Den grundl\u00e6ggende desktop-milj\u00f8 er bygget p\u00e5 Xfce (det er muligt at installere en kombination af GNUstep + Window Maker + GWorkspace). I mods\u00e6tning til andre desktop-samlinger af FreeBSD er MidnightBSD oprindeligt blevet udviklet som en fork af FreeBSD 6.1-beta, som i 2011 blev synkroniseret med koden fra FreeBSD 7 og senere inkorporerede mange funktioner fra brancherne FreeBSD 9-13. Til pakkeh\u00e5ndtering i MidnightBSD anvendes systemet mport, som benytter en SQLite-database til lagring af indekser og metadata, eller v\u00e6rkt\u00f8jet Ravenports. For installation er der forberedt et installationsbillede p\u00e5 1 GB (i386, amd64).          <\/p>\n<p>Udgivelsen er bem\u00e6rkelsesv\u00e6rdig p\u00e5 grund af opdateringen af versioner af tredjepartsbiblioteker og overf\u00f8rslen af rettelser og nye funktioner fra brancherne FreeBSD 13. De vigtigste nyheder:  <\/p>\n<ul>\n<li class=\"l\"> Pakkemanagementsystemet mport er blevet opdateret til version 2.7.3, hvor det nu er muligt at kontrollere individuelle porte med kommandoen &#171;mport verify&#187; og genoprette kontrolsummer med kommandoen &#171;mport verify -r&#187;. I kommandoen mport_install er der sikret funktionalitet med hensyn til afh\u00e6ngigheder.\n<li class=\"l\"> I programmerne init, service og cron er der valgt milj\u00f8variabler, som er angivet for brugeren eller brugergruppen gennem login.conf.\n<li class=\"l\"> Der er tilf\u00f8jet support til hukommelsesmapping i W^X-tilstand i kernen, som forhindrer samtidig skrive- og eksekveringsadgang.\n<li class=\"l\"> I stedet for GNU grep er der anvendt en variant af v\u00e6rkt\u00f8jet grep under BSD-licensen.\n<li class=\"l\"> Der er tilf\u00f8jet et Linux-kompatibelt systemopkald copy_file_range samt systemopkald aio_readv og aio_writev.\n<li class=\"l\"> Der er tilf\u00f8jet support til procesfejlfinding ved hj\u00e6lp af procfs.\n<li class=\"l\"> Der er tilf\u00f8jet en backlight-driver til kontrol af baggrundsbelysningen.\n<li class=\"l\"> I cpufreq-driveren er der implementeret support til Intel Speed Shift-teknologi.\n<li class=\"l\"> I klienten og <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/dts-newyork\/\"   title=\"serveren\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2840\">serveren<\/a> NFS er der tilf\u00f8jet st\u00f8tte til NFSv4.2, NFS over TLS og udvidede attributter.\n<li class=\"l\"> Overgangen til implementeringen af ZFS-filsystemet fra projektet OpenZFS (2.1.15) er gennemf\u00f8rt.\n<li class=\"l\"> Implementeringen af FUSE-systemet er blevet opdateret til version 7.28 med support for FUSE_COPY_FILE_RANGE og FUSE_LSEEK.\n<li class=\"l\"> TCP-stakken har f\u00e5et integreret st\u00f8tte til algoritmen for proportional reduktion af pakkeafsendelsesintensitet (Proportional Rate Reduction, RFC 6937), som g\u00f8r det muligt hurtigere at genoprette optimale str\u00f8mparametre efter midlertidige problemer med datatransmission.\n<li class=\"l\"> Der er tilf\u00f8jet st\u00f8tte til indlejrede VLAN (802.1ad).\n<li class=\"l\"> SCTP-protokollen er flyttet til en separat modul sctp.ko, som som standard er deaktiveret i GENERIC-kernen.\n<li class=\"l\"> Rute-s\u00f8gealgoritmer fra DPDK (Data Plane Development Kit) librte er tilf\u00f8jet for at optimere h\u00e5ndteringen af meget store routingtabeller.\n<li class=\"l\"> P\u00e5 64-bit arkitekturer er basissystemet som standard bygget med st\u00f8tte for PAE (Position Independent Executable).\n<li class=\"l\"> iwlwifi-driveren til Intel tr\u00e5dl\u00f8se kort er tilf\u00f8jet med st\u00f8tte for nye chips og standarden 802.11ac. Driveren er baseret p\u00e5 Linux-driveren og koden fra Linux-netv\u00e6rkssystemet net80211, hvis funktioner i FreeBSD st\u00f8ttes af en linuxkpi-lag.\n<li class=\"l\"> For alle eksekverbare filer i basissystemet p\u00e5 64-bit platforme er address randomization (ASLR, Address Space Layout Randomization) som standard aktiveret.\n<li class=\"l\"> Underst\u00f8ttelse af Netlink kommunikationsprotokollen (RFC 3549), der anvendes i Linux til at organisere interaktionen mellem kernen og brugerprocesser, er implementeret.\n<li class=\"l\"> Hypervisoren Bhyve har f\u00e5et tilf\u00f8jet st\u00f8tte til f\u00e6lles filadgang via VirtIO-9p (VirtFS), underst\u00f8ttelse af PCI HDAudio-enheder samt mulighed for at arbejde med snapshots. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/vps\/\"   title=\"virtual machines\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2249\">virtual machines<\/a>.\n<li class=\"l\"> Et s\u00e6t VirtIO-drivere, der underst\u00f8tter VirtIO V1 specifikationen, er tilf\u00f8jet.
