A fost lansat\u0103 versiunea 4.2.2 a sistemului de operare Qubes, care implementeaz\u0103 ideea utiliz\u0103rii unui hypervisor pentru izolarea strict\u0103 a aplica\u021biilor \u0219i componentelor sistemului de operare (fiecare clas\u0103 de aplica\u021bii \u0219i serviciile de sistem func\u021bioneaz\u0103 \u00een ma\u0219ini virtuale separate). Pentru func\u021bionare, se recomand\u0103 un sistem cu 16 GB RAM (minim \u2014 6 GB) \u0219i un CPU Intel sau AMD pe 64 de bi\u021bi care suport\u0103 tehnologia VT-x cu EPT\/AMD-v cu RVI \u0219i VT-d\/AMD IOMMU, preferabil cu un GPU Intel (GPU-urile NVIDIA \u0219i AMD nu au fost testate suficient de bine). Dimensiunea imaginii de instalare este de 6 GB (x86_64). <\/p>\n

Aplica\u021biile din Qubes sunt \u00eemp\u0103r\u021bite \u00een clase \u00een func\u021bie de importan\u021ba datelor procesate \u0219i de sarcinile rezolvate. Fiecare clas\u0103 de aplica\u021bii (de exemplu, munc\u0103, divertisment, opera\u021biuni bancare), precum \u0219i serviciile sistemului (subsystema de re\u021bea, firewall-ul, gestionarea stoc\u0103rii, stiva USB etc.) func\u021bioneaz\u0103 \u00een ma\u0219ini virtuale separate virtu\u00e1lne ma\u0161ini<\/a>, lansate utiliz\u00e2nd hypervisorul Xen. Aceste aplica\u021bii sunt disponibile \u00eentr-un singur desktop \u0219i sunt eviden\u021biate pentru claritate cu diferite culori ale marginii feronierului. Fiecare mediu are acces \u00een citire la sistemul de fi\u0219iere r\u0103d\u0103cin\u0103 bazal \u0219i la stocarea local\u0103, care nu se suprapune cu stoc\u0103rile altor medii; pentru a organiza interac\u021biunea aplica\u021biilor se folose\u0219te un serviciu special. <\/p>\n<\/p>\n

Ca baz\u0103 pentru formarea mediilor virtuale poate fi utilizat\u0103 baza de pachete Fedora \u0219i Debian, de asemenea, comunitatea suport\u0103 \u0219abloane pentru Ubuntu, Gentoo \u0219i Arch Linux. Este posibil\u0103 organizarea accesului la aplica\u021biile dintr-o ma\u0219in\u0103 virtual\u0103 cu Windows, precum \u0219i crearea ma\u0219ini virtuale<\/a> pe baza Whonix pentru a asigura un acces anonim prin Tor. Interfa\u021ba utilizatorului este construit\u0103 pe baza Xfce. C\u00e2nd utilizatorul porne\u0219te o aplica\u021bie din meniu, aceast\u0103 aplica\u021bie se porne\u0219te \u00eentr-o anumit\u0103 ma\u0219in\u0103 virtual\u0103. Con\u021binutul mediilor virtuale este determinat de un set de \u0219abloane. <\/p>\n

Noua versiune aduce actualiz\u0103ri ale versiunilor programelor care formeaz\u0103 mediul de sistem de baz\u0103 (dom0). A fost preg\u0103tit un \u015fablon pentru crearea de medii virtuale bazate pe Fedora 40. <\/p>\n

\u00cen ramura 4.2, pentru a proteja \u00eempotriva atacurilor legate de manipularea simbolurilor unicode \u0219i codurilor de caractere incorecte \u00een numele fi\u0219ierelor, au fost introduse restric\u021bii legate de utilizarea caracterelor extinse \u00een numele fi\u0219ierelor. Aceast\u0103 modificare a dus la probleme cu copierea \u0219i mutarea fi\u0219ierelor care con\u021bin litere ne-latine \u00een nume. \u00cen versiunea 4.2.2, comportamentul vechi \u00een tratamentul denumirilor fi\u0219ierelor a fost restabilit \u00een mod implicit, iar pentru configurare, \u00een serviciul qubes.Filecopy a fost ad\u0103ugat parametrul \u201eallow-all-names\u201d.
