v2.0.1 - "Patch Stability & Automation Fixes"

Arbor v2.0.1 Release Notes — "Patch Stability & Automation Fixes"

Theme: Fast, low-risk patch release to stabilize release automation and PR-impact reporting after v2.0.0.

Release date: April 20, 2026

---

Highlights

• PR Bot command path fixed

  • Switched from invalid subcommand path to real CLI-driven report generation via:
    • arbor diff . --json
  • Added PR commit-range awareness using ARBOR_DIFF_BASE and ARBOR_DIFF_HEAD.

• PR comment rendering fixed

  • JSON report output now renders as proper fenced Markdown in PR comments.

• Regression protection added

  • Added integration test coverage for ranged diff behavior in arbor-cli so commit-range reporting does not regress.

• Contributors automation hardened

  • contributors.yml now skips PR creation if contributor block is unchanged.
  • Uses github.token consistently in checkout/PR creation path.
  • Contributors script now uses Bearer auth and handles transient GitHub API failures gracefully.

---
