Nesta vers\u00e3o, foi implementado suporte nativo para conjuntos de ferramentas de IA\/ML l\u00edderes da ind\u00fastria, como NVIDIA CUDA e AMD ROCm, tornando o Ubuntu 26.04 LTS a plataforma ideal para o desenvolvimento de IA e tarefas de produ\u00e7\u00e3o.\u201d<\/p>\n<p>John Seager, vice-presidente de desenvolvimento do Ubuntu na Canonical.<\/p>\n<\/blockquote>\n<p><\/noindex> Resumo das principais mudan\u00e7as:<\/p>\n<ul>\n<li> Abandono da sess\u00e3o X11 do GNOME e migra\u00e7\u00e3o para Wayland, o projeto upstream descontinuou o suporte ao X.Org, e a op\u00e7\u00e3o \u201cUbuntu on X11\u201d na tela de login do GDM n\u00e3o est\u00e1 dispon\u00edvel. Aplicativos que dependem do X11 funcionam atrav\u00e9s da camada de compatibilidade XWayland, instalada por padr\u00e3o, e esta solu\u00e7\u00e3o n\u00e3o se aplica a outros ambientes de desktop.  <\/li>\n<li> A Canonical substituiu a implementa\u00e7\u00e3o de refer\u00eancia do sudo pelo sudo-rs \u2014 uma alternativa escrita em Rust, compat\u00edvel com os arquivos existentes \/etc\/sudoers. A vers\u00e3o cl\u00e1ssica foi renomeada para sudo.ws e permanece nos reposit\u00f3rios; a troca \u00e9 feita atrav\u00e9s do sistema de alternativas. O sudo-rs inclui, por padr\u00e3o, a exibi\u00e7\u00e3o de asteriscos ao digitar a senha (pwfeedback).  <\/li>\n<li> Os comandos ls, cp, mv, cat e outras utilit\u00e1rios b\u00e1sicos da linha de comando agora s\u00e3o fornecidos pelo pacote rust-coreutils \u2014 um projeto uutils\/coreutils. No momento do lan\u00e7amento, a compatibilidade com a implementa\u00e7\u00e3o padr\u00e3o do GNU \u00e9 parcial, portanto, os GNU coreutils permanecem instalados como uma op\u00e7\u00e3o de backup e podem ser alternados atrav\u00e9s do update-alternatives.  <\/li>\n<li> A distribui\u00e7\u00e3o vem com o Linux 7.0 \u2014 o n\u00facleo foi lan\u00e7ado em 12 de abril de 2026. A transi\u00e7\u00e3o atrav\u00e9s do n\u00famero \u201credondo\u201d \u00e9 justificada pela tradi\u00e7\u00e3o de Linus Torvalds: o novo n\u00facleo, ap\u00f3s 6.19, recebeu o n\u00famero superior 7.0, em vez de 6.20. Nesta vers\u00e3o, o suporte para Rust no n\u00facleo foi transferido de status experimental para est\u00e1vel; um mecanismo de recupera\u00e7\u00e3o de metadados foi adicionado ao XFS. O framework sched_ext baseado em eBPF, que apareceu no Ubuntu ainda na vers\u00e3o 25.04, permite implementar escalonadores no espa\u00e7o do usu\u00e1rio.  <\/li>\n<li> Nas novas instala\u00e7\u00f5es, o Dracut \u00e9 utilizado como gerador da imagem de inicializa\u00e7\u00e3o em vez do initramfs-tools. A transi\u00e7\u00e3o ocorreu j\u00e1 na vers\u00e3o 25.10 do Ubuntu. O Dracut usa o systemd no initramfs e suporta Bluetooth e NVMe over Fabrics (NVMe-oF). O pacote initramfs-tools continua a ser suportado, e a troca entre implementa\u00e7\u00f5es \u00e9 poss\u00edvel se necess\u00e1rio.  <\/li>\n<li> Criptografia de disco baseada em TPM\n<p>O instalador recebeu suporte para criptografia completa de disco baseada em TPM 2 com Secure Boot obrigat\u00f3rio. Este recurso utiliza o n\u00facleo na forma de pacote snap e n\u00e3o abrange todos os chips TPM; o instalador informa se o TPM n\u00e3o \u00e9 compat\u00edvel. A chave de recupera\u00e7\u00e3o pode ser reemitida no aplicativo \u201cCentro de Seguran\u00e7a\u201d, e o utilit\u00e1rio de atualiza\u00e7\u00e3o de firmware alerta sobre firmwares que afetar\u00e3o o estado do TPM. A criptografia LUKS com senha ainda funciona e n\u00e3o requer TPM. Al\u00e9m disso, a instala\u00e7\u00e3o ao lado de uma parti\u00e7\u00e3o Windows criptografada com BitLocker foi aprimorada: atrav\u00e9s da se\u00e7\u00e3o \u201cConfigura\u00e7\u00f5es Avan\u00e7adas\u201d no instalador do Ubuntu, \u00e9 poss\u00edvel instalar com criptografia sem afetar o Windows.  <\/p>\n<\/li>\n<li> O ambiente de trabalho GNOME foi atualizado da vers\u00e3o 46 para a 50. As mudan\u00e7as mais not\u00e1veis ocorreram nos \u00edcones das pastas: preenchimento intenso com a cor de destaque da \u00e1rea de trabalho (por padr\u00e3o, laranja) e grava\u00e7\u00e3o fina dos emblemas. A maior parte do conjunto Yaru foi reformulada, e os \u00edcones do LibreOffice, do aplicativo Snapshot e da lixeira foram atualizados.  <\/li>\n<\/ul>\n<p><noindex><\/p>\n<p>Para sua informa\u00e7\u00e3o: Ubuntu \u00e9 uma distribui\u00e7\u00e3o GNU\/Linux baseada no Debian.
