Worked on enhancing release automation reliability for the espressif/qemu repository by refining the make-release script to ensure deterministic behavior across different environments. Addressed a bug where subproject directory exclusions were previously computed from the current working directory, updating the script to reference the source directory instead. This adjustment eliminated path resolution discrepancies and reduced release-time failures. Improved error handling by leveraging standard shell commands for clearer, actionable error messages during release builds. Utilized Shell scripting and build systems expertise to increase maintainability and robustness of the release process, focusing on scripting best practices and automation reliability throughout the development cycle.
