- Implemented support for x86 ISA extensions, Bochs is aligned with latest
published Intel Archicture Manual (rev 039, AVX rev 011):
- XSAVEOPT, AVX/AVX2/F16C, BMI1/BMI2, SMEP, SSE4A (AMD), INVPCID
- VMX: VMX Preemption Timer and Pause Loop Exiting VMEXIT controls
- TODO: FMA, XOP (AMD), SVM (AMD)
- Networking: introduced new networking module 'slirp'
