Letos 4.0.2

Letos 是一款專為 macOS 設計的 SQLite 資料庫管理工具，前身是 SQLiteStudio for Mac，特色是免安裝、單一執行檔即可執行，介面直覺好上手。它近期將原始碼與問題追蹤遷移到 GitHub，有助於社群協作與回報，開發上仍維持活躍更新。雖然評分人數不多，但使用者評價普遍不錯，在同類工具中屬於小眾但可靠的選擇。

這套軟體適合需要輕量管理 SQLite 資料庫的開發者或進階使用者，特別是偏好可攜帶、不想安裝額外環境的場合。與 Microsoft Access 或 Parallels Desktop 等大型方案相比，它專注於 SQLite 單一資料庫，功能相對單純，取捨是少了進階整合與圖表功能，但換來輕巧與快速啟動。授權為開源軟體，目前僅提供英文介面，使用前需留意語系支援，且僅有 macOS 版本（另有 Windows 版可參考）。

Letos for Mac (formerly SQLiteStudio for Mac) is an advanced SQLite database manager for macOS with an intuitive user interface, with no installation needed (single executable file to run).

Letos for macOS has recently migrated to GitHub. This affects the source code repository, as well as the issue tracker (bugs & feature requests).

This should improve collaboration with potential contributors and also make it more readable, as GitHub has a well-established platform for the same. All bug reports from the old tracker have been migrated to GitHub.
