GitHub's new code owners feature enhances the code review process by allowing repository maintainers to specify which individuals or teams must review changes to specific files, thereby streamlining the review workflow and ensuring that knowledgeable reviewers are involved. This is achieved by creating a CODEOWNERS file in the repository, where file patterns are mapped to designated owners, who are automatically requested for review when a pull request affects their files. Additionally, a protected branch option can be enabled to require a review from code owners before merging, adding an extra layer of security and ensuring thorough evaluation of changes. This feature, inspired by Chromium’s OWNERS files, aims to improve the effectiveness of code reviews and invites user feedback for further enhancement.
