Oct 1, 2025October 2025 (Month: 2025-10) – Developer-focused monthly summary for BCSDLab/KOIN_ANDROID. Key delivery includes a comprehensive Developer Settings Module (data store, local data source, repository, use cases) plus a dedicated Developer Settings page, enabling config-driven experimentation and faster feature iteration. The DI architecture was reworked around Koin plugins: introduced findPlugin usage, merged koin-compose into koin-application, and added a koin-feature module to simplify feature-scoped DI and testing. UI and tooling were modernized with Material3 as default and Compose Compiler support, aligning with the latest UI patterns and build tooling. Store sprint support was added via Sprint Settings UI, including logic to hide legacy store menus when sprint mode is enabled. A broad set of tooling upgrades and quality improvements were completed (Kotlin, KSP, Hilt; Gradle/AGP updates; documentation updates; code quality improvements). A comprehensive set of bug fixes improved stability and user experience across data binding, review flows, navigation, insets handling, error handling, and build/merge hygiene. Overall, the month delivered rapid, value-driven enhancements, improved developer experience, and a more robust, scalable foundation for next releases.
