GitHub Actions has introduced new features to enhance workflow management for pull requests (PRs) from repository forks, addressing concerns about privilege escalation in private repositories and improving automation for public repositories. The update includes three new settings for private repositories, allowing users to run workflows on forked PRs with proper permission controls at the enterprise, organization, and repository levels. For public repositories, a new `pull_request_target` event has been added, granting workflows access to read/write tokens and secrets by running them against the base of the PR, thereby enabling maintainers to safely automate tasks like labeling or commenting. Additionally, a new `workflow_run` event allows one workflow to trigger another upon completion, facilitating complex automation sequences and further analysis of continuous integration outcomes. These innovations aim to streamline processes, provide flexibility, and maintain security, with further details available in the GitHub documentation and community discussions.
