Month 2025-10: Focused on cross-platform CLI reliability. Delivered a bug fix by updating binary assets to correct executable permissions for preprocessor binaries in the CLI scheduling flow, across macOS ARM64 and Windows x86_64. No code changes were required; change is isolated to binary assets. This reduces runtime failures and improves deployment stability for end users and CI pipelines.

In 2025-08, two major feature enhancements were delivered for dcloudio/uni-app: built-in component recognition with iOS native tag handling improvements, and native ad styling integration. The iOS adjustments refine compilation by distinguishing built-in vs. custom components and excluding non-native items (e.g., navigator, slider) while expanding support for additional custom elements on iOS. The ad styling work adds a CSS file to ensure the ad container fills its parent, delivering a more seamless visual integration. Together, these changes reduce cross-platform inconsistencies, improve build reliability, and enhance end-user UX for native ads.
