Pa Juni 17, 2019, kutulutsidwa kofunikira kotsatira kwa kachitidwe ka DragonFly BSD - Release56 - kunaperekedwa. Kutulutsidwa 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 kuchokera ku mtundu wa 4 wa FreeBSD. Zina mwazinthu zambiri za chipinda chopangira opaleshonichi, zotsatirazi zitha kuwunikira:
-
Fayilo yochita bwino kwambiri HAMMER2 - chithandizo cholembera zithunzi zingapo mofananira, kachitidwe kosinthika kachulukidwe (kuphatikiza maulalo), magalasi owonjezera, kuponderezana kutengera ma aligorivimu osiyanasiyana, kugawa magalasi amitundu yambiri. Makina ophatikizana akukonzedwa.
-
Kernel yosakanizidwa yotengera ulusi wopepuka wokhala ndi kuthekera koyendetsa makope angapo a kernel ngati njira zogwiritsira ntchito malo.
Zosintha Zazikulu Zotulutsidwa
-
Zosintha zambiri zapangidwa kuzinthu zokumbukira, zomwe zachulukitsa kwambiri magwiridwe antchito, mpaka 40-70% pamitundu ina ya ntchito.
-
Zosintha zambiri kwa oyendetsa DRM a Radeon ndi kasamalidwe ka vidiyo ya TTM kasamalidwe ka tchipisi ta AMD.
-
Kuchita bwino kwa fayilo ya HAMMER2.
-
Thandizo lowonjezera la FUSE mu malo ogwiritsa ntchito.
-
Kukhazikitsa kudzipatula kwa data mu CPU pakati pa makina ndi wogwiritsa ntchito: SMAP (Supervisor Mode Access Prevention) ndi SMEP (Supervisor Mode Execution Prevention). Kuti mugwiritse ntchito, chithandizo chochokera ku CPU chimafunika.
-
Kwa ma processor a Intel, chitetezo ku gulu la MDS (Microarchitectural Data Sampling) chimakhazikitsidwa. Imayimitsidwa mwachisawawa ndipo iyenera kuyatsidwa pamanja. Chitetezo cha Specter chimayatsidwa ndi kusakhazikika.
-
Kusamukira ku LibreSSL kukupitilira.
-
Zosinthidwa za zigawo za OS za chipani chachitatu.
