I den parallelt underst\u00f8ttede stabile gren 1.24.x foretages der kun \u00e6ndringer relateret til udbedring af alvorlige fejl og s\u00e5rbarheder. Fremadrettet vil der p\u00e5 grundlag af den prim\u00e6re gren 1.25.x blive dannet en stabil gren 1.26. Projektkoden er skrevet i C og distribueres under BSD-licensen.       <\/p>\n<p>Blandt \u00e6ndringerne:  <\/p>\n<ul>\n<li class=\"l\"> Forst\u00e6rket beskyttelse mod unormal aktivitet fra HTTP\/2-klienter, is\u00e6r mod DoS-angreb af typen \u00abRapid Reset\u00bb, hvor der oprettes et stort antal omg\u00e5ende nulstillede streams inden for en enkelt HTTP\/2-forbindelse. I standardkonfigurationen rammer s\u00e5danne angreb gr\u00e6nsen for antallet af foresp\u00f8rgsler pr. forbindelse \u00abkeepalive_requests\u00bb (efter hver 1000 foresp\u00f8rgsler vil forbindelsen blive nulstillet) og restriktionerne \u00ablimit_req\u00bb. For at reagere hurtigere p\u00e5 flodf\u00e6nomener med foresp\u00f8rgsler gennem et stort antal streams er der tilf\u00f8jet en ekstra gr\u00e6nse, som ikke tillader at oprette mere end 256 (2 * max_concurrent_streams) nye streams pr. eventsbehandlingscyklus som standard. Denne nye begr\u00e6nsning muligg\u00f8r, at anmodninger kan begynde at blive blokeret, f\u00f8r den samlede gr\u00e6nse for antal samtidige streams n\u00e5s, f.eks. n\u00e5r streams behandles asynkront eller nulstilles. En lignende \u00e6ndring er ogs\u00e5 blevet inkluderet i udgivelsen af angie 1.3.1 (en fork af nginx), der blev offentliggjort for en uge siden.\n<li class=\"l\"> Forbedret h\u00e5ndtering af buffere, der bruges ved automatisk at identificere HTTP\/2-forbindelser.\n<li class=\"l\"> Ydelsen ved opstart af konfigurationer med et stort antal &#171;location&#187;-direktiver er blevet forbedret.\n<li class=\"l\"> Problemer med nedbrud af arbejdsprocessen er blevet l\u00f8st, som observeret ved fors\u00f8g p\u00e5 at bruge HTTP\/2 uden. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/ssl-sertifikat\/\"   title=\"SSL\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2317\">SSL<\/a>.\n<li class=\"l\"> L\u00f8st ukorrekt behandling af den tilbagevendende header \u00abStatus\u00bb fra backend med en tom forklarende tekst.\n<li class=\"l\"> Der er rettet en hukommelsesl\u00e6kage under rekonfiguration, som opst\u00e5r ved kompilering med PCRE2-biblioteket.\n<li class=\"l\"> Der er foretaget en betydelig m\u00e6ngde reparationer og forbedringer relateret til underst\u00f8ttelsen af HTTP\/3-protokollen.    <\/ul>\n<p>Samtidigt blev njs 0.8.2, en JavaScript-interpretator, ogs\u00e5 frigivet. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/\"   title=\"webserver\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1188\">webserver<\/a> nginx. Njs-interpretatoren implementerer ECMAScript-standarder og giver mulighed for at udvide nginx's evner til at behandle anmodninger ved hj\u00e6lp af scripts i konfigurationen. Scripts kan anvendes i konfigurationsfilen til at definere avanceret logik til behandling af anmodninger, oprette konfigurationer, dynamisk generere svar, \u00e6ndre anmodninger\/svar eller hurtigt oprette stubbe til fejlretning i webapplikationer. I den nye version er der tilf\u00f8jet et console-objekt, der tilbyder metoderne error(), info(), log(), time(), timeEnd() og warn(). I fs-modulet er der tilf\u00f8jet metoden fs.existsSync().    <\/p>\n<p>Der kan ogs\u00e5 n\u00e6vnes udgivelsen af applikationsserveren NGINX Unit 1.31.1, som tilbyder en l\u00f8sning til at k\u00f8re webapplikationer p\u00e5 forskellige programmeringssprog (Python, PHP, Perl, Ruby, Go, JavaScript\/Node.js og Java). Under ledelse af NGINX Unit kan flere applikationer p\u00e5 forskellige programmeringssprog k\u00f8re samtidig, hvor opstartparametrene kan \u00e6ndres dynamisk uden behov for at redigere konfigurationsfiler og genstarte. Udover fejlrettelser i den nye version er det i Wasm-modulet tilladt at indl\u00e6se data, der er st\u00f8rre end 4 GB, og ved svar er der mulighed for at indstille HTTP-statuskoder.<br \/>\n<br
