Pa Juni 17, 2019, kutulutsidwa kwakukulu kotsatira kwa makina opangira a DragonFly BSD, Release 56, adatulutsidwa. Kutulutsidwa kumeneku kumabweretsa kusintha kwakukulu kwa Virtual Memory System, zosintha za Radeon ndi TTM, komanso kusintha kwa magwiridwe antchito ku HAMMER2.
DragonFly idapangidwa mu 2003 ngati foloko ya mtundu 4 wa FreeBSD. Zina mwazinthu zambiri zamakina opangira izi, zotsatirazi ndizodziwika bwino:
Makina apamwamba kwambiri a HAMMER2 amafayilo amathandizira kulembera zithunzi zingapo mofananira, kachitidwe kosinthika kachulukidwe (kuphatikiza ma quotas), magalasi owonjezera, kuponderezana kutengera ma algorithms osiyanasiyana, ndikugawa magalasi ambiri. Njira yophatikizira pagulu ikukonzedwa.
Kernel yosakanizidwa yotengera ulusi wopepuka wokhala ndi kuthekera koyendetsa makope angapo a kernel ngati njira mu malo ogwiritsa ntchito.
Kusintha kofunikira
Zosintha zambiri zapangidwa kuzinthu zokumbukira, zomwe zachulukitsa magwiridwe antchito, mpaka 40-70% pamitundu ina ya ntchito.
Zosintha zambiri pa driver wa Radeon DRM ndi kasamalidwe ka mavidiyo a TTM a AMD GPU.
Kuchita bwino kwa fayilo ya HAMMER2.
Adawonjezera thandizo la FUSE mu malo ogwiritsa ntchito.
Kupatula kwa data pakati pa makina ndi wogwiritsa ntchito kwakhazikitsidwa mu CPU: SMAP (Supervisor Mode Access Prevention) ndi SMEP (Supervisor Mode Execution Prevention). Thandizo lochokera ku CPU likufunika kuti izi zitheke.
Ma processor a Intel akhazikitsa chitetezo ku gulu lankhondo la MDS (Microarchitectural Data Sampling). Chitetezo ichi chimayimitsidwa mwachisawawa ndipo chiyenera kuyatsidwa pamanja. Chitetezo cha Specter chimayatsidwa ndi kusakhazikika.
Kusamukira ku LibreSSL kukupitilira.
Mabaibulo a chipani chachitatu cha OS asinthidwa.
