NgoJuni 17, 2019, kwethulwa ukukhishwa okulandelayo okubalulekile kohlelo lokusebenza lwe-DragonFly BSD - Release56. Ukukhishwa kuletha intuthuko ebalulekile ku-Virtual Memory System, izibuyekezo ku-Radeon ne-TTM, kanye nokuthuthukiswa kokusebenza ku-HAMMER2.
I-DragonFly yasungulwa ngo-2003 njengemfoloko evela ku-FreeBSD version 4. Phakathi kwezici eziningi zaleli gumbi lokuhlinza, okulandelayo kungagqanyiswa:
-
Uhlelo lwefayela olusebenza kahle kakhulu HAMMER2 - ukusekelwa kokubhalela izifinyezo eziningi ngokuhambisana, uhlelo lwe-quota oluguquguqukayo (kuhlanganise nezinkomba), isibuko esikhulayo, ukucindezela okusekelwe kuma-algorithms ahlukahlukene, i-multi-master mirroring esatshalaliswe. Indlela yokuhlanganisa isakhiwa.
-
I-hybrid kernel esekelwe kuchungechunge olungasindi olunamandla okusebenzisa amakhophi amaningi e-kernel njengezinqubo zesikhala somsebenzisi.
Izinguquko Ezinkulu Zokukhishwa
-
Izinguquko eziningi zenziwe ohlelweni olungaphansi lwememori ebonakalayo, olukhulise kakhulu ukusebenza, lwafika ku-40-70% ezinhlotsheni ezithile zokusebenza.
-
Izinguquko eziningi kumshayeli we-DRM we-Radeon kanye nesistimu engaphansi yokulawulwa kwememori yevidiyo ye-TTM yama-chip evidiyo e-AMD.
-
Ukusebenza okuthuthukisiwe kohlelo lwefayela le-HAMMER2.
-
Kwengezwe ukusekelwa kwe-FUSE esikhaleni somsebenzisi.
-
Kusetshenziswe ukuhlukaniswa kwedatha ku-CPU phakathi kwesistimu nomsebenzisi: I-SMAP (Ukuvimbela Ukufinyelela Kwemodi Yomphathi) kanye ne-SMEP (Ukuvimbela Ukwenziwa Kwemodi Yomphathi). Ukuze uzisebenzise, usekelo oluvela ku-CPU luyadingeka.
-
Kuma-Intel processors, ukuvikelwa kusigaba sokuhlasela se-MDS (Microarchitectural Data Sampling) kuyasetshenziswa. Ikhutshaziwe ngokuzenzakalelayo futhi kufanele inikwe amandla mathupha. Ukuvikelwa kwe-Specter kunikwe amandla ngokuzenzakalela.
-
Ukuthuthela ku-LibreSSL kuyaqhubeka.
-
Izinguqulo ezibuyekeziwe zezingxenye ze-OS zenkampani yangaphandle.
