Sproget har fundet anvendelse i omr\u00e5der som telekommunikation, banksystemer, e-handel, computertelefoni og organisation af \u00f8jeblikkelig messaging. Samtidig blev OTP 25 (Open Telecom Platform) udgivet \u2014 et tilsvarende s\u00e6t biblioteker og komponenter til udvikling af distribuerede systemer p\u00e5 Erlang-sproget.       <\/p>\n<p>Hovednyhederne:  <\/p>\n<ul>\n<li class=\"l\"> Der er implementeret en ny konstruktion \u00abmaybe \u2026 end\u00bb til gruppering af flere udtryk i \u00e9n blok, som ligner \u00abbegin \u2026 end\u00bb, men som ikke medf\u00f8rer eksport af variabler fra blokken.\n<li class=\"l\"> Der er tilf\u00f8jet st\u00f8tte til selektiv aktivering af funktioner, hvilket g\u00f8r det muligt at teste og gradvist implementere nye og potentielt bagudkompatibilitetsneds\u00e6ttende funktioner i sproget og runtime uden at p\u00e5virke eksisterende kode. Funktioner kan aktiveres og deaktiveres b\u00e5de under kompilering og ved hj\u00e6lp af direktivet feature() i kodefiler. For eksempel kan det nye udtryk maybe inkluderes i koden ved at angive \u00abfeature(maybe_expr,enable)\u00bb.\n<li class=\"l\"> Der er implementeret optimeringer baseret p\u00e5 information om datatyper i JIT-kompilatoren, og der er tilf\u00f8jet st\u00f8tte til 64-bit ARM-processorer (AArch64). St\u00f8tten til v\u00e6rkt\u00f8jerne perf og gdb er forbedret, hvor linjenumre i koden nu overf\u00f8res.\n<li class=\"l\"> Der er tilf\u00f8jet en ny peer modul med funktioner til at starte tilknyttede Erlang noder. Efter tab af kontrolforbindelse til en node afsluttes nodens drift automatisk.\n<li class=\"l\"> St\u00f8tte til OpenSSL 3.0 er blevet tilf\u00f8jet.\n<li class=\"l\"> I modulet maps er der tilf\u00f8jet funktionerne groups_from_list\/2 og groups_from_list\/3 til gruppering af en liste af elementer.\n<li class=\"l\"> I modulet lists er der tilf\u00f8jet funktionerne uniq\/1, uniq\/2, enumerate\/1 og enumerate\/2 til filtrering af duplikerede elementer i en liste og generering af en liste af tupler med elementernes numre.\n<li class=\"l\"> I modulet rand er der implementeret en ny,
