U lan\u00e7uar versioni i projektit QEMU 7.0. Si nj\u00eb emulues, QEMU lejon t\u00eb ekzekutoni nj\u00eb program t\u00eb nd\u00ebrtuar p\u00ebr nj\u00eb platform\u00eb harduerike n\u00eb nj\u00eb sistem me nj\u00eb arkitektur\u00eb krejt\u00ebsisht t\u00eb ndryshme, p\u00ebr shembull, t\u00eb ekzekutoni nj\u00eb aplikacion p\u00ebr ARM n\u00eb nj\u00eb PC t\u00eb pajtuesh\u00ebm me x86.
