July 2025 monthly summary for jmix-framework/jmix: Delivered a focused combination of a feature and multiple stability/enhancement fixes that improve onboarding, UX, and system reliability. The project templates now default to a streamlined PWA configuration by removing the @PWA annotation, reducing setup effort for new projects. UI reliability and developer feedback improved through targeted bug fixes: stable DataGrid focus, corrected FileUpload hover visuals, deterministic role name sorting, and improved error handling in many-to-many attribute generation. These changes reduce misconfigurations, lower support load, and accelerate time-to-value for customers. Technologies demonstrated include Java/Kotlin template updates, JavaScript-based UI focus workarounds, code refactoring for reliability, and enhanced logging for misconfigurations.
