 # Changelog
 
+## 2025-11-17 - 2.7.2 - fix(compilerOptions)
+Remove experimentalDecorators and useDefineForClassFields from default TypeScript compiler options
+
+- Removed experimentalDecorators from compilerOptionsDefault in ts/tsbuild.classes.tsbuild.ts
+- Removed useDefineForClassFields from compilerOptionsDefault in ts/tsbuild.classes.tsbuild.ts
+- Default compiler options now rely on TypeScript's upstream defaults for decorator and class field behavior
+- If your project relies on these settings, re-enable them in your tsconfig.json or pass them via the programmatic API / CLI
+
 ## 2025-11-02 - 2.7.1 - fix(readme)
 Update documentation: expand README with usage, CLI and API examples; add readme.hints.md project memory
