 ## [Unreleased]

+## [2.1.2] - 2026-03-30
+
+### Adicionado
+
+- Preferências: nova configuração de tamanho máximo por arquivo de anexo (5, 10, 25, 50 ou 100 MB), persistida no banco e respeitada em todos os pontos de upload
+- Lançamentos: novo escopo `"period"` na ação em lote, que aplica a alteração a todos os lançamentos do período sem sobrescrever o pagador individual de cada um
+### Corrigido
+
+- Lançamentos: ao editar um lançamento de série, uploads e remoções de anexo agora aguardam a escolha de escopo da ação em lote antes de serem executados, evitando que o anexo fosse aplicado no lançamento errado
+- Lançamentos: ação em lote com escopo `"period"` não sobrescreve mais o `payerId` individual de cada lançamento ao alterar o pagador
+
+### Alterado
+
+- Configurações: redesign visual da página com separadores entre seções e títulos maiores
+- Configurações: seção "Extrato e lançamentos" renomeada para "Lançamentos"
+
+## [2.1.1] - 2026-03-29
+
+### Adicionado
+
+- Navbar: novo componente `NavbarShell` que unifica a estrutura da barra de navegação entre o app e a landing page
+- UI: nova variante `navbar` no componente `Button`, centralizando os estilos de botões usados dentro da navbar
+- Analytics: integração com Umami self-hosted via script tag no layout raiz
+
+### Alterado
+
+- Navbar: `AnimatedThemeToggler` e `RefreshPageButton` passam a aceitar prop `variant` para adaptar estilos ao contexto (navbar ou sidebar)
+- Navbar: estilos inline duplicados de `nav-styles.ts` migrados para a variante `navbar` do Button
+- Logo: prop `showVersion` removida; prop `colorIcon` passa a aplicar filtro de cor também no variant `compact`
+- Scripts: `mockup` renomeado para `db:seed`; `db:enableExtensions` renomeado para `db:extensions`; script `dev-env` removido
+- Landing: `MobileNav` simplificado com a remoção da prop `triggerClassName`
+
+### Removido
+
+- Navbar: arquivo `nav-styles.ts` removido após migração dos estilos para a variante `navbar`
+- Dependências: `@vercel/analytics` e `@vercel/speed-insights` removidos (substituídos pelo Umami self-hosted)
+
+## [2.1.0] - 2026-03-28
+
+### Adicionado
+
+- Lançamentos: suporte a anexos em transações com upload direto para storage compatível com S3, persistência em tabelas dedicadas (`anexos` e `lancamento_anexos`) e ações de visualizar/remover no detalhe do lançamento
+- Infraestrutura: novo workflow `.github/workflows/release.yml` para criar tag e GitHub Release automaticamente a partir da versão do `package.json` e da entrada correspondente no `CHANGELOG.md`
+
+### Alterado
+
+- Anexos: upload agora exige token assinado por arquivo, valida propriedade da transação também na leitura/remoção e confere tamanho/tipo do objeto no storage antes de persistir o vínculo no banco
+
+### Corrigido
+
+- Lançamentos: criação de transações no cartão de crédito agora bloqueia períodos cujas faturas já estão pagas, evitando divergência no relatório de análise de parcelas

+## ☁️ Storage S3 Compatível
+
+O suporte a anexos de lançamentos usa upload direto com URL pré-assinada. Essa configuração é opcional, mas passa a ser necessária se você quiser habilitar anexos no app.
+
+### Variáveis
+
+```env
+S3_ENDPOINT=
+S3_REGION=
+S3_ACCESS_KEY_ID=
+S3_SECRET_ACCESS_KEY=
+S3_BUCKET=
+```
+
+### Compatibilidade
+
+- O código atual espera um provider com API compatível com S3 e suporte a `PutObject`, `GetObject`, `HeadObject`, `DeleteObject` e URLs pré-assinadas.
+- A implementação usa `endpoint` customizado e `forcePathStyle: true` em [`src/shared/lib/storage/s3-client.ts`](/home/ubuntu/github/openmonetis/src/shared/lib/storage/s3-client.ts).
+- Em geral isso cobre MinIO, Cloudflare R2, Backblaze B2 S3-Compatible, DigitalOcean Spaces e AWS S3. Mas foi testado apenas no Supabase Storage.
+- Se o seu provider exigir `virtual-hosted-style` em vez de `path-style`, você vai precisar ajustar essa configuração antes de usar anexos.
+- Se as variáveis de S3 não forem configuradas, mantenha os anexos desabilitados no seu fluxo de uso.
