Ubuntu 20.04 ukukhutshwa kwe-beta

Yaziswa ukukhutshwa kwe-beta yokusasazwa kwe-Ubuntu 20.04 “Focal Fossa”, ephawule ukukhenkciswa ngokupheleleyo kwesiseko sedatha yephakeji kwaye yadlulela kuvavanyo lokugqibela kunye nokulungiswa kwebug. Ukukhutshwa, okuchazwa njengenkxaso yexesha elide (LTS) ukukhutshwa, apho uhlaziyo lwenziwa kwithuba leminyaka emi-5, lucwangciselwe i-23 ka-Apreli. Imifanekiso yovavanyo esele yenziwe yenzelwe Ubuntu, Ubuntu Server, Lubuntu, Kubuntu, Ubuntu Mate, Ubuntu
Budgie, Ubuntu Studio, Xubuntu kunye no-UbuntuKylin (uhlelo lwaseTshayina).

Siseko utshintsho:

• Idesktop ihlaziywe ngaphambi kokukhululwa GNOME 3.36. Umxholo weYaru ongagqibekanga uhlengahlengiswe, apho, ukongeza kubumnyama obukhoyo ngaphambili (iintloko ezimnyama, imvelaphi emnyama kunye nolawulo olumnyama) kunye nokukhanya (iintloko ezimnyama, imvelaphi ekhanyayo kunye nolawulo lokukhanya), inketho yesithathu yokukhanya ngokupheleleyo iya kuvela. Uyilo olutsha lwemenyu yesixokelelwano kunye nemenyu yesicelo sele icetyiwe. Kongezwe ii-icon zolawulo olutsha ezilungiselelwe ukuboniswa kukukhanya kunye nemvelaphi emnyama.
  

  Ujongano olutsha luphunyeziwe ekutshintsheni iinketho zomxholo.

  

• Ukusebenza kwe-GNOME Shell kunye nomphathi wefestile iye yalungiswa. Umthwalo ocuthiweyo we-CPU kunye nolibaziseko olucuthiweyo ngexesha lonikezelo lopopayi xa kusenziwa iifestile, ukuhambisa imawusi, kunye nokuvula imowudi yokujonga.
• Inkxaso eyongeziweyo ye-10-bit yobunzulu bombala.
• Kwi-X11, inkxaso yokulinganisa ngokweqhezu sele iphunyeziwe, ebifumaneka ngaphambili kuphela xa usebenzisa i-Wayland. Eli nqaku likuvumela ukuba ukhethe ubungakanani obufanelekileyo bezinto kwizikrini ezinoxinano lwepixel ephezulu (HiDPI), umzekelo, unokwandisa izinto ezibonisiweyo zojongano hayi ngamaxesha ama-2, kodwa ngo-1.5.
• Yongeza isikrini esitsha se-splash esivela kwi-boot.
• I-Linux kernel ihlaziywe ukuba ikhululwe 5.4. Njengoko ekukhululweni kwekwindla, i-algorithm ye-LZ4 isetyenziselwa ukucinezela i-kernel kunye nomfanekiso wokuqala we-boot initramf, onciphisa ixesha lokuqalisa ngenxa yokunciphisa idatha ngokukhawuleza.
• Amacandelo enkqubo ehlaziyiweyo kunye nezixhobo zophuhliso: Glibc 2.31, BlueZ 5.53, OpenJDK 11, rustc 1.41, GCC 9.3, Python 3.8.2, ruby ​​​​2.7.0, Ruby kwiRails 5.2.3, php 7.4, 5.30 hamba 1.13.
• Usetyenziso oluhlaziyiweyo lwabasebenzisi kunye nemizobo:
  Mesa 20.0, PulseAudio 14.0-pre, Firefox 74.0, Thunderbird 68.6.0, LibreOffice 6.4

• Usetyenziso oluhlaziyiweyo lweeseva kunye nokubonakala:
  I-QEMU 4.2, i-libvirt 6.0, i-Bind 9.16, i-HAProxy 2.0, i-OpenSSH 8.2 (ngenkxaso ye-FIDO / U2F iithokheni zokuqinisekisa izinto ezimbini). I-Apache httpd inenkxaso ye-TLSv1.3 eyenziwe yasebenza. Inkxaso eyongeziweyo yeVPN WireGuard.

• I-daemon yongqamaniso lwexesha lekhrony ihlaziywe kwinguqulo ye-3.5 kwaye yongezwa yodwa kwinkqubo ngokuqhagamshela isihluzo sokufowuna.
• Ukuphuhliswa kwesakhono sokulinga ukufaka kwi-root partition kunye ne-ZFS iqhubekile. Ukuphunyezwa kwe-ZFSonLinux kuhlaziywe ukukhulula 0.8.3 kunye nenkxaso ye-encryption, ukukhutshwa okushushu kwezixhobo, umyalelo we "zpool trim", ukukhawuleza kwemiyalelo "ye-scrub" kunye ne "resilver". Ukulawula i-ZFS, i-zsys daemon iyaphuhliswa, ekuvumela ukuba usebenzise iinkqubo ezininzi ezihambelanayo kunye ne-ZFS kwikhompyutheni enye, i-automates indalo ye-snapshots kwaye ilawula ukuhanjiswa kwedatha yenkqubo kunye nedatha eguqukayo ngexesha leseshoni yomsebenzisi. Ii-snapshots ezahlukeneyo zinokuqulatha iindlela ezahlukeneyo zenkqubo kwaye zitshintshe phakathi kwazo. Umzekelo, kwimeko yeengxaki emva kokufaka uhlaziyo, ungabuyela kwisimo esidala esizinzileyo ngokukhetha i-snapshot yangaphambili. Izifinyezo zinokusetyenziselwa ukungafihli kunye nokugcina ngokuzenzekela idatha yomsebenzisi.
• Xa kuthelekiswa nokukhutshwa kwe-LTS yangaphambili, iSitolo se-Snap sithathe indawo ye-Ubuntu-software njengesixhobo esingagqibekanga sokufumana kunye nokufaka iiphakheji eziqhelekileyo kunye ne-snap.
• Ukuqulunqwa kweepakethe zoyilo lwe-i386 kumisiwe. Ukuqhubeka nokusebenza kweenkqubo zelifa ezihlala kuphela kwifom ye-32-bit okanye zifuna amathala eencwadi angama-32, ukudibanisa kunye nokuhanjiswa kubonelelwe. iseti eyahlukileyo Iiphakheji zethala leencwadi ze-32-bit.
• В Kubuntu I-KDE Plasma 5.18 desktop, KDE Applications 19.12.3 kunye ne-Qt 5.12.5 framework ziyanikezelwa. Umdlali womculo ongagqibekanga nguElisa 19.12.3, othathe indawo yeCantata. I-latte-dock ehlaziyiweyo 0.9.10, KDEConnect 1.4.0, Krita 4.2.9, Kdevelop 5.5.0. Inkxaso ye KDE4 kunye ne Qt4 izicelo ziyekiwe.
  Iseshoni yovavanyo esekelwe kwi-Wayland iphakanyisiwe (emva kokufaka iphakheji ye-plasma-workspace-wayland, into ekhethwayo ethi "Plasma (Wayland)" ibonakala kwisikrini sokungena).
  

• Ubuntu MATE 20.04: MATE desktop ihlaziywe kuguqulelo 1.24. Yongezwe ujongano lohlaziyo lwe-firmware usebenzisa fwupd. ICompiz kunye neCompton zisusiwe kusasazo. Kubonelelwe ngomboniso wee-thumbnails zefestile kwiqela lenjongo, ujongano lokutshintsha umsebenzi (Alt-Tab) kunye nedesktop switcher. I-applet entsha yokubonisa izaziso iye yacetywa. I-Evolution isetyenziswa njengomthengi we-imeyile endaweni yeThunderbird. Xa ufaka abaqhubi be-NVIDIA abanini, abanokuthi bakhethwe kwi-installer, i-applet inikezelwa ukutshintsha phakathi kwe-GPU ezahlukeneyo kwiinkqubo ezinemizobo ye-hybrid (NVIDIA Optimus).
  

• Ubuntu Budgie: Ngokungagqibekanga, iapplet enemenu yesicelo yenziwe yasebenza ISylish kunye neapplet yayo yokulawula useto lwenethiwekhi.
  Ujongano olongeziweyo lokutshintsha ngokukhawuleza uyilo lwedesktop (Budgie, Ubuntu Budgie, Ubuntu Budgie, Cupertino, Lowo
  kunye neRedmond).
  Iphakheji ephambili ibandakanya i-GNOME Firmware kunye ne-GNOME Drawing applications.
  Ukudityaniswa okuphuculweyo kunye ne-GNOME 3.36. I-Budgie desktop ihlaziywe ukuba ibe yinguqulo 10.5.1. Iisetingi ezongeziweyo zochasa ukuchasa kunye nokuthantamisa kwefonti. Ngokungagqibekanga, iapplet yetreyi yesixokelelwano ivaliwe (ngenxa yeengxaki zokusebenza). IiApplets zilungiselelwe izikrini zeHiDPI.
  

• Ubuntu Studio: ULawulo lweSitudiyo se-Ubuntu lwahlula useto lweJack Master, izixhobo ezongezelelweyo kunye neengqimba zePulseAudio. I-RaySession ehlaziyiweyo 0.8.3, i-Audacity 2.3.3, iHydrogen 1.0.0-beta2, iCarla 2.1-RC2,
  I-Blender 2.82, KDEnlive 19.12.3, Krita 4.2.9, GIMP 2.10.18,
  Ardor 5.12.0, Scribus 1.5.5, Darktable 2.6.3, Pitivi 0.999, Inkscape 0.92.4, OBS Studio 25.0.3, MyPaint 2.0.0, Rawtherapee 5.8.

• В Xubuntu Ukuvela komxholo omnyama kwaphawulwa. IN Lubuntu Kuphela lutshintsho oluncinci kunye nohlaziyo olubonakalayo.
