# Changelog

## 2.0.0-rc.1 - 2026-04-28

### Highlights

- Adds the public ECC 2.0 release-candidate surface for the Hermes operator story.
- Documents ECC as the reusable cross-harness substrate across Claude Code, Codex, Cursor, OpenCode, and Gemini.
- Adds a sanitized Hermes import skill surface instead of publishing private operator state.

### Release Surface

- Updated package, plugin, marketplace, OpenCode, agent, and README metadata to `2.0.0-rc.1`.
- Added `docs/releases/2.0.0-rc.1/` with release notes, social drafts, launch checklist, handoff notes, and demo prompts.
- Added `docs/architecture/cross-harness.md` and regression coverage for the ECC/Hermes boundary.
- Kept `ecc2/` versioning independent for now; it remains an alpha control-plane scaffold unless release engineering decides otherwise.

### Notes

- This is a release candidate, not a GA claim for the full ECC 2.0 control-plane roadmap.
- Prerelease npm publishing should use the `next` dist-tag unless release engineering explicitly chooses otherwise.

## 1.10.0 - 2026-04-05

### Highlights

- Public release surface synced to the live repo after multiple weeks of OSS growth and backlog merges.
- Operator workflow lane expanded with voice, graph-ranking, billing, workspace, and outbound skills.
- Media generation lane expanded with Manim and Remotion-first launch tooling.
- ECC 2.0 alpha control-plane binary now builds locally from `ecc2/` and exposes the first usable CLI/TUI surface.

### Release Surface

- Updated plugin, marketplace, Codex, OpenCode, and agent metadata to `1.10.0`.
- Synced published counts to the live OSS surface: 38 agents, 156 skills, 72 commands.
- Refreshed top-level install-facing docs and marketplace descriptions to match current repo state.

### New Workflow Lanes

- `brand-voice` — canonical source-derived writing-style system.
- `social-graph-ranker` — weighted warm-intro graph ranking primitive.
- `connections-optimizer` — network pruning/addition workflow on top of graph ranking.
- `customer-billing-ops`, `google-workspace-ops`, `project-flow-ops`, `workspace-surface-audit`.
- `manim-video`, `remotion-video-creation`, `nestjs-patterns`.

### ECC 2.0 Alpha

- `cargo build --manifest-path ecc2/Cargo.toml` passes on the repository baseline.
- `ecc-tui` currently exposes `dashboard`, `start`, `sessions`, `status`, `stop`, `resume`, and `daemon`.
- The alpha is real and usable for local experimentation, but the broader control-plane roadmap remains incomplete and should not be treated as GA.

### Notes

- The Claude plugin remains limited by platform-level rules distribution constraints; the selective install / OSS path is still the most reliable full install.
- This release is a repo-surface correction and ecosystem sync, not a claim that the full ECC 2.0 roadmap is complete.

## 1.9.0 - 2026-03-20

- 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.
