Unreleased

2.2.0 - 2026-08-25

Added

• Guided, manifest-driven setup across supported harnesses, with exact install-state ownership, health checks, repair, and uninstall workflows.
• Native Antigravity 2.0 installation under .agents/, including rules, workflows, skills, and adapted agents, plus a cross-platform installation guide.
• New workflow and operator capabilities including the Itô skill family, an experimental Nasiko CLI lifecycle bridge, multi-model council review, dev-team collaboration, agent evaluation, living-docs governance, secure terminal opening, and TasteForge multimodal workflows.
• A thin Pi adapter and expanded cross-harness support, release artifact lifecycle testing, Docker-based CLI testing, and stronger Python validation.

Changed

• Default MCP connector set reduced to a single connector (chrome-devtools) per the new connector policy (docs/MCP-CONNECTOR-POLICY.md). The six previous defaults (github, context7, exa, memory, playwright, sequential-thinking) were retired after the June 2026 audit: their jobs are covered by skills wrapping CLIs/REST APIs (github-ops, documentation-lookup, exa-search, e2e skills) or by harness-native features (memory, extended thinking, web search). All six remain opt-in via mcp-configs/mcp-servers.json.
• OpenCode home installs now use its canonical ~/.config/opencode location, safely discover and migrate unchanged ECC-managed files from legacy ~/.opencode installs, and preserve modified legacy files for review. Bundled agents inherit the model selected by the user instead of pinning an Anthropic provider.
• skill-comply is now part of the install manifest and npm distribution, with generated Python caches excluded from both install and package surfaces.
• Release automation now verifies the tag is exactly on origin/main, fails closed on npm registry errors, tests the exact packed artifact across Linux, macOS, and Windows, publishes stable versions to a staging dist-tag, verifies registry bytes before promoting latest, creates the GitHub Release after promotion, and uses reviewed release notes.

Fixed

• ecc memory writes and --body-file reads failed on Windows under Node 22.12-22.16 and 24.0-24.1. libuv resolved path-based stat()/lstat() through GetFileInformationByName without setting the volume serial, while fstat() reported it, so the memory vault's TOCTOU guard rejected every operation. Fixed upstream in libuv 1.51.0; the guard no longer depends on the runtime's patch level. The guard's stat calls now request BigInt values, so Windows file IDs past Number.MAX_SAFE_INTEGER can no longer collapse two distinct files into one identity.
• Selective reinstall now merges the prior ownership ledger, so later module additions do not orphan files from earlier installs and uninstall removes the complete managed surface.
• Legacy Codex sync uninstall now uses ownership evidence, preserves user files, and requires an explicit opt-in for weaker marker-only cleanup.
• The experimental Nasiko CLI lifecycle bridge now recovers locks only after confirming the recorded owner is dead, preserves replacement locks, strictly rejects malformed tar sizes, padding, terminators, and trailing data, and fails uninstall when staged files remain.
• Hook, plan-canvas, session, memory, observer, skill-evolution, Discord delivery, and Windows compatibility regressions fixed across the runtime.

Release audit

• Audited the complete delta from v2.1.0: 108 commits across 530 files, with 40,299 insertions and 4,679 deletions on the pre-release baseline.
• The release gate installs and exercises the exact npm archive, including cumulative ownership, doctor, drift detection, repair, uninstall, and user-file preservation.

2.0.0 - 2026-06-09

Added

• Discord community launch: server + GitHub PR/issue/release feed, release-announce.yml workflow (announce + pin + Discussions cross-post), and a dependency-free community bot (scripts/discord/ecc-bot.mjs) with /ecc, /help, /skill, /docs, /release.
• orch-* orchestrator skill family and dynamic workflow team orchestration.
• kubernetes-patterns skill, worktree-lifecycle service, MCP inventory (ecc.mcp.v1), codex-worktree and opencode session adapters.

Fixed

• Plugin hooks silently no-oped on Node 21+ (require.main undefined under node -e).
• Windows reliability: CLAUDE_PLUGIN_ROOT normalization, stdin prompt passing, symlink/chmod test guards.
• Session-end $-sequence corruption, project-detect boundary matching, install manifest gaps, corrupted legacy shim truncation.

Changed

• Version graduated to 2.0.0 stable across package, plugin, marketplace, OpenCode, and agent metadata.
• Smaller default OpenCode install surface; rules/zh removed from the always-loaded default install.

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.
