v3.0

Release v3.0

Release Date: March 11, 2026

💥 Breaking Changes

Token Simplification

• copilot-token is now deprecated — the default github.token now supports copilot-requests permission natively. No PAT needed.
• If you were passing copilot-token: ${{ secrets.COPILOT_TOKEN }}, you can remove it entirely.

🐛 Bug Fixes

• copilot-config was never applied — the config input was accepted but never written to ~/.copilot/config.json. Now properly applied before every run.
• MCP config path used $XDG_CONFIG_HOME which may not be set on all runners — switched to $HOME/.copilot/ for consistency.
• Artifact name collisions when using the action in multiple jobs within the same workflow — artifact names now include github.job.

---

🛠️ Improvements

• copilot-config is now written to ~/.copilot/config.json so CLI settings like banner, theme, and render_markdown are respected.
• Session share files (copilot-session-*.md) are now included in the uploaded artifact.
• 15-job CI test matrix covering every input: basic, autopilot, silent, model, json-output, denied-tools, github-mcp, no-builtin-mcps, url-controls, share, experimental, additional-dirs, agent, fail-on-error, and config.

v2.0

🚀 Release v2.0

Release Date: November 28, 2025

💥 Breaking Changes

Token Configuration Overhaul

• github-token → copilot-token (renamed & now required)

  • The action now requires an explicit PAT with "Copilot Requests" permission
  • The default github.token does NOT have Copilot access — you must provide a PAT

• New repo-token input for separation of concerns

  • Use copilot-token for Copilot API access
  • Use repo-token for standard GitHub operations (push, PRs, etc.)
  • Defaults to github.token if not specified

MCP Configuration Changes

• MCP config no longer pre-configures GitHub MCP server by default
  • In v1.0, the GitHub MCP server was always injected into your config
  • In v2.0, you must explicitly configure MCP servers or use enable-all-github-mcp-tools: true
  • This gives users full control over their MCP setup
