St\u00f6d finns f\u00f6r alla obligatoriska gr\u00e4nssnitt i C99 och POSIX 2008, samt delvis f\u00f6r C11 och en upps\u00e4ttning f\u00f6r utvidgningar f\u00f6r flertr\u00e5dprogrammering (POSIX-tr\u00e5dar), minneshantering och arbete med lokaler. Musl-koden distribueras under den fria MIT-licensen.     <\/p>\n<p>Den nya versionen introducerar funktionen qsort_r, som \u00e4r avsedd att inkluderas i framtida POSIX-standarder och anv\u00e4nds f\u00f6r att sortera arrayer med godtyckliga j\u00e4mf\u00f6relsefunktioner. St\u00f6d f\u00f6r alternativa SPE FPU (Signal Processing Engine) har lagts till f\u00f6r vissa modeller av PowerPC CPU. \u00c4ndringar har gjorts f\u00f6r att f\u00f6rb\u00e4ttra kompatibiliteten, exempelvis relaterat till bevarande av errno-v\u00e4rdet, acceptera nullpekare i gettext och hantering av milj\u00f6variabeln TZ. Regresjoner i funktionerna wcwidth och duplocale har \u00e5tg\u00e4rdats, liksom flera fel i matematiska funktioner som under vissa omst\u00e4ndigheter ledde till felaktiga resultat (till exempel avrundades resultatet felaktigt i fmaf p\u00e5 system utan FPU).      <\/p>\n<p>Dessutom kan vi n\u00e4mna det nyligen sl\u00e4ppta standard C-biblioteket PicoLibc 1.7.6, utvecklat av Keith Packard (projektledare f\u00f6r X.Org) f\u00f6r anv\u00e4ndning p\u00e5 inbyggda enheter med begr\u00e4nsat permanent lagringsutrymme och RAM. Under utvecklingen har en del av koden l\u00e5nats fr\u00e5n newlib-biblioteket fr\u00e5n Cygwin-projektet och AVR Libc, som utvecklades f\u00f6r Atmel AVR mikrocontrollers. PicoLibc-koden distribueras under BSD-licensen. Biblioteket st\u00f6der kompilering f\u00f6r ARM (32-bit), Aarch64, i386, RISC-V, x86_64, m68k och PowerPC-arkitekturer. I den nya versionen har till\u00e4mpningen av matematiska inline-funktioner f\u00f6r aarch64-arkitekturen och m\u00f6jligheten att anv\u00e4nda matematiska inline-funktioner i applikationer p\u00e5
