A nova vers\u00e3o suporta n\u00facleos Linux a partir da vers\u00e3o 3.10 e FreeBSD a partir da vers\u00e3o 12.2, al\u00e9m de agora unir o c\u00f3digo para ambos os sistemas operacionais em um \u00fanico reposit\u00f3rio. Entre as principais mudan\u00e7as, os desenvolvedores destacam as seguintes:<\/p>\n<ul>\n<li>\n<p>Foi adicionada a capacidade de reconstruir sequencialmente (LBA) um array RAID Mirror vDev danificado.

Para conveni\u00eancia, o administrador tem a op\u00e7\u00e3o de escolher o n\u00edvel de compress\u00e3o para garantir o melhor equil\u00edbrio entre desempenho e economia de espa\u00e7o em disco.<\/p>\n<\/li>\n<li>\n<p>Capacidade de sele\u00e7\u00e3o de dados ao transferir com os comandos send\/receive.
