 # Changelog
 
+## 2026-03-06 - 4.3.0 - feat(mod_logger)
+add centralized TsBuildLogger and replace ad-hoc console output with structured, colored logging
+
+- Add ts/mod_logger/classes.logger.ts providing header/step/detail/success/error/warn/indent utilities with ANSI color support
+- Export logger from ts/mod_logger/index.ts and re-export from ts/index.ts
+- Replace console.log/console.error/console.warn calls in mod_cli, mod_compiler, and mod_unpack with TsBuildLogger methods for consistent, hierarchical output
+- Refactor error-summary, emit and type-check output to use logger separators, colors, and structured messages
+
 ## 2026-03-05 - 4.2.6 - fix(meta)
