Uma nova API foi adicionada nesta vers\u00e3o<br \/>\n QImage::convertTo para convers\u00e3o de formatos de imagem. Novos m\u00e9todos clear, reserve e capacity foram adicionados \u00e0 classe QPainterPath;<\/p>\n<li class=\"l\"> No m\u00f3dulo Qt QML, que fornece ferramentas para o desenvolvimento de interfaces usando a linguagem QML, melhorou-se o suporte a tipos enumerados definidos em c\u00f3digo C++. A manipula\u00e7\u00e3o de valores 'null' na fase de compila\u00e7\u00e3o foi otimizada. Foi adicionada a capacidade de gerar tabelas de fun\u00e7\u00f5es em sistemas Windows de 64 bits, permitindo a execu\u00e7\u00e3o de unwind para fun\u00e7\u00f5es JIT-compiladas;\n<li class=\"l\"> No Qt Quick, o objeto TableView agora permite ocultar colunas e linhas da tabela;\n<li class=\"l\"> No Qt Quick Controls 2 foi adicionado o tipo <noindex><a rel=\"nofollow\" href=\"https:\/\/doc-snapshots.qt.io\/qt5-dev\/qml-qtquick-controls2-splitview.html\">SplitView<\/a><\/noindex> para o posicionamento horizontal ou vertical de elementos com um divisor m\u00f3vel entre cada elemento. Para \u00edcones, foi adicionada uma propriedade que permite gerenciar seu cache;\n<li class=\"l\"> O motor da Web Qt WebEngine foi atualizado para o estado Chromium 73 e aprimorado com suporte a um visualizador de PDF integrado, apresentado como um complemento interno. Nesta nova vers\u00e3o, tamb\u00e9m foi adicionado um armazenamento de certificados de cliente locais e suporte a certificados a partir de QML. Uma API de Notifica\u00e7\u00f5es da Web foi adicionada. O suporte para identifica\u00e7\u00e3o de interceptadores de solicita\u00e7\u00f5es URL foi implementado;\n<li class=\"l\"> No m\u00f3dulo Qt Network para sockets SSL, o suporte a canais seguros (Secure Channel) foi adicionado, juntamente com a capacidade de verificar o status de certificados usando o protocolo OCSP (Online Certificate Status Protocol).

Para Windows e macOS, foi adicionada a possibilidade de usar o framework GStreamer. Para Android, foi acrescentado suporte para pap\u00e9is de som;\n<li class=\"l\"> O m\u00f3dulo Qt KNX foi atualizado com suporte ao padr\u00e3o hom\u00f4nimo para automa\u00e7\u00e3o residencial. Uma API foi adicionada para estabelecer conex\u00f5es seguras de cliente com o servidor KNXnet, que podem ser utilizadas para enviar mensagens de forma segura para o barramento KNX e controlar dispositivos compat\u00edveis com KNX;\n<li class=\"l\"> O indicativo de desenvolvimento experimental foi removido da API C++ do m\u00f3dulo Qt OPC UA, que oferece suporte ao padr\u00e3o de comunica\u00e7\u00e3o industrial OPC\/UA. Uma API experimental para QML foi adicionada;\n<li class=\"l\"> Foi adicionado um novo m\u00f3dulo experimental Qt CoAP (Constrained Application Protocol) com a implementa\u00e7\u00e3o da parte cliente do protocolo M2M, utilizado para criar redes de dispositivos de Internet das Coisas. O suporte para DTLS (Datagram TLS) sobre UDP foi implementado;\n<li class=\"l\"> Corre\u00e7\u00f5es e melhorias foram feitas no conjunto de m\u00f3dulos 'Qt for Python' para criar aplicativos gr\u00e1ficos na linguagem Python usando Qt5 (os desenvolvedores Python t\u00eam acesso \u00e0 maior parte da API C++ do Qt). O Qt for Python \u00e9 baseado no m\u00f3dulo PySide2 e continua seu desenvolvimento (na verdade, sob um novo nome, a primeira vers\u00e3o do PySide com suporte ao Qt 5 \u00e9 oferecida);\n<li class=\"l\"> Um novo m\u00f3dulo experimental foi adicionado <noindex><a rel=\"nofollow\" href=\"https:\/\/doc-snapshots.qt.io\/qt5-5.13\/qtlottieanimation-index.html\">Qt Lottie<\/a><\/noindex>, fornecendo uma API ampliada para QML, permitindo renderizar gr\u00e1ficos e anima\u00e7\u00f5es exportadas no formato JSON atrav\u00e9s do plugin Bodymovin do pacote Adobe After Effects. Com o QtLottie, o designer pode preparar efeitos de anima\u00e7\u00e3o em seu aplicativo preferido, enquanto o desenvolvedor pode conectar diretamente os arquivos exportados \u00e0 interface dos aplicativos em QtQuick. O QtLottie inclui um micro-motor embutido para executar anima\u00e7\u00f5es, recortes, manipula\u00e7\u00e3o de camadas e outros efeitos. O motor est\u00e1 acess\u00edvel atrav\u00e9s do elemento QML LottieAnimation, que pode ser controlado a partir do c\u00f3digo QML da mesma forma que quaisquer outros elementos do QtQuick;\n<li class=\"l\"> No Qt Wayland Compositor, um sistema de renderiza\u00e7\u00e3o multithread para dispositivos embarcados baseado no protocolo Wayland, foi garantido o suporte para os protocolos linux-dmabuf-unstable-v1 e wp_viewporter. O suporte ao protocolo fullscreen-shell-unstable-v1 foi adicionado nos componentes da plataforma para Wayland;\n<li class=\"l\"> O m\u00f3dulo de suporte \u00e0 plataforma Android agora permite o uso de di\u00e1logos nativos para trabalhar com arquivos. Os requisitos para a vers\u00e3o m\u00ednima da plataforma foram elevados para Android 5.0 (n\u00edvel de API 21);\n<li class=\"l\"> No Qt 3D, foi adicionada a fun\u00e7\u00e3o de importa\u00e7\u00e3o e exporta\u00e7\u00e3o de manipuladores de textura OpenGL. O suporte inicial para importa\u00e7\u00e3o de cenas glTF 2.0 foi implementado;\n<li class=\"l\"> Os m\u00f3dulos Qt Script, Qt Quick Controls 1 e Qt XmlPatterns foram declarados obsoletos e ser\u00e3o removidos em uma das pr\u00f3ximas vers\u00f5es. O m\u00f3dulo Qt Canvas 3D foi removido.<br \/>\n    Ap\u00f3s seis meses de desenvolvimento, o lan\u00e7amento do framework multiplataforma foi conclu\u00eddo<\/p>\n<\/ul>\n<p><noindex><a
