Ukukhutshwa kweChrome 78

uphando thaca ukukhutshwa komkhangeli wewebhu Chrome 78. Ngaxeshanye iyafumaneka ukukhululwa okuzinzileyo kweprojekthi yasimahla Chromium, esebenza njengesiseko seChrome. Isikhangeli seChrome hlukile ukusetyenziswa kweempawu zikaGoogle, ubukho benkqubo yokuthumela izaziso kwimeko yokuphazamiseka, ukukwazi ukukhuphela imodyuli yeFlash kwisicelo, iimodyuli zokudlala umxholo wevidiyo okhuselweyo (DRM), inkqubo yokufaka ngokuzenzekelayo uhlaziyo kunye nokuhanjiswa ngexesha lokukhangela. Iiparamitha zeRLZ. Ukukhutshwa okulandelayo kweChrome 79 kucwangciselwe uDisemba 10.

Siseko utshintsho Π² chrome 78:

  • Iphunyeziwe inkxaso yovavanyo "ye-DNS phezu kwe-HTTPS" (i-DoH, i-DNS phezu kwe-HTTPS), eya kwenziwa ngokukhethiweyo kwiindidi ezithile zabasebenzisi abaneesethingi zenkqubo esele zibonisa ababoneleli be-DNS abaxhasa i-DoH. Umzekelo, ukuba umsebenzisi une-DNS 8.8.8.8 echazwe kwiisetingi zesistim, ngoko inkonzo ye-Google ye-DoH (β€œhttps://dns.google.com/dns-query”) iya kwenziwa isebenze kwiChrome ukuba i-DNS yi-1.1.1.1. XNUMX, emva koko inkonzo ye-DoH Cloudflare ("https://cloudflare-dns.com/dns-query"), njl.

    Ukulawula ukuba i-DoH yenziwe yasebenza na, i-"chrome://flags/#dns-over-https" useto lunikiwe. Iindlela ezintathu zokusebenza zixhaswa: zikhuselekile, zizenzekelayo kwaye zivaliwe. Kwimowudi "ekhuselekileyo", iinginginya zimiselwa kuphela ngokusekelwe kumaxabiso akhuselweyo agcinwe ngaphambili (afunyenwe ngoqhagamshelo olukhuselekileyo) kwaye izicelo nge-DoH yokubuyela umva kwi-DNS eqhelekileyo ayisetyenziswa. Kwimo "ezenzekelayo", ukuba i-DoH kunye ne-cache ekhuselekileyo ayifumaneki, idatha inokufunyanwa kwi-cache engakhuselekanga kwaye ifikeleleke nge-DNS yendabuko. Kwimodi "yokucima", i-cache ekwabelwana ngayo ihlolwe kuqala kwaye ukuba akukho datha, isicelo sithunyelwa nge-DNS yenkqubo.

  • Izixhobo zongqamaniso ngoku zinenkxaso yokuqala yeebhodi eziqhotyoshwayo ekwabelwana ngazo, kodwa azikavulwa kubo bonke abasebenzisi.

Inqaku lesixhobo ngoku livela njengebhloko ephumayo ebonisa isicatshulwa esipheleleyo sesihloko kunye ne-URL yephepha. Ibhloko isebenziseka ngokukhawuleza ukufumana iphepha elifunwayo xa uvula inani elikhulu kakhulu leethebhu (endaweni yokudlula kwiithebhu, ungahambisa imouse phezu kwendawo yolawulo ngeethebhu kwaye ufumane iphepha olikhangelayo). Kwixesha elizayo, kucwangciswe ukubonisa i-thumbnail yephepha kule block;
  • Yongezwe into yovavanyo (chrome://flags/#enable-force-dark) ukunyanzela ukusetyenziswa komxholo omnyama xa ujonga iiwebhusayithi. Ukuqinisekisa umboniso omnyama wesayithi, imibala iyaguqulwa;
  • Yongeziwe inkxaso yengcaciso IiPropati zeCSS kunye neNqanaba loku-1 le-API, ekuvumela ukuba ubhalise iipropati zakho ze-CSS ezihlala ziluhlobo oluthile, zikuvumela ukuba ubeke ixabiso elingagqibekanga, kwaye ikuvumela ukuba ubophe iziphumo zoopopayi. Ukubhalisa ipropati, ungasebenzisa indlela yerejistaProperty () okanye "@property" umgaqo weCSS, umzekelo:

    CSS.registerProperty({
    igama: "--ubungakanani befonti",
    isintaksi: "β€Ήubudeβ€Ί",
    Ixabiso lokuqala: "0px",
    ilifa: bubuxoki
    });

  • Kwimo yovavanyo lweMvelaphi (iifitsha zovavanyo ezifuna ukwahluka ukusebenza) ii-API ezininzi ezintsha ziye zacetywa. Uvavanyo lwemvelaphi luthetha ukukwazi ukusebenza kunye ne-API echaziweyo kwizicelo ezikhutshelwe kwi-localhost okanye i-127.0.0.1, okanye emva kokubhalisa kunye nokufumana ithokheni ekhethekileyo esebenzayo ixesha elilinganiselweyo kwindawo ethile.
