Il framework fornisce agli sviluppatori strumenti flessibili dal mondo di Erlang per creare soluzioni distribuite in Go utilizzando modelli di design pronti come Application, Supervisor e GenServer. Poich\u00e9 in Go non esiste un analogo diretto del processo Erlang, il framework utilizza goroutine come base per GenServer con un wrapper recover per gestire le eccezioni. Il codice del progetto \u00e8 distribuito sotto licenza MIT.    <\/p>\n<p>Nel nuovo rilascio:  <\/p>\n<ul>\n<li class=\"l\"> \u00c8 stata implementata la supporto per TLS 1.3 con la possibilit\u00e0 di generare automaticamente certificati autofirmati (se \u00e8 necessario crittografare le connessioni, ma non \u00e8 necessaria l'autenticazione, poich\u00e9 la connessione utilizza i cookie per fornire accesso al nodo).\n<li class=\"l\"> \u00c8 stata aggiunta la routing statica, per evitare di dover contattare EPMD per determinare la porta del nodo. Questo risolve problemi di sicurezza e, insieme alla crittografia, consente di avviare un cluster Erlang su reti pubbliche.\n<li class=\"l\"> \u00c8 stato aggiunto un nuovo modello GenStage (dal mondo di Elixir), che consente di creare soluzioni Pub\/Sub senza utilizzare un Message Bus. Una delle caratteristiche importanti di questo modello \u00e8 il \u00abcontrollo del backpressure\u00bb. Il \u00abProduttore\u00bb consegner\u00e0 esattamente il volume di messaggi richiesto dal \u00abConsumatore\u00bb. Un esempio di implementazione pu\u00f2 essere visualizzato qui.   <\/ul>\n<p>Nella sezione delle discussioni si parla dell'implementazione del pattern di design SAGAS, che realizza la
