Rammev\u00e6rket giver udvikleren et fleksibelt v\u00e6rkt\u00f8j fra Erlangs verden til at skabe distribuerede l\u00f8sninger i Go ved hj\u00e6lp af f\u00e6rdige designm\u00f8nstre som Application, Supervisor og GenServer. Da Go-sproget ikke har en direkte analog til Erlang-processen, anvendes goroutines i rammev\u00e6rket som basis for GenServer med en recover-wrapper for mulighed for h\u00e5ndtering af undtagelsessituationer. Projektets kode distribueres under MIT-licensen.    <\/p>\n<p>I den nye version:  <\/p>\n<ul>\n<li class=\"l\"> Underst\u00f8ttelsen af TLS 1.3 er blevet implementeret med mulighed for automatisk at generere selvsignerede certifikater (hvis det er n\u00f8dvendigt at kryptere forbindelser, men der ikke er behov for autorisation, da forbindelsen bruger cookies til at give adgang til noden).\n<li class=\"l\"> Statisk routing er blevet tilf\u00f8jet for at udelukke anmodninger til EPMD for at bestemme nodens port. Dette l\u00f8ser sikkerhedsproblemet og giver mulighed for at k\u00f8re en Erlang-kluster p\u00e5 offentlige netv\u00e6rk sammen med kryptering.\n<li class=\"l\"> Der er tilf\u00f8jet en ny GenStage-skabelon (fra Elixir-verdenen), der muligg\u00f8r oprettelse af Pub\/Sub-l\u00f8sninger uden brug af Message Bus. En af de vigtige funktioner ved denne skabelon er \"backpressure control\". \"Producer\" vil levere pr\u00e6cist det antal meddelelser, der er anmodet af \"Consumer.\" Et eksempel p\u00e5 implementering kan ses her.   <\/ul>\n<p>I diskussionsafsnittet diskuteres implementeringen af designm\u00f8nsteret SAGAS, som implementerer funktionaliteten af distribuerede transaktioner.<br
