v4.9.0
Catch-up release spanning 4.3.0 → 4.9.0 (public was last at 4.2.2).
Highlights
- build-workflow-v2 (experimental) — JS-orchestrated GREENFIELD + EDIT pipeline with hard-enforced gates (validate before push, drift-safe
push --verify, bounded fix-loops as control flow). 8 reusable agentTypes. - build-stack-v2 (experimental) — lifts v2 discipline to a whole workflow stack (orchestrator + Execute-Workflow sub-WFs), topological bottom-up build. Plus stack-intake guided interview for users new to n8n.
- mirror-sync — pulls every remote-only workflow so the repo mirrors the instance; auto-triggered by a SessionStart drift probe.
- Environment safety — one env per session (enforce-env PreToolUse gate, report-session-env); workflow subagents inherit
N8NAC_ENVIRONMENT. - Pattern skills — n8n-orchestration-patterns, n8n-structured-extraction.
- Feedback loop — SessionEnd auto-capture of NON-PII friction counts, redact-gated central sync.
- find-project, test-manual, idempotent CLAUDE.md section anchoring, workflow-reviewer 15-point design-quality checks.
