🌟 Release Highlights

This release focuses on security hardening, GHES compatibility, and developer experience improvements — with better MCP write protection, a new Copilot pre-flight diagnostic for enterprise environments, and a noticeably improved run details summary.

✨ What's New

  • MCP Write-Sink Guard Policy — All non-GitHub MCP servers configured via the gateway now enforce a write-sink guard policy, preventing unintended writes through third-party MCP tools. This improves the security posture of workflows using custom MCP integrations. (#21005)

  • Copilot Pre-flight Diagnostic for GHES — A new pre-flight check helps diagnose Copilot configuration issues in GitHub Enterprise Server environments before a workflow run fails, saving time when debugging enterprise setups. (#20975)

  • Action Pins Mode with gh-aw-actions v0 — The action-tag step now uses action pins mode, enabling stable and auditable action references via gh-aw-actions at the v0 tag. (#20991)

  • Enhanced Run Details Step Summary — Workflow run summaries now render as structured bullet points, display the gh-aw version, and include full aw_info output for easier post-run inspection. (#20989)

⚡ Performance

  • Faster Workflow Name Extraction — extractWorkflowNameFromFile no longer performs an unnecessary full YAML parse, reducing overhead when processing large workflow collections. (#21012)

🐛 Bug Fixes & Improvements

  • GHES Host Leakage Prevention — The "Install GitHub Copilot CLI" step now explicitly emits GH_HOST: github.com, preventing GHES host values from leaking into the Copilot CLI installation context. (#20992)
  • Workflow Call Artifact Downloads Fixed — Artifact prefix handling in the conclusion job and script step downloads now works correctly in workflow_call contexts. (#21011)
  • TypeScript Type Error Fixed — Resolved a type error in json_object_to_markdown.cjs that could cause runtime failures in certain output scenarios. (#21010)
  • Go Firewall Rule for Shared Workflows — The shared/go-make.md shared workflow now includes go in its firewall allowed set, enabling Go toolchain downloads during builds. (#21014)

📚 Documentation

  • Accessibility: Live Search Results — The docs site search now announces results to screen readers via aria-live, improving accessibility for keyboard and assistive technology users. (#21019)
