Allison summarizes the November 2025 GitHub Actions updates, including expanded reusable workflow limits, new M2 macOS runner support, and improved integration for the GitHub Copilot coding agent.

GitHub Actions November 2025 Releases: Increased Limits, M2 Runners, and Copilot Agent Update

Increased Limits for Reusable Workflows

Reusable Workflow Expansion: You can now nest up to 10 reusable workflows and call up to 50 workflows from a single workflow run. (Previous limits were 4 and 20, respectively.)
Impact: Enables larger-scale automation scenarios and facilitates improved collaboration across development teams.

M2 macOS Runners Generally Available

New Hardware: M2-powered macOS runners are now available. Use the labels macos-latest-xlarge, macos-15-xlarge, macos-14-xlarge, or macos-13-xlarge to schedule jobs on these runners.
Benefits: Gain improved performance metrics and GPU acceleration, useful for workflows that require higher compute or graphics capabilities.

Copilot Coding Agent Requirement Change

Simplified Setup: GitHub Copilot’s coding agent no longer requires GitHub Actions to be enabled for your organization.
Advantage: Easier access and more flexible integration of Copilot’s AI-powered coding features into repositories, boosting developer productivity.
