Kot glavno kriptografsko knji\u017enico smo se odlo\u010dili uporabiti GnuTLS (potrebna je vsaj razli\u010dica 3.4.7). Poleg zmanj\u0161anja morebitnih gro\u017eenj, povezanih z odkrivanjem ranljivosti v vgrajenih implementacijah kriptoalgoritmov, je prehod na GnuTLS prav tako omogo\u010dil znatno pove\u010danje zmogljivosti pri uporabi \u0161ifriranja v SMB3. Pri testiranju s klientom CIFS iz jedra Linux 5.3 smo zabele\u017eili pove\u010danje hitrosti pisanja za trikrat, branja pa za 2,5-krat.\n<li class=\"l\"> Dodana je nova ozadje za iskanje na SMB-delitvah z uporabo protokola <noindex><a rel=\"nofollow\" href=\"https:\/\/wiki.samba.org\/index.php\/Spotlight\">Spotlight<\/a><\/noindex>, ki temelji na iskalniku  <noindex><a rel=\"nofollow\" href=\"https:\/\/www.elastic.co\/elasticsearch\">Elasticsearch<\/a><\/noindex> (prej je bila na voljo ozadje na osnovi <noindex><a rel=\"nofollow\" href=\"https:\/\/wiki.gnome.org\/Projects\/Tracker\">GNOME Tracker<\/a><\/noindex>).
