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. Contemporaneamente \u00e8 stato rilasciato 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 struttura \"maybe \u2026 end\" per raggruppare pi\u00f9 espressioni all'interno di un unico blocco, simile a \"begin \u2026 end\", ma che non comporta l'esportazione delle variabili dal blocco.\n<li class=\"l\"> \u00c8 stata introdotta la supporto per l'attivazione selettiva delle funzionalit\u00e0, che consente di testare e implementare gradualmente nuove potenzialit\u00e0 del linguaggio e del runtime, potenzialmente incompatibili, senza compromettere il funzionamento del codice esistente. Le funzionalit\u00e0 possono essere attivate e disattivate sia durante la compilazione che tramite la direttiva feature() nei file di codice. Ad esempio, per attivare la nuova espressione maybe nel codice, si pu\u00f2 specificare \"feature(maybe_expr,enable)\".\n<li class=\"l\"> Nel compilatore JIT sono state implementate ottimizzazioni basate sulle informazioni sui tipi di dati e aggiunta il supporto per processori ARM a 64 bit (AArch64). Migliorato il supporto per gli strumenti perf e gdb, a cui \u00e8 stata garantita la trasmissione delle informazioni sui numeri di riga nel codice.\n<li class=\"l\"> Aggiunto un nuovo modulo peer con funzioni per avviare nodi Erlang connessi. Dopo la perdita della connessione di controllo con un nodo, il funzionamento del nodo viene automaticamente interrotto.\n<li class=\"l\"> Aggiunto il 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\"
