+## [1.0.5] - 2026-10-31
+
+### Added
+- **One-click desktop update.** The update button actually downloads, verifies (SHA-256) and installs the new version now, instead of only changing its own label. Works for all three desktop packages: AppImage (atomic self-replace), `.deb` (`dpkg -i`, no new password prompt — the app is already running as root by the time you click it), and the Windows installer (silent install). On Linux, the app restarts itself automatically; on Windows, the installer runs silently but the app does not reopen on its own yet — start it again once the install finishes.
+
+### Changed
+- **The repository moved to the Ciberfauna organization** (`ciberfauna/sabia`, was `lucasrguerra/sabia`). **Important notice for existing installations:** versions up to 1.0.4 have the old location baked into their update check; they will not find this release automatically. Download 1.0.5 once manually from the new Releases page, and future update checks will work through the new location.

+## [1.0.5] - 2026-10-31
+
+### Adicionado
+- **Atualização do app desktop em um clique.** O botão de atualizar agora baixa, confere (SHA-256) e instala a versão nova de verdade, em vez de só mudar o próprio texto. Funciona nos três pacotes do desktop: AppImage (substituição atômica), `.deb` (`dpkg -i`, sem pedir senha de novo — o app já roda como root quando você clica), e o instalador do Windows (instalação silenciosa). No Linux o app reabre sozinho; no Windows o instalador roda silencioso mas o app ainda não reabre por conta própria — abra de novo depois que a instalação terminar.
+
+### Alterado
+- **O repositório se mudou pra organização Ciberfauna** (`ciberfauna/sabia`, era `lucasrguerra/sabia`). **Aviso importante pra instalações existentes:** versões até a 1.0.4 têm o endereço antigo fixo na checagem de atualização e não vão encontrar esta versão sozinhas. Baixe a 1.0.5 manualmente uma vez na nova página de Releases, e as próximas verificações voltam a funcionar pelo novo endereço.
