+# Canopy CLI / MCP — Changelog
+
+Tracks the Python side (CLI + MCP server). The VSCode extension has its own [vscode-extension/CHANGELOG.md](vscode-extension/CHANGELOG.md).
+
+Versions follow semver. Pre-1.0 — minor bumps may add features or break behavior; the README is the source-of-truth contract.
+
+## 0.5.0
+
+Catches the `__version__` constant up to ~6 months of shipped milestones (0.1.0 → 0.5.0). The handshake the doctor's `cli_stale` / `mcp_stale` checks rely on is only useful when the source-of-truth version actually moves — this release fixes that.
+
+### New since 0.1.0
+
+- **Wave 2.3 — `commit` + `push`** (PR #2 + #3): feature-scoped multi-repo commit and push with `wrong_branch` / `no_upstream` blockers and per-repo result classification.
+- **M0 — Provider injection architecture** (PR #7): `docs/architecture/providers.md` design doc for the issue-provider contract.
+- **M1 — `canopy doctor`** (PR #8): single recovery primitive with 16 diagnostic categories (state-file integrity + install / version / mcp / skill / vsix). `--fix` for auto-repairable; severity tiers; structured JSON.
+- **M5 — Issue-provider scaffold** (PR #9): `IssueProvider` Protocol + registry under `canopy.providers.*`. Linear refactored into the contract; new `GitHubIssuesProvider` via `gh` CLI. `[issue_provider]` block in canopy.toml; `issue_get` / `issue_list_my_issues` MCP tools (deprecated `linear_*` aliases retained).
+- **M2 — Augments** (PR #10): per-workspace `[augments]` block in canopy.toml + per-repo overrides. `preflight_cmd` is the first consumer; `review_bots` and `test_cmd` reserved. Multi-skill installer (`canopy setup-agent --skill augment-canopy`); `augment-canopy` skill teaches the agent how to mutate canopy.toml safely.
+- **M3 — Bot-comment tracking** (PR #12): per-comment resolution log at `.canopy/state/bot_resolutions.json`; `canopy commit --address <comment-id>` auto-suffixes the message + records the resolution; `canopy bot-status` rollup; new `awaiting_bot_resolution` state in the state machine; `actionable_count` split into human + bot counts.
+- **M4 — Historian** (PR #14): per-feature persistent memory at `.canopy/memory/<feature>.md`. Auto-read on `canopy switch` (response carries `memory: <markdown>`); 5 MCP tools (`historian_decide` / `historian_pause` / `historian_defer_comment` / `feature_memory` / `historian_compact`); 2 CLI commands (`canopy historian show` / `compact`); auto-mirror from `commit --address` and `github_get_pr_comments`.
+
+### Counts
+
+- MCP tools: 41 → 54
+- Test suite: ~400 → 624 passing
+- State machine: 8 states → 9 states (added `awaiting_bot_resolution`)
+- Bundled skills: 1 (`using-canopy`) → 2 (+ opt-in `augment-canopy`)
+
+## 0.1.0
+
+Initial release. Wave 1 + Wave 2.1/2.2: workspace discovery, feature lanes, post-checkout hook, drift detection, switch/triage/feature_state actions, MCP server, agent setup.

 - **Worktree limits:** `max_worktrees` in canopy.toml caps explicit `worktree_create` calls (`WorktreeLimitError` includes stale candidates). For `switch`'s canonical-slot logic, the same field is interpreted as the warm-slot cap; if unset (0), the new default is **2** (1 canonical + 2 warm = 3 live trees max). See `actions/switch_preflight.py:warm_slot_cap`.
 - **Action contract:** `actions/protocol.py` (planned) will formalize the per-repo `{status, before, after, reason?}` shape. For now, each action returns it ad-hoc.
 - **Skill bundling:** Bundled skills live at `src/canopy/agent_setup/skills/<name>/SKILL.md`. `canopy setup-agent` copies them to `~/.claude/skills/<name>/SKILL.md`. The default `using-canopy` skill always installs; opt-in extras (e.g. `augment-canopy`) install via `--skill <name>` (repeatable). Foreign skills with the same path are not overwritten without `--reinstall`. The `_SKILL_SOURCE` constant remains as a backward-compat alias pointing at `using-canopy`'s source.
+- **Version bumps:** When shipping a milestone, bump `__version__` in [`src/canopy/__init__.py`](src/canopy/__init__.py) and add a section to [`CHANGELOG.md`](CHANGELOG.md). The version handshake (`canopy --version`, `mcp__canopy__version`, doctor's `cli_stale` / `mcp_stale` checks) is only useful when this number actually moves — drift was the bug 0.5.0 caught.
