As imagens de instala\u00e7\u00e3o foram preparadas para as arquiteturas amd64, i386, powerpc, powerpc64, powerpc64le, powerpcspe, armv7, aarch64 e riscv64. Al\u00e9m disso, foram preparadas compila\u00e7\u00f5es para sistemas de virtualiza\u00e7\u00e3o (QCOW2, VHD, VMDK, raw) e ambientes de nuvem Amazon EC2, Google Compute Engine e Vagrant.       <\/p>\n<p>A pr\u00f3xima atualiza\u00e7\u00e3o do FreeBSD 14.4 est\u00e1 agendada para mar\u00e7o de 2026. O suporte \u00e0 vers\u00e3o atual do FreeBSD 14.3 ser\u00e1 mantido at\u00e9 30 de junho de 2026, e a vers\u00e3o anterior, FreeBSD 14.2, at\u00e9 30 de setembro de 2025. De modo geral, a linha do FreeBSD 14 ser\u00e1 suportada at\u00e9 30 de novembro de 2028, enquanto a linha do FreeBSD 13.x at\u00e9 30 de abril de 2026. O primeiro lan\u00e7amento da pr\u00f3xima linha significativa, FreeBSD 15, que encerrar\u00e1 o suporte para arquiteturas de 32 bits (com exce\u00e7\u00e3o de armv7 e do modo COMPAT_FREEBSD32), est\u00e1 previsto para dezembro de 2025.        <\/p>\n<p>As principais altera\u00e7\u00f5es no FreeBSD 14.3:  <\/p>\n<ul>\n<li class=\"l\"> Na camada LinuxKPI, aplicada para executar drivers Linux no FreeBSD, foi implementado suporte aos padr\u00f5es Wi-Fi 4 (802.11n) e Wi-Fi 5 (802.11ac), bem como a delega\u00e7\u00e3o de opera\u00e7\u00f5es de criptografia aos adaptadores de rede. Essas funcionalidades est\u00e3o envolvidas no driver iwlwifi, baseado no c\u00f3digo do driver hom\u00f4nimo do kernel Linux e que suporta chips sem fio da Intel usados em laptops modernos. Os firmwares iwlwififw para o driver Intel iwlwifi foram removidos do sistema base em favor da instala\u00e7\u00e3o a partir de ports e do uso da utilidade fwget.\n<p>O driver rtw88 para chips sem fio Realtek, com suporte 802.11n\/ac (RTL8723DE, RTL8821CE, RTL8822*), foi estabilizado e isento de vazamentos de mem\u00f3ria, utilizando tamb\u00e9m c\u00f3digo do Linux por meio do LinuxKPI.      <\/p>\n<li class=\"l\"> Nos reposit\u00f3rios Docker e GitHub, come\u00e7ou a publica\u00e7\u00e3o de imagens de cont\u00eaineres no formato OCI.\n<li class=\"l\"> As vers\u00f5es dos componentes de terceiros foram atualizadas: LLVM 19.1.7 (antes 18.1.6), OpenSSH 9.9p2, OpenZFS 2.2.7, xz 5.8.1, expat 2.7.1, less 668, file 5.46, OpenSSL 3.0.16.\n<li class=\"l\"> Para sistemas ARM64, foi adicionada a suporte ao hotplug de placas PCIe.\n<li class=\"l\"> Na API MAC (Mandatory Access Control), foi implementado suporte a par\u00e2metros para vincula\u00e7\u00e3o de pol\u00edticas a ambientes jail.\n<li class=\"l\"> Foi adicionado o sistema de chamada setcred para a troca at\u00f4mica de credenciais do processo, como euid, ruid, grupos e labels de controle de acesso. Para executar comandos sob outro usu\u00e1rio, foi preparada a utilidade mdo, semelhante \u00e0 utilidade su, mas utilizando em vez de setuid o m\u00f3dulo do kernel mac_do e a chamada de sistema setcred.\n<li class=\"l\"> No m\u00f3dulo mac_do, que permite definir pol\u00edticas que autorizam usu\u00e1rios n\u00e3o privilegiados a modificar credenciais de processos, \u00e9 permitido aplicar uma regra a v\u00e1rios usu\u00e1rios e grupos.\n<li class=\"l\"> Foi adicionada a suporte para vincular a execu\u00e7\u00e3o do sysctl ao ambiente jail especificado, permitindo ao ambiente pai visualizar e alterar o estado do n\u00facleo no jail filho. A utilidade sysctl agora possui flags para filtrar vari\u00e1veis relacionadas a jail e vnet. Por exemplo, para definir o par\u00e2metro net.fibs em um jail chamado \u2018foo\u2019, agora pode-se executar \u2018sysctl -j foo net.fibs=2\u2019.\n<li class=\"l\"> A utilidade ip6addrctl recebeu a op\u00e7\u00e3o \u2018-j\u2019 para aplicar configura\u00e7\u00f5es vinculadas ao ambiente jail especificado, facilitando o gerenciamento de endere\u00e7os na pilha de rede virtual no jail.\n<li class=\"l\"> O filtro de pacotes pf adicionou o par\u00e2metro \u2018net.pf.default_to_drop\u2019 para habilitar o modo de descartar pacotes por padr\u00e3o. O valor pode ser definido em rela\u00e7\u00e3o a pilhas de rede virtuais (vnet) no jail.\n<li class=\"l\"> Agora \u00e9 permitido modificar os par\u00e2metros do sysctl na pilha de rede virtual (vnet) a partir do bootloader inicial.\n<li class=\"l\"> No subsistema de \u00e1udio, foi implementada a aloca\u00e7\u00e3o din\u00e2mica (conforme necess\u00e1rio) de canais virtuais (vchan) para grava\u00e7\u00e3o e reprodu\u00e7\u00e3o de \u00e1udio.\n<li class=\"l\"> O driver mpi3mr para controladores PCIe Broadcom MPIMR 3.0 IT\/IR SAS foi atualizado e ativado no n\u00facleo base (GENERIC).\n<li class=\"l\"> Os drivers rtw88 e rtw89 para adaptadores sem fio com chips Realtek est\u00e3o sincronizados com o n\u00facleo Linux 6.14.\n<li class=\"l\"> O firmware iwmbtfw e o port iwmbt-firmware agora d\u00e3o suporte a adaptadores Bluetooth Intel 9260\/9560.\n<li class=\"l\"> Apoio ampliado para controladores Ethernet nos drivers ix (Intel), igc (Intel) e bnxt (Broadcom).\n<li class=\"l\"> Apoio melhorado para conex\u00e3o a quente de dispositivos em ambientes de nuvem AWS EC2 baseados em arquiteturas x86 e arm64 (\u2018Graviton\u2019).\n<li class=\"l\"> Na utilidade ps, a l\u00f3gica de tratamento da flag \u2018-U\u2019 foi alterada, agora filtrando processos pelo RUID (Identifica\u00e7\u00e3o do Usu\u00e1rio Real), em vez do EUID (Identifica\u00e7\u00e3o do Usu\u00e1rio Eficaz), conforme definido na especifica\u00e7\u00e3o POSIX.\n<li class=\"l\"> Na ferramenta grep, o seguimento de links simb\u00f3licos foi desativado por padr\u00e3o durante a pesquisa recursiva.\n<li class=\"l\"> No gerenciador de pacotes pkg (\/etc\/pkg\/FreeBSD.conf), foi adicionado um novo reposit\u00f3rio FreeBSD-kmods, que cont\u00e9m m\u00f3dulos de n\u00facleo compilados para a vers\u00e3o 14.3-RELEASE.\n<li class=\"l\"> A base de chaves p\u00fablicas \/etc\/publickey, baseada no algoritmo DES, foi declarada obsoleta.\n<li class=\"l\"> Um aviso sobre a remo\u00e7\u00e3o do gerenciador de volumes l\u00f3gicos gvinum foi adicionado na ramifica\u00e7\u00e3o FreeBSD 15. O desenvolvimento do Gvinum parou h\u00e1 cerca de 15 anos, e no c\u00f3digo existem uma s\u00e9rie de problemas conhecidos que ningu\u00e9m se disp\u00f4s a corrigir. Em vez de gvinum, \u00e9 recomendado usar gconcat, gmirror, gstripe, graid ou zfs.\n<li class=\"l\"> Foi adicionado um aviso sobre a iminente remo\u00e7\u00e3o do driver de console syscons, que \u00e9 incompat\u00edvel com UEFI, n\u00e3o suporta UTF-8 e ainda utiliza um bloqueio global do kernel. N\u00e3o foi determinado qual vers\u00e3o interromper\u00e1 o suporte ao syscons, mas a remo\u00e7\u00e3o do bloqueio global do kernel \u00e9 esperada na FreeBSD 16.            <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=63382\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u043e\u0441\u043b\u0435 \u0448\u0435\u0441\u0442\u0438 \u043c\u0435\u0441\u044f\u0446\u0435\u0432 \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u043a\u0438 \u0441\u0444\u043e\u0440\u043c\u0438\u0440\u043e\u0432\u0430\u043d \u0440\u0435\u043b\u0438\u0437 FreeBSD 14.3. \u0423\u0441\u0442\u0430\u043d\u043e\u0432\u043e\u0447\u043d\u044b\u0435 \u043e\u0431\u0440\u0430\u0437\u044b \u043f\u043e\u0434\u0433\u043e\u0442\u043e\u0432\u043b\u0435\u043d\u044b \u0434\u043b\u044f \u0430\u0440\u0445\u0438\u0442\u0435\u043a\u0442\u0443\u0440 amd64, i386, powerpc, powerpc64, powerpc64le, powerpcspe, armv7, aarch64 \u0438 riscv64. \u0414\u043e\u043f\u043e\u043b\u043d\u0438\u0442\u0435\u043b\u044c\u043d\u043e \u043f\u043e\u0434\u0433\u043e\u0442\u043e\u0432\u043b\u0435\u043d\u044b \u0441\u0431\u043e\u0440\u043a\u0438 \u0434\u043b\u044f \u0441\u0438\u0441\u0442\u0435\u043c \u0432\u0438\u0440\u0442\u0443\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0438 (QCOW2, VHD, VMDK, raw) \u0438 \u043e\u0431\u043b\u0430\u0447\u043d\u044b\u0445 \u043e\u043a\u0440\u0443\u0436\u0435\u043d\u0438\u0439 Amazon EC2, Google Compute Engine \u0438 Vagrant. \u0421\u043b\u0435\u0434\u0443\u044e\u0449\u0435\u0435 \u043e\u0431\u043d\u043e\u0432\u043b\u0435\u043d\u0438\u0435 FreeBSD 14.4 \u0437\u0430\u043f\u043b\u0430\u043d\u0438\u0440\u043e\u0432\u0430\u043d\u043e \u043d\u0430 \u043c\u0430\u0440\u0442 2026 \u0433\u043e\u0434\u0430. \u041f\u043e\u0434\u0434\u0435\u0440\u0436\u043a\u0430 \u043d\u044b\u043d\u0435\u0448\u043d\u0435\u0433\u043e \u0432\u044b\u043f\u0443\u0441\u043a\u0430 [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-136074","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.3 -
