+## 2025-11-17 - 3.0.0 - BREAKING CHANGE(TsBuild)
+Stop forcing emitDecoratorMetadata in protected compiler defaults
+
+- Removed emitDecoratorMetadata from the set of protected/critical default compiler options.
+- Projects that relied on tsbuild automatically enabling emitDecoratorMetadata (for DI frameworks like NestJS, TypeORM, Inversify) must now enable it explicitly in their tsconfig.json or via programmatic/CLI options.
+- No other protected defaults were changed; outDir, noEmitOnError, declaration and inlineSourceMap remain enforced.
+- Behavior is now more permissive: decorator metadata generation is controlled by user configuration rather than being forced by tsbuild.
+
 ## 2025-11-17 - 2.7.3 - fix(tsbuild.classes)
 Remove duplicate emitDecoratorMetadata from default compiler options and centralize it in protected defaults
