🌟 Release Highlights

v0.79.4 delivers significant improvements to AI credit (AIC) cost tracking and telemetry accuracy, introduces new workflow authoring controls for custom model pricing and configurable timeouts, and hardens sandbox security. A focused round of bug fixes improves milestone caching, SHA-pinning reliability, and failure reporting.

⚠️ Breaking Changes

  • dangerously-disable-sandbox-agent now requires an operator-authored string justification (#38325). Boolean true is no longer accepted — workflows must supply a plain-text reason (≥ 20 characters) explaining why the trust boundary is being removed. Update any workflow using dangerously-disable-sandbox-agent: true to a descriptive string.

  • user-invokable and disable-model-invocation fields removed from the gh-aw schema (#38328). These Copilot-specific fields have no meaning in gh-aw workflows and will now produce a validation error. Remove them from any .github/workflows/*.md files.

✨ What's New

  • Custom model pricing via models frontmatter (#38276). Declare custom cost tables for private or non-catalog models directly in your workflow frontmatter. Overlays merge over the built-in models.json at runtime with main-workflow precedence. Learn more

  • Configurable safe-outputs timeout (#38361). The default safe_outputs job timeout has been raised from 30 to 45 minutes, and a new safe-outputs.timeout-minutes frontmatter field lets you tune it per workflow. Learn more

  • create_check_run now supports PR targeting (#38237). Pass target: "pr" or target: "*" to attach check runs to the triggering pull request in addition to the existing commit-based flow.

  • Steering messages visible in unified log view (#38277). Mid-run steering messages from operators are now rendered inline in the unified workflow log.

🐛 Bug Fixes & Improvements

  • AIC telemetry accuracy across all engines (#38314, #38364, #38327, #38412). The github_models provider alias is now recognised; zero-AIC firewall proxy responses correctly fall back to engine-reported values; AIC credits are properly wired through the agent failure handler and propagated into the failure footer.

  • Milestone cache now scoped per owner/repo (#38342). Milestone lookups in assign_milestone no longer bleed across repositories in multi-repo runs.

  • SHA-pinning for runtime setup-cli in custom steps: workflows (#38344). The emitted setup-cli step in steps: workflows now receives a SHA pin, aligning with the security posture of standard compiled workflows.

  • Failure-issue permission denials handled gracefully (#38273). Workflows lacking issues: write no longer crash on failure reporting; timeout-specific failure messages are now enforced separately.

  • Usage tracking fixed for engine jobs (#38353). sendJobConclusionSpan now correctly records token usage for engine-backed jobs.
