🌟 Release Highlights

This release focuses on hardening the sandbox and MCP gateway, smoothing out safe-output and threat-detection reliability, and shipping a steady stream of security and quality fixes across the compiler and CLI.

✨ What's New

  • Docker sandbox (docker-sbx) rollout continues — the sandboxed execution environment now runs for a larger share of agentic workflows, with fixes for pre-flight step naming, gVisor false positives, and Docker Hub secret handling (#51264, #51294, #51341, #51439, #51949). See the sandbox reference.
  • Agent runtime trackingsandbox.agent.runtime is now stored in aw_info.json, and gh aw logs/gh aw audit gained a --runtime filter for easier debugging across engines (#51465, #52076). See agent runtimes.
  • MCP gateway hardening — explicit mount policy allowlisting for the safeoutputs backend server, plus a bump to gh-aw-mcpg v0.4.9 and github-mcp-server v1.9.0 (#51870, #51828).
  • Skills frontmatter flexibility — non-SHA refs are now allowed in skills frontmatter and pinned automatically at compile time, and an explicit end-marker syntax was added for inline skills/sub-agents (#51455, #51446).
  • Threat detection improvements — inline threat detection for Code Scanning Fixer, rendered detection logs with group/mask macros, and gh-aw's own <system> prompt block is no longer flagged as prompt injection (#51277, #51255, #51818). See threat detection.

🐛 Bug Fixes & Improvements

  • Fixed silent failures in the Copilot session data fetcher and in gh aw mcp inspect pagination (#51195, #51193).
  • Fixed Claude harness retrying invalid-JSON body errors with --continue instead of starting a fresh run (#51793).
  • Fixed a CGO/CJS workflow cache key collision that caused widespread job failures (#51342).
  • Fixed recurring gh-aw-firewall digest-pin loss on default firewall version bumps (#51423).
  • Fixed Windows MCP server timeouts by propagating context through GitHub CLI subprocess calls (#51426).
  • Fixed retry handling and denials in the Contribution Check proxy (#51631).
  • Added support for HEAD-only bundles when pushing to pull request branches (#51833).
  • Fixed safe-output run summary classification so entries are always linked and correctly attributed (#51484, #51478).

📚 Documentation

  • Documented the --runtime flag for gh aw logs/gh aw audit, agent runtime selection/troubleshooting, and clarified Claude engine selection in automated bootstrap (#52076, #51427, #52099).
  • Improved overall documentation discoverability and trimmed troubleshooting guides (#52065, #51251).

🔧 Internal

A large batch of custom-linter hardening, dependency bumps, test-parallelization, and dependency vulnerability remediations (container image pinning, ip-address patch, deprecated MCP container replacements) round out this release — thanks to the automated maintenance workflows keeping the codebase clean and secure.> Generated by 🚀 Release · auto · 20.7 AIC · ⊞ 11.3K
