Il linguaggio ha trovato applicazione in settori come le telecomunicazioni, i sistemi bancari, il commercio elettronico, la telefonia computerizzata e la gestione della messaggistica istantanea. \u00c8 stato rilasciato contemporaneamente anche OTP 25 (Open Telecom Platform) \u2014 un insieme complementare di librerie e componenti per lo sviluppo di sistemi distribuiti con il linguaggio Erlang.       <\/p>\n<p>Novit\u00e0 principali:  <\/p>\n<ul>\n<li class=\"l\"> \u00c8 stata implementata una nuova costrutto \u00abmaybe \u2026 end\u00bb per raggruppare pi\u00f9 espressioni in un unico blocco, simile a \u00abbegin \u2026 end\u00bb, ma non causa l'esportazione delle variabili dal blocco.\n<li class=\"l\"> \u00c8 stata aggiunta la supporto per l'attivazione selettiva delle funzionalit\u00e0, che consente di testare e implementare gradualmente nuove e potenzialmente incompatibili funzionalit\u00e0 del linguaggio e del runtime senza interrompere il funzionamento del codice esistente. Le funzionalit\u00e0 possono essere attivate o disattivate sia durante la compilazione, sia tramite la direttiva feature() nei file di codice. Ad esempio, per abilitare la nuova espressione maybe nel codice, si pu\u00f2 indicare \u00abfeature(maybe_expr,enable)\u00bb.\n<li class=\"l\"> Nel compilatore JIT sono state realizzate ottimizzazioni basate su informazioni sui tipi di dati e \u00e8 stata aggiunta la supporto per processori ARM a 64 bit (AArch64). \u00c8 stata migliorata la supporto per gli strumenti perf e gdb, con la trasmissione delle informazioni sui numeri di riga nel codice.\n<li class=\"l\"> \u00c8 stato aggiunto un nuovo modulo peer con funzioni per avviare nodi Erlang collegati. Dopo la perdita della connessione di controllo con il nodo, il funzionamento del nodo viene automaticamente interrotto.\n<li class=\"l\"> \u00c8 stata aggiunta la supporto per OpenSSL 3.0.\n<li class=\"l\"> Nel modulo maps sono state aggiunte le funzioni groups_from_list\/2 e groups_from_list\/3 per raggruppare un elenco di elementi.\n<li class=\"l\"> Nel modulo lists sono state aggiunte le funzioni uniq\/1, uniq\/2, enumerate\/1 e enumerate\/2 per filtrare gli elementi duplicati in un elenco e generare un elenco di tuple con i numeri degli elementi.\n<li class=\"l\"> Nel modulo rand \u00e8 stato implementato un nuovo generatore di numeri pseudocasuali molto veloce.      <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
