January 2025: Executed a cross-repo CI/CD modernization and dependency refresh across the Uno Platform ecosystem, delivering consistent versioning, updated platform dependencies, and improved release reliability. Migration from GitVersion to Next-Based Git Versioner (NBGV) completed in key repositories, enabling automated, platform-wide versioning with legacy-branch support and streamlined CI workflows. Upgraded major Uno packages (e.g., Uno.UI, Uno.WinUI, Uno.Extensions, Uno.Material, Uno.Cupertino, etc.) to latest stable versions to incorporate features, fixes, and stability improvements, reducing risk and improving compatibility for downstream apps. Key platform improvements include Wasm net8.0 resource embedding and browser logger adjustments for Wasm contexts, unified versioning tooling across CI and Uno SDK update workflows, and improved resource handling performance (ResourceDictionary lazy initialization and not-found caching) along with a broad set of UI/resource bug fixes. Performance improvements were extended to WebAssembly and animation parsing, with reliability enhancements for HR workspace loading. Android platform compatibility adjustments were applied for broader device coverage. Documentation updates reflecting HR logging and CI changes were completed. Additional maintenance occurred in Uno.Gallery and Uno.Check to keep dependencies current and CI commands correct. Impact: Reduced build fragility and release friction, faster and more predictable software deliveries across platforms, improved runtime performance and diagnostics in WebAssembly UIs, and stronger cross-repo consistency for versioning and dependency management.

October 2024: Stabilized application startup by correcting command-line argument handling in uno.extensions. The executable path (argv[0]) is now excluded from the remaining CLI arguments passed to the ApplicationBuilder, eliminating startup failures caused by invalid arguments. Implemented as a focused fix under commit a263cee6ef61615c5212cf04d8dc3a677116518a. This change increases reliability for UNO Platform apps and reduces support risk by ensuring startup flows are robust and predictable.
