Bygningerne af MySQL Community Server 8.3.0 er forberedt til alle st\u00f8rre distributioner af Linux, FreeBSD, macOS og Windows.    <\/p>\n<p>MySQL 8.3.0 er den tredje udgivelse, der er dannet inden for den nye model for udgivelsesdannelse, som omfatter to typer MySQL-grene \u2014 \u00abInnovation\u00bb og \u00abLTS\u00bb. Innovation-grenene, som omfatter MySQL 8.1, 8.2 og 8.3, anbefales til dem, der \u00f8nsker tidligt at f\u00e5 adgang til ny funktionalitet. Disse grene offentligg\u00f8res hvert 3. m\u00e5ned og underst\u00f8ttes kun indtil offentligg\u00f8relsen af den n\u00e6ste betydelige udgivelse (for eksempel stopper underst\u00f8ttelsen af gren 8.2 efter frigivelsen af gren 8.3). LTS-grenene anbefales til implementeringer, der har brug for forudsigelighed og langvarig bevaring af u\u00e6ndret adf\u00e6rd. LTS-grene vil blive udgivet hvert andet \u00e5r og underst\u00f8ttes i 5 \u00e5r, som derudover kan f\u00e5 yderligere 3 \u00e5r med udvidet support. Det forventes, at LTS-udgivelsen MySQL 8.4 kommer i for\u00e5ret 2024, hvorefter en ny Innovation-gren 9.0 vil blive dannet.        <\/p>\n<p>Hoved\u00e6ndringer i MySQL 8.3:  <\/p>\n<ul>\n<li class=\"l\"> 25 s\u00e5rbarheder er blevet rettet, hvoraf en (CVE-2023-5363, der p\u00e5virker OpenSSL) kan udnyttes eksternt. Den mest alvorlige problemstilling knyttet til brugen af Kerberos-protokollen er blevet tildelt en alvorlighedsgrad p\u00e5 8,8. Mindre alvorlige s\u00e5rbarheder med en alvorlighedsgrad p\u00e5 6,5 p\u00e5virker optimeringssystemet, UDF, DDL, DML, replikation, priviligeringssystemet og krypteringsv\u00e6rkt\u00f8jer.\n<li class=\"l\"> Der er tilf\u00f8jet st\u00f8tte til linker mold p\u00e5 Linux-platformen.

Den mindst underst\u00f8ttede version af Clang-v\u00e6rkt\u00f8jet er h\u00e6vet fra Clang 10 til Clang 12.\n<li class=\"l\"> I MySQL Enterprise Edition er der tilf\u00f8jet support til at indsamle telemetri med pr\u00e6stationsmetrikker <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3680\">server<\/a> i OpenTelemetry-formatet og sende data til en netv\u00e6rkshandler, der underst\u00f8tter dette format.\n<li class=\"l\"> Formatet for GTID (global transaction identifier), der anvendes til replikation til identifikation af grupper af transaktioner, er blevet udvidet. Det nye GTID-format er \u00abUUID::NUMBER\u00bb (i stedet for \u00abUUID:NUMBER\u00bb), hvor TAG er en vilk\u00e5rlig streng, der g\u00f8r det muligt at tildele unikke navne til en bestemt gruppe transaktioner for at lette behandlingen og analysen.\n<li class=\"l\"> To nye variable \u00abDeprecated_use_i_s_processlist_count\u00bb og \u00abDeprecated_use_i_s_processlist_last_timestamp\u00bb er blevet tilf\u00f8jet for at spore brugen af den for\u00e6ldede tabel INFORMATION_SCHEMA.PROCESSLIST.\n<li class=\"l\"> Indstillingen af milj\u00f8variablen AUTHENTICATION_PAM_LOG f\u00f8rer ikke l\u00e6ngere til, at adgangskoder vises i diagnostiske meddelelser (for at n\u00e6vne adgangskoden kr\u00e6ver det, at v\u00e6rdien PAM_LOG_WITH_SECRET_INFO tildeles).\n<li class=\"l\"> Der er tilf\u00f8jet en tabel tp_connections med oplysninger om hver forbindelse i tr\u00e5d-poolen.\n<li class=\"l\"> En systemvariabel \u00abexplain_json_format_version\u00bb er blevet tilf\u00f8jet for at v\u00e6lge versionen af JSON-formatet, der anvendes i \u00abEXPLAIN FORMAT=JSON\u00bb udtryk.\n<li class=\"l\"> Indstillingerne \u00ab\u2014innodb\u00bb og \u00ab\u2014skip-innodb\u00bb er blevet fjernet fra InnoDB-lageret, som er blevet erkl\u00e6ret for\u00e6ldet siden udgivelsen af MySQL 5.6. Memcached-pluginet til InnoDB, som blev erkl\u00e6ret for\u00e6ldet i MySQL 8.0.22, er blevet fjernet.\n<li class=\"l\"> Nogle indstillinger og kommandolinjeindstillinger relateret til replikering, der er erkl\u00e6ret for\u00e6ldede i tidligere versioner, er fjernet: \u2018--slave-rows-search-algorithms\u2019, \u2018--relay-log-info-file\u2019, \u2018--relay-log-info-repository\u2019, \u2018--master-info-file\u2019, \u2018--master-info-repository\u2019, \u2018log_bin_use_v1_events\u2019, \u2018transaction_write_set_extraction\u2019, \u2018group_replication_ip_whitelist\u2019, \u2018group_replication_primary_member\u2019.
