Zhang Tianhao updated the Ads-Global-M library to version 7.5.6.0 in the CocoaPods/Specs repository, focusing on dependency management and repository hygiene. He replaced the existing pod directory with the new release, ensuring downstream developers could access the latest features and bug fixes. This work involved two traceable commits, one for removing the outdated directory and another for adding the updated version, which improved compatibility and reduced build issues for projects relying on Ads-Global-M. Zhang utilized Ruby and CocoaPods to streamline dependency resolution, demonstrating careful version control and enabling faster adoption of updates across the developer ecosystem.
