# Changelog

## 2.0.0 - 2026-04-01

### Highlights

- Public ECC 2.0 preview release surface aligned across root package metadata, docs, and release collateral.
- Hermes is now part of the public ECC story via a sanitized setup guide, generated-skills surface, and operator workflow documentation.
- Launch pack added for same-day rollout: release notes, X thread, LinkedIn post, article outline, launch checklist, and short-form video scripts.
- Repo version drift fixed between `package.json`, `package-lock.json`, `.opencode/package.json`, `AGENTS.md`, and `VERSION`.

### New Docs

- `docs/HERMES-SETUP.md` — sanitized public guide for running Hermes with ECC as the operator surface
- `docs/releases/2.0.0-preview/release-notes.md`
- `docs/releases/2.0.0-preview/x-thread.md`
- `docs/releases/2.0.0-preview/linkedin-post.md`
- `docs/releases/2.0.0-preview/video-shorts.md`
- `docs/releases/2.0.0-preview/article-outline.md`
- `docs/releases/2.0.0-preview/launch-checklist.md`

### Positioning

- ECC 2.0 is framed as a cross-harness operating system for agentic work, not only a Claude Code plugin.
- Hermes is positioned as the opinionated operator shell sitting on top of ECC skills, MCPs, hooks, crons, and workflow assets.
- The public preview intentionally ships the documented setup and launch assets first; additional private/local integrations can land incrementally.

## 1.9.0 - 2026-03-20

### Highlights

- Selective install architecture with manifest-driven pipeline and SQLite state store.
- Language coverage expanded to 10+ ecosystems with 6 new agents and language-specific rules.

## 1.8.0 - 2026-03-04

### Highlights

- Harness-first release focused on reliability, eval discipline, and autonomous loop operations.
- Hook runtime now supports profile-based control and targeted hook disabling.
- NanoClaw v2 adds model routing, skill hot-load, branching, search, compaction, export, and metrics.

### Core

- Added new commands: `/harness-audit`, `/loop-start`, `/loop-status`, `/quality-gate`, `/model-route`.
- Added new skills:
  - `agent-harness-construction`
  - `agentic-engineering`
  - `ralphinho-rfc-pipeline`
  - `ai-first-engineering`
  - `enterprise-agent-ops`
  - `nanoclaw-repl`
  - `continuous-agent-loop`
- Added new agents:
  - `harness-optimizer`
  - `loop-operator`

### Hook Reliability

- Fixed SessionStart root resolution with robust fallback search.
- Moved session summary persistence to `Stop` where transcript payload is available.
- Added quality-gate and cost-tracker hooks.
- Replaced fragile inline hook one-liners with dedicated script files.
- Added `ECC_HOOK_PROFILE` and `ECC_DISABLED_HOOKS` controls.

### Cross-Platform

- Improved Windows-safe path handling in doc warning logic.
- Hardened observer loop behavior to avoid non-interactive hangs.

### Notes

- `autonomous-loops` is kept as a compatibility alias for one release; `continuous-agent-loop` is the canonical name.
