As compila\u00e7\u00f5es do MySQL Community Server 8.3.0 est\u00e3o dispon\u00edveis para todas as principais distribui\u00e7\u00f5es Linux, FreeBSD, macOS e Windows.    <\/p>\n<p>MySQL 8.3.0 \u00e9 a terceira vers\u00e3o, criada no \u00e2mbito de um novo modelo de lan\u00e7amento que inclui dois tipos de ramos MySQL \u2014 'Inova\u00e7\u00e3o' e 'LTS'. Os ramos de Inova\u00e7\u00e3o, que incluem MySQL 8.1, 8.2 e 8.3, s\u00e3o recomendados para quem deseja acesso antecipado a novas funcionalidades. Esses ramos s\u00e3o publicados a cada 3 meses e suportados apenas at\u00e9 a publica\u00e7\u00e3o do pr\u00f3ximo lan\u00e7amento significativo (por exemplo, ap\u00f3s o surgimento do ramo 8.3, o suporte para o ramo 8.2 \u00e9 encerrado). Os ramos LTS s\u00e3o recomendados para implementa\u00e7\u00f5es que precisam de previsibilidade e um comportamento duradouro. Os ramos LTS ser\u00e3o lan\u00e7ados a cada dois anos e suportados por 5 anos, al\u00e9m de um per\u00edodo adicional de 3 anos de suporte estendido. O lan\u00e7amento LTS do MySQL 8.4 est\u00e1 previsto para a primavera de 2024, ap\u00f3s o qual um novo ramo de Inova\u00e7\u00e3o 9.0 ser\u00e1 estabelecido.        <\/p>\n<p>Principais mudan\u00e7as no MySQL 8.3:  <\/p>\n<ul>\n<li class=\"l\"> Foram corrigidas 25 vulnerabilidades, das quais uma (CVE-2023-5363, afetando o OpenSSL) pode ser explorada remotamente. O problema mais grave, relacionado ao protocolo Kerberos, recebeu um n\u00edvel de severidade de 8.8. Vulnerabilidades menos graves com n\u00edvel de severidade 6.5 afetam o otimizador, UDF, DDL, DML, replica\u00e7\u00e3o, sistema de privil\u00e9gios e mecanismos de criptografia.\n<li class=\"l\"> Na plataforma Linux, a support for the mold linker foi adicionada. Para habilit\u00e1-la, \u00e9 necess\u00e1ria a op\u00e7\u00e3o '-DWITH_LD=mold|lld'.\n<li class=\"l\"> Os requisitos para o padr\u00e3o C++ suportado pelo compilador foram elevados de C++17 para C++20.\n<li class=\"l\"> O suporte para a constru\u00e7\u00e3o com bibliotecas externas Boost C++ foi encerrado \u2014 ao compilar o MySQL, agora s\u00e3o usadas apenas bibliotecas Boost internas. As op\u00e7\u00f5es de constru\u00e7\u00e3o WITH_BOOST, DOWNLOAD_BOOST e DOWNLOAD_BOOST_TIMEOUT foram removidas do CMake.\n<li class=\"l\"> O suporte para compila\u00e7\u00e3o no Visual Studio 2022 foi encerrado. A vers\u00e3o m\u00ednima suportada do compilador Clang foi aumentada de Clang 10 para Clang 12.\n<li class=\"l\"> No MySQL Enterprise Edition, foi adicionada a compatibilidade com a coleta de telemetria com m\u00e9tricas de desempenho <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/server\/dts-los-angeles\/\"   title=\"servidor\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3680\">servidor<\/a> no formato OpenTelemetry e a transmiss\u00e3o de dados para um manipulador de rede que suporte esse formato.\n<li class=\"l\"> O formato de identificadores GTID (identificador de transa\u00e7\u00e3o global) usado na replica\u00e7\u00e3o para identificar grupos de transa\u00e7\u00f5es foi expandido. O novo formato GTID \u00e9 'UUID::NUMBER' (em vez de 'UUID:NUMBER'), onde TAG \u00e9 uma string arbitr\u00e1ria que permite nomear de forma \u00fanica um determinado grupo de transa\u00e7\u00f5es para facilitar o processamento e an\u00e1lise.\n<li class=\"l\"> Duas novas vari\u00e1veis 'Deprecated_use_i_s_processlist_count' e 'Deprecated_use_i_s_processlist_last_timestamp' foram adicionadas para rastrear o uso da tabela obsoleta INFORMATION_SCHEMA.PROCESSLIST.\n<li class=\"l\"> Definir a vari\u00e1vel de ambiente AUTHENTICATION_PAM_LOG n\u00e3o resulta mais na exibi\u00e7\u00e3o de senhas em mensagens de diagn\u00f3stico (para mencionar a senha, \u00e9 necess\u00e1rio atribuir o valor PAM_LOG_WITH_SECRET_INFO).\n<li class=\"l\"> Adicionada a tabela tp_connections com informa\u00e7\u00f5es sobre cada conex\u00e3o no pool de threads.\n<li class=\"l\"> Uma vari\u00e1vel de sistema 'explain_json_format_version' foi adicionada para selecionar a vers\u00e3o do formato JSON utilizada nas express\u00f5es 'EXPLAIN FORMAT=JSON'.\n<li class=\"l\"> No armazenamento InnoDB, os par\u00e2metros '--innodb' e '--skip-innodb', que foram declarados obsoletos na vers\u00e3o MySQL 5.6, foram removidos. O plugin memcached para InnoDB, declarado obsoleto no MySQL 8.0.22, tamb\u00e9m foi removido.\n<li class=\"l\"> Removidas algumas configura\u00e7\u00f5es e op\u00e7\u00f5es da linha de comando relacionadas \u00e0 replica\u00e7\u00e3o que foram declaradas obsoletas nas vers\u00f5es anteriores: \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.
