 ## [Unreleased]
 
+## [1.1.0] - 2026-06-18

 ### Added
-- **sys-medic agent**: Linux/Kubernetes node health assessment agent integrated as a standard kaizen-agentic infrastructure agent (KAIZEN-WP-0002 Part 1)
-- **Ecosystem integration (WP-0004)**: Helix Forge correlation (`metrics correlate`, `HELIX_SESSION_UID` env), artifact-store publish (`metrics publish`), activity-core ActivityDefinition references, integration patterns docs
-- **Community engagement (WP-0001 partial)**: `kaizen-agentic feedback` CLI, Gitea issue templates, `.gitea/workflows/ci.yml`, `.pre-commit-config.yaml`, `docs/FEEDBACK.md`, `docs/TELEMETRY.md`
-- **Project metrics convention (ADR-004)**: `.kaizen/metrics/<agent>/` storage via `MetricsStore` and `OptimizerStore`
-- **Metrics CLI**: `kaizen-agentic metrics record|show|list|export|optimize` for per-execution records and optimizer analysis
-- **Optimizer integration**: `OptimizationLoop.from_metrics_store()` wired to project metrics; `memory brief` includes `## Performance Summary`
-- **tdd-workflow metrics pilot**: Reference agent for measure → analyse → orient loop (`wiki/AboutKaizenAgents.md`)
-- **Packaged agents**: `coach`, `sys-medic`, `scope-analyst`, and `optimization` synced to `src/kaizen_agentic/data/agents/` (20 agents total)
+- **`kaizen-agentic feedback`** CLI and Gitea issue templates for developer feedback
+- **Gitea CI** (`.gitea/workflows/ci.yml`) — black + pytest on Python 3.10/3.12
+- **Pre-commit hooks** (`.pre-commit-config.yaml`) and `make pre-commit-install`
+- **`docs/FEEDBACK.md`** and **`docs/TELEMETRY.md`** (ADR-004 two-layer telemetry model)
+- **Ecosystem integration (WP-0004)**: Helix correlation, artifact-store publish, activity-core definitions
+- **Project metrics (WP-0003)**: ADR-004 storage, metrics CLI, optimizer wiring, tdd-workflow pilot
+- **sys-medic agent** and packaged fleet sync (20 agents in `data/agents/`)
+
+### Changed
+- **Lazy agent registry** — index by frontmatter name; parse on demand; path-based install copy
+- **CLI error messages** — clearer guidance when agents directory or package missing
+- **CONTRIBUTING.md** — post-pull reinstall instructions (`pip install -e .` / pipx)
+
+### Fixed
+- **Makefile template** in project initializer — tab characters no longer break Python linting
+- Removed stale `agents_backup_*/` scaffolding from development installs
