 on KVM now supports Control-flow Enforcement Technology (CET) virtualization.

– AMD SEV-SNP and Intel TDX machines with KVM can now be reset on QEMU 11.0.
