Apr 1, 2025April 2025 monthly summary for microsoft/graphitation: Delivered a consolidation of TypeScript input types into models.interface.ts for codegen, simplifying the generated output and improving consistency across the codegen surface. The change reduces fragmentation by emitting input types within models.interface.ts instead of a separate inputs.interface.ts, enabling easier maintenance and faster onboarding for contributors. No customer-facing downtime or regressions were observed; downstream consumers remain unaffected.
