Funktionen er tilg\u00e6ngelig for YouTube, Music, Spotify samt nogle andre apps.\n<li class=\"l\"> Indstillingerne er blevet forbedret med mulighed for at aktivere eller deaktivere underst\u00f8ttelse af acceleration for musen.\n<li class=\"l\"> Mulighederne for brugen af virtuelle skriveborde er blevet udvidet. N\u00e5r en ny link \u00e5bnes, \u00e5bnes den nu altid p\u00e5 den nuv\u00e6rende virtuelle skrivebord, hvilket g\u00f8r det lettere at opdele brugerens arbejdsrum.\n<li class=\"l\"> Der er introduceret en ny oversigtsfunktion til tablets, der g\u00f8r det muligt at rulle let gennem \u00e5bne vinduer p\u00e5 touchsk\u00e6rmen. Denne funktion fungerer ogs\u00e5 godt p\u00e5 mindre sk\u00e6rme. For at opdele sk\u00e6rmen er det nok at trykke l\u00e6nge p\u00e5 vinduet, hvorefter vinduet kan flyttes til venstre eller h\u00f8jre side.\n<li class=\"l\"> Unified application management in the settings \u2014 a new App Management section has been introduced for changing application settings and access rights;\n<li class=\"l\"> I Crostini-subsystemet, der er designet til at k\u00f8re Linux-apps, er der blevet fjernet restriktioner for netv\u00e6rksportnumre, der kan bruges til at starte netv\u00e6rksbehandlere i Linux-milj\u00f8et (for eksempel til test af web-apps), der er bundet til det lokale netv\u00e6rksinterface (localhost). I den n\u00e6ste udgave, Chrome OS 80, forventes det, at den grundl\u00e6ggende Linux-milj\u00f8 bliver opdateret til Debian 10 komponenter (i \u00f8jeblikket anvendes Debian 9) og muligheden for USB-enheder, der kan benyttes i Linux-milj\u00f8et.\n<li class=\"l\"> For lokalt tilsluttede printere er der tilf\u00f8jet et afsnit med avancerede indstillinger til forh\u00e5ndsvisningsvinduet, som giver mulighed for at \u00e6ndre PPD-attributter i CUPS, s\u00e5som h\u00e6ftekligning, perforering, valg af papirbakke osv.<br \/>\nI en af de kommende udgaver forventes muligheden for at udskrive via forbindelser til eksterne printservere.<\/p>\n<li class=\"l\"> I ARC++-milj\u00f8et (App Runtime for Chrome, et lag til at k\u00f8re Android-apps i Chrome OS) er adgangen til Google Play-kataloget som standard aktiveret. F\u00f8rhen var Google Play som standard deaktiveret og kunne kun fungere i en tilstand, der tilb\u00f8d et begr\u00e6nset udvalg af apps. Dette begr\u00e6nsning er nu fjernet, og Google Play er blevet tilg\u00e6ngeligt for alle virksomhedskonti, uden behov for administratorautorisation.\n<li class=\"l\"> <noindex><a rel=\"nofollow\" href=\"https:\/\/blog.chromium.org\/2019\/10\/dm-verity-algorithm-change.html\">metoden til synkronisering af indstillinger \u00e6ndret via about:config-gr\u00e6nsefladen.

For eksempel kr\u00e6ver synkronisering af parameteren browser.some_preference, at v\u00e6rdien \u00abservices.sync.prefs.sync.browser.some_preference\u00bb s\u00e6ttes til true.

Ikke desto mindre blev det besluttet at erstatte SHA-1 med den mere p\u00e5lidelige SHA256-algoritme. For at undg\u00e5 at bremse opstartsprocessen, da SHA256 kr\u00e6ver flere ressourcer til beregning, er der foretaget talrige optimeringer, som har gjort det muligt at opn\u00e5 en ydeevne, der er
