Developed and delivered a new Homebrew formula for OvertureMaps version 0.20.0, integrating it into the chenrui333/homebrew-core repository to streamline installation and management for Homebrew users. Focused on packaging automation and repository hygiene, the work leveraged Shell scripting, YAML configuration, and GitHub Actions to align with Homebrew’s CI/CD and DevOps best practices. By automating deployment and versioning, the update reduced manual setup time and ongoing support needs for users. No major bug fixes were addressed during this period, as the primary emphasis remained on feature delivery and ensuring stable, automated updates within the Homebrew ecosystem.
