Kao glavna kripto biblioteka odlu\u010deno je koristiti GnuTLS (minimalna verzija 3.4.7). Osim smanjenja mogu\u0107ih prijetnji povezanih s otkrivanjem ranjivosti u ugra\u0111enim implementacijama kriptoalgoritama, prijelaz na GnuTLS tako\u0111er je omogu\u0107io zna\u010dajno pove\u0107anje performansi pri kori\u0161tenju enkripcije u SMB3. Tijekom testiranja s implementacijom CIFS klijenta iz Linux kernela 5.3 zabilje\u017eeno je pove\u0107anje brzine pisanja od 3 puta, a \u010ditanja od 2.5 puta.\n<li class=\"l\"> Dodana je nova pozadina za pretra\u017eivanje na SMB dijelovima koriste\u0107i protokol <noindex><a rel=\"nofollow\" href=\"https:\/\/wiki.samba.org\/index.php\/Spotlight\">Spotlight<\/a><\/noindex>, temeljen na pretra\u017eiva\u010dkom motoru  <noindex><a rel=\"nofollow\" href=\"https:\/\/www.elastic.co\/elasticsearch\">Elasticsearch<\/a><\/noindex> (ranije je bila dostupna pozadina zasnovana na <noindex><a rel=\"nofollow\" href=\"https:\/\/wiki.gnome.org\/Projects\/Tracker\">GNOME Tracker<\/a><\/noindex>).

Zadana vrijednost postavke &#171;spotlight backend&#187; promijenjena je na &#171;noindex&#187; (za Tracker ili Elasticsearch potrebno je izri\u010dito postaviti vrijednosti &#171;tracker&#187; ili &#171;elasticsearch&#187;).\n<li class=\"l\"> Promijenjeno je pona\u0161anje operacija &#8216;net ads kerberos pac save&#8217; i &#8216;net eventlog export&#8217;, koje sada ne prepisuju datoteku, a u slu\u010daju poku\u0161aja izvoza u postoje\u0107u datoteku prikazuju gre\u0161ku.\n<li class=\"l\"> U samba-tool-u je pobolj\u0161ano dodavanje kontaktnih zapisa za \u010dlanove grupa. Dok se ranije, pomo\u0107u naredbe &#8216;samba-tool group addmembers&#8217;, moglo jednostavno dodati korisnike, grupe i ra\u010dunala kao nove \u010dlanove grupa, sada je omogu\u0107ena podr\u0161ka za dodavanje kontakata kao \u010dlanova grupa.\n<li class=\"l\"> U samba-tool-u je omogu\u0107ena filtracija prema organizacijskim jedinicama (OU, Organizational Unit) ili podstablu.

Kada se koristi polling, io_uring zna\u010dajno nadma\u0161uje aio u performansama. Trenutno, na temelju io_uring, u Sambi je implementirana podr\u0161ka za SMB_VFS_{PREAD,PWRITE,FSYNC}_SEND\/RECV i smanjeni su tro\u0161kovi podr\u0161ke za odr\u017eavanje skupa vi\u0161ekratnog izvr\u0161avanja (threadpool) u korisni\u010dkom prostoru pri primjeni predlo\u017eenog standardnog VFS b backend-a.

U Heimdal-DC uklonjen je kod weak-crypto.\n<li class=\"l\"> Uklonjen je modul vfs_netatalk, koji je ostao bez podr\u0161ke i izgubio relevantnost.\n<li class=\"l\"> Proklamiran je zastarjeli backend BIND9_FLATFILE, koji \u0107e biti uklonjen u jednom od sljede\u0107ih izdanja.\n<li class=\"l\"> Knji\u017enica zlib uklju\u010dena je me\u0111u ovisnosti za izgradnju. Ugra\u0111ena implementacija zlib uklonjena je iz kodne baze (kod se temeljio na staroj verziji zlib koja nije ispravno radila podr\u0161ku za enkripciju).\n<li class=\"l\"> Uspostavljen je fuzzing-testiranje kodne baze, uklju\u010duju\u0107i uslugu<br \/>\noss-fuzz.
