Den nye version underst\u00f8tter Linux-kerner fra 3.10 og FreeBSD fra version 12.2, og derudover samler den nu koden for begge operativsystemer i et enkelt depot. Blandt de mest markante \u00e6ndringer bem\u00e6rker udviklerne f\u00f8lgende:<\/p>\n<ul>\n<li>\n<p>Der er tilf\u00f8jet en mulighed for sekventiel (LBA) rekonstruktion af en \u00f8delagt RAID-mirror vDev. Denne mekanisme er meget hurtigere end den traditionelle \"helende\" reparation. Dog mangler der kontrolsumvalidering af blokke, hvorfor systemintegritetskontrollen (scrub) straks efter afslutningen af denne proces startes.<\/p>\n<\/li>\n<li>\n<p>Genoprettelse af L2ARC-cachedata efter systemgenstart. Cachen bruger en dedikeret m\u00e6ngde RAM uden at involvere den langsommere harddisk ved hyppige dataanmodninger. Nu vil L2ARC-cachedataene v\u00e6re p\u00e5 plads efter genstart.<\/p>\n<\/li>\n<li>\n<p>Underst\u00f8ttelse af kompression i ZStandard-format, der giver et kompressionsniveau sammenligneligt med GZIP, men med betydeligt h\u00f8jere ydeevne. For administratorens bekvemmelighed er der mulighed for at v\u00e6lge kompressionsniveauet for at sikre den bedste balance mellem hastighed og pladseffektivitet.<\/p>\n<\/li>\n<li>\n<p>Mulighed for at v\u00e6lge data ved overf\u00f8rsel med send\/receive-kommandoerne. Nu kan administratorer manuelt udelukke un\u00f8dvendige eller private data fra overf\u00f8rslen f\u00f8r kopiering af snapshot.<\/p>\n<\/li>\n<li>\n<noindex><noindex><\/p>\n<p>Mange andre, mindre, men ikke mindre behagelige forbedringer er blevet implementeret, herunder udviklingen af en pam-modul til indl\u00e6sning af krypteringsn\u00f8gler til mapper, omorganisering af man-sider og <a
