- Caminhos e conteúdo: GOW3_ -> ISSN_, Gow3 -> Issn, gow3 -> issn, tags "gow3:" -> "port:". Créditos e links ao gow3_pc (Felipe Prado) mantidos; a documentação herdada do port do God of War III foi para docs/base/. - run.py aceita as variáveis GOW3_ antigas (viram ISSN_ quando a nova não está definida). - build.sh: se o patch antigo do fsr-vulkan já estiver aplicado no submódulo, volta ao commit fixado e aplica o novo. - Menu do jogo: os cheats do God of War III só aparecem quando algum é suportado. - Launcher 0.2.0: tema novo, seção inFAMOUS (Efeitos, prioridade do compute, distância de detalhe), "Salvar relatório de bug", sem os cheats do GoW3, atualização pelos releases deste repositório (silenciosa enquanto ele for privado), traduções em português. - README-Windows: 0.2.0 e novidades.
