Dostupan je izdanak operativnog sustava Qubes 4.2.2, koji implementira ideju kori\u0161tenja hipervizora za strogu izolaciju aplikacija i komponenti sustava (svaka klasa aplikacija i sustavske usluge rade u odvojenim virtualnim ma\u0161inama). Preporu\u010duje se sustav s 16 GB RAM-a (minimum - 6 GB) i 64-bitnim CPU Intel ili AMD s podr\u0161kom za tehnologije VT-x s EPT\/AMD-v s RVI i VT-d\/AMD IOMMU; po\u017eeljno je imati Intel GPU (NVIDIA i AMD GPU nisu dovoljno dobro testirani). Veli\u010dina instalacijskog imaga - 6 GB (x86_64). <\/p>\n

Aplikacije u Qubesu su podijeljene u klase ovisno o va\u017enosti obra\u0111enih podataka i zadatcima koji se rje\u0161avaju. Svaka klasa aplikacija (npr. posao, zabava, bankovne transakcije), kao i sustavske usluge (mre\u017eni podsustav, vatrozid, rad s pohranjivanjem, USB stog itd.), rade u odvojenim virtualnim ma\u0161inama<\/a>, pokretanim kori\u0161tenjem hiper-vizora Xen. Pri tome navedene aplikacije su dostupne unutar jednog radnog stola i isti\u010du se razli\u010ditim bojama okvira prozora. Svako okru\u017eenje ima pristup samo za \u010ditanje osnovnom korijenskom datote\u010dnom sustavu i lokalnoj pohrani, koja se ne preklapa s pohranama drugih okru\u017eenja, za organizaciju interakcije aplikacija koristi se posebna usluga. <\/p>\n<\/p>\n

Kao osnova za stvaranje virtualnih okru\u017eenja mo\u017ee se koristiti bazni paket Fedora i Debian, tako\u0111er zajednica podr\u017eava predlo\u0161ke za Ubuntu, Gentoo i Arch Linux. Mogu\u0107e je organizirati pristup aplikacijama u virtualnoj ma\u0161ini s Windowsom, kao i kreirati virtualnih ma\u0161ina<\/a> na bazi Whonix za omogu\u0107avanje anonimnog pristupa putem Tora. Korisni\u010dko su\u010delje izgra\u0111eno je na Xfce-u. Kada korisnik pokrene aplikaciju iz izbornika, ta aplikacija se pokre\u0107e u odre\u0111enoj virtualnoj ma\u0161ini. Sadr\u017eaj virtualnih okru\u017eenja odre\u0111uje se skupom predlo\u017eaka. <\/p>\n

U novom izdanju istaknuto je a\u017euriranje verzija programa koje \u010dine osnovno sustavno okru\u017eenje (dom0). Pripremljen je predlo\u017eak za formiranje virtualnih okru\u017eenja na bazi Fedora 40. <\/p>\n

U grani 4.2 uvedena su ograni\u010denja za za\u0161titu od napada povezanih s manipulacijom unicode simbolima i neispravnim kodovima simbola u imenima datoteka, vezana uz upotrebu pro\u0161irenih simbola u imenima datoteka. Ova promjena dovela je do problema s kopiranjem i premje\u0161tanjem datoteka koje sadr\u017ee nelatini\u010dna slova u imenu. U verziji 4.2.2 po defaultu je vra\u0107eno staro pona\u0161anje pri obradi imena datoteka, a za postavku je u uslugu qubes.Filecopy dodan parametar \u00aballow-all-names\u00bb.
