Kutulutsidwa kwa Ubuntu 21.04

Kutulutsidwa kwa Ubuntu 21.04 "Hirsute Hippo" kugawa kulipo, komwe kumatchedwa kutulutsidwa kwapakatikati, zosintha zomwe zimapangidwa mkati mwa miyezi 9 (thandizo lidzaperekedwa mpaka Januware 2022). Zithunzi zoyika zimapangidwira Ubuntu, Ubuntu Server, Lubuntu, Kubuntu, Ubuntu Mate, Ubuntu Budgie, Ubuntu Studio, Xubuntu ndi UbuntuKylin (Chinese edition).

Zosintha zazikulu:

• Desktop ikupitiliza kutumiza GNOME Shell 3.38, yomangidwa pogwiritsa ntchito GTK3, koma mapulogalamu a GNOME amalumikizidwa makamaka ndi GNOME 40 (kusintha kwa desktop kupita ku GTK 4 ndi GNOME 40 kumaonedwa kuti ndi nthawi isanakwane).
• Mwachikhazikitso, gawo lozikidwa pa protocol ya Wayland limayatsidwa.

• Thandizo lowonjezera la seva yapa media ya Pipewire, yomwe imakupatsani mwayi wokonza zojambulira pazenera, kukonza chithandizo chamawu pamapulogalamu akutali, perekani luso laukadaulo wamawu, chotsani kugawikana ndikugwirizanitsa zomvera pazogwiritsa ntchito zosiyanasiyana.
• Thandizo lowonjezera pakutsimikizira pogwiritsa ntchito makadi anzeru (pogwiritsa ntchito pam_sss 7).
• Pa desktop, kuthekera kosuntha zinthu kuchokera ku mapulogalamu pogwiritsa ntchito njira ya kukoka ndi kugwetsa yawonjezedwa.
• M'makonzedwe, tsopano ndi kotheka kusintha mbiri yogwiritsira ntchito mphamvu.
• Woyikirayo wawonjezera chithandizo chopangira makiyi osungira kuti abwezeretse mwayi wofikira magawo osungidwa, omwe angagwiritsidwe ntchito polemba ngati mawu achinsinsi atayika.
• Kuphatikizana bwino ndi Active Directory komanso kuthekera kotsimikizira ogwiritsa ntchito mu Active Directory ndi thandizo la GPO (Group Policy Objects) mutangokhazikitsa Ubuntu.

GPO itha kugwiritsidwa ntchito kufotokozera mfundo zachitetezo kwa makasitomala onse olumikizidwa, kuphatikiza kukhazikitsa magawo ofikira ogwiritsa ntchito ndi malamulo achinsinsi.
• Njira yopezera maupangiri akunyumba ya ogwiritsa ntchito yasinthidwa - zolemba zakunyumba tsopano zapangidwa ndi ufulu 750 (drwxr-x—), zomwe zimapereka mwayi wopeza chikwatu kwa eni ake ndi mamembala a gulu okha. Pazifukwa zakale, zolemba zakale za ogwiritsa ntchito ku Ubuntu zidapangidwa ndi zilolezo 755 (drwxr-xr-x), kulola wogwiritsa ntchito wina kuwona zomwe zili mu bukhu la wina.
• Linux kernel yasinthidwa kukhala mtundu wa 5.11, womwe umaphatikizapo kuthandizira kwa Intel SGX enclaves, njira yatsopano yolumikizira mafoni amtundu, mabasi othandizira, kuletsa ma module omanga opanda MODULE_LICENSE (), njira yosefera mwachangu pama foni amtundu wa seccomp. , kuthetsedwa kwa chithandizo cha zomangamanga za ia64, kusamutsidwa kwa teknoloji ya WiMAX ku nthambi ya "staging", kutha kuyika SCTP mu UDP.
• Mwachikhazikitso, fyuluta ya paketi ya nftables imayatsidwa. Kuti musunge kuyanjana kwa m'mbuyo, phukusi la iptables-nft likupezeka, lomwe limapereka zothandizira ndi mzere wofanana wa malamulo monga iptables, koma amamasulira malamulowo kukhala nf_tables bytecode.
