October 2025: Angular compiler diagnostic improvement for missingStructuralDirective. Implemented refined detection to catch missing imports for structural directives, including scenarios with multiple directives on the same element; this reduces false negatives and improves build reliability and developer feedback during compilation.

September 2025 monthly summary for prettier/angular-html-parser: Focused on stand-alone migration improvements and ensuring robust import alias handling across modules.
