Ngemuva kwesikhathi esifushane sokuhlola i-beta, i-Canonical isanda kumemezela ukukhishwa kwenguqulo entsha ye -Ubuntu Linux 24.04 LTS, ebizwa ngokuthi "i-Noble Numbat," enezici eziningi ezibalulekile kanye nentuthuko.
I-Ubuntu 24.04 LTS , njengenguqulo yokusekela yesikhathi eside, inikeza ukwesekwa okufika eminyakeni eyi-12 kulabo abakhetha i-Ubuntu Pro, kuyilapho inguqulo ejwayelekile ye-Ubuntu 24.04 ineminyaka emihlanu yokugcinwa kokuphepha ngqo endaweni yokugcina eyinhloko ye-Ubuntu.
Yini entsha ku-Ubuntu 24.04 LTS “Noble Numbat”?
I-Ubuntu 24.04 LTS iza ne- Linux 6.8 kernel enokusebenza okuthuthukisiwe kocingo lwesistimu, ukwesekwa kwe-KVM okufakwe ku-ppc64el, kanye nokufinyelela ohlelweni olusha lwamafayela e-beachefs.
Ngasohlangothini lwedeskithophu, i-GNOME 46 iyindawo yedeskithophu ezenzakalelayo. Le nguqulo iletha ukuthuthukiswa okuningana ezinhlelweni zokuphathwa kwamafayela, ikakhulukazi i-Nautilus, manje ene-interface yomsebenzisi eklanywe kabusha kanye nomsebenzi wokusesha womhlaba wonke othuthukisiwe. Ngaphezu kwalokho, i-GNOME 46 ifaka izibuyekezo kuhlelo lokusebenza lwezilungiselelo, ukwesekwa kwezaziso ezinwebekayo, uhlelo lwe-akhawunti olusetshenzwe kabusha ku-inthanethi, kanye nezaziso ezithuthukisiwe.
I-NetworkManager manje isebenzisa i-Netplan njenge-backend yakho yokumisa okuzenzakalelayo. Uma uthuthukisa, wonke amaphrofayili okuxhumana /etc/NetworkManager/system-connections/ athuthelwe ngokusobala ukuya /etc/netplan/90-NM-*.yaml futhi ube amaphrofayili okuxhumana anikezwe i-Netplan in /run/NetworkManager/system-connections/.
Kwethulwe isitolo esisha sohlelo lokusebenza , esithatha indawo yesitolo sangaphambilini se-Snap. Uhlelo lokusebenza lwabhalwa kusukela ekuqaleni kusetshenziswa ithuluzi le-Flutter. Isitolo esisha senzelwe ukusingatha kokubili izinhlelo zokusebenza ze-.deb kanye ne-snap (njalo sibeka phambili i-snap).
Kuye kwethulwa nesifaki esisha esisekelwe ku-Flutter , esinenqubo ezenzakalelayo yokufaka kusetshenziswa ifayela lokucushwa kwe-.yaml (lendawo noma elikude). Isifaki siphinde sathuthukiswa ngokubonakalayo ngemifanekiso emisha, ebamba amehlo yesinyathelo ngasinye kanye nezincazelo zombhalo ezicacile nezimfushane. Izinketho zokufinyeleleka zengezwe njengesinyathelo sesibili, futhi ukwesekwa kokufakwa okuqondiswe yi-ZFS (okuthuthukisiwe) kuye kwaphinde kwethulwa.
Okunye okuphawulekayo ukusekelwa kwe-.NET 8 okugcwele kulokhu kukhishwa kwe-LTS , kanye ne-Java LTS eqinisekiswe yi-TCK ye-.NET. Lokhu kukhishwa kunezela namathuluzi abuyekeziwe, kufaka phakathi i-Python 3.12, i-Ruby 3.2, i-PHP 8.3, kanye ne-Go 1.22.
Amathuluzi amasha okuphatha aqaliswe ku-Ubuntu Desktop kanye ne-Windows Subsystem ye-Linux (WSL), kusetshenziswa ubuchwepheshe bokufaka okwabelwana ngabo ukuvumela ukwenza ngezifiso izithombe ngamathuluzi anjengokufaka okuzenzakalelayo kanye ne-cloud-init.
Ngaphezu kwalokho, i-Ubuntu 24.04 LTS igxile ekuthuthukiseni ukuphepha ngezinyathelo ezahlukahlukene. Enye yalezi ukuvinjelwa kwezikhala zamagama zomsebenzisi ezingenamalungelo . Kule nguqulo, ukufinyelela izimvume ezengeziwe ngaphakathi kwalezi zikhala zamagama kunqunyelwe, ngaleyo ndlela kunciphisa izindawo zokuhlasela ezingaba khona.
Kuyafaneleka futhi ukuqaphela ukuthi i-FORTIFY_SOURCE iphakanyiswe yaya ezingeni lesi-3, okuthuthukisa ukutholakala kokwephulwa kokuphepha kwememori emisebenzini evamile njenge-memcpy() kanye ne-snprintf(). Ku-architecture ye-ARM64, izinyathelo ezifana nokuqinisekiswa kwe-pointer okuphoqelelwe yihadiwe kanye nokuhlonza i-branch target kwasetshenziswa ukunciphisa ukuhlaselwa kokusetshenziswa kabusha kwekhodi.
I-AppArmor iphinde yabuyekezwa yaba yinguqulo 4.0 , yethula ukuthuthukiswa okuningana ekulawulweni kokufinyelela kwenethiwekhi, izinqubomgomo ezinemibandela eziyinkimbinkimbi, kanye nekhono lokuhlehlisa izinqumo zokufinyelela ezinhlelweni zomsebenzisi-isikhala. Lokhu kuvumela amamodeli okuphepha athuthukile, njengezicelo zokufinyelela amafayela ezisebenzisanayo.
Ngokuphathelene nokuphepha kwephrothokholi ye-cryptographic, i-Ubuntu 24.04 ikhubaza izinguqulo eziphelelwe yisikhathi nezingavikelekile ze-TLS (1.0 kanye ne-1.1) kanye ne-DTLS 1.0 ukuvimbela ukuhlaselwa kokuwohloka okungadalula idatha ebucayi. Lezi zinyathelo zinegalelo elikhulu ekuthuthukiseni ukuphepha okuphelele kwesistimu yokusebenza.
Ezinye izinguquko eziphawulekayo zifaka:
- I-System init ibuyekezelwe ku-systemd 255.4
- Isitaki senethiwekhi sibuyekezelwe ku-Netplan 1.0 162 ngosekelo lwe-WPA2 kanye ne-WPA3 ngasikhathi sinye, i-Mellanox VF-LAG yenethiwekhi ye-SR-IOV esebenza kahle kakhulu, nezithuthukisi ze-VXLAN.
- i-openssh ayisancikile ku-libsystemd, inciphisa inani lokuncika futhi iyenze ingathambekele kangako ezindabeni zokuphepha zesikhathi esizayo.
- Ithuluzi lokuvuselela elibizwa ngokuthi I-Firmware Updater ukuze ubuyekeze i-firmware kahle ngaphandle kokusebenzisa umphathi ogcwele wohlelo ngemuva.
- Ukusekelwa kwesisheshisi se-QAT esakhelwe kuma-Intel processors, sihlinzeka ngamathuluzi okusheshisa izibalo ezisetshenziswa ekucindezelweni nasekubetheleni.
- Amaphakheji aguquliwe okwakhiwa kwe-32-bit Armhf ukuze asebenzise uhlobo lwe-64-bit time_t ukuphatha izikhathi ezingemuva komhla ka-19 Januwari 2038.
