+### Added
+
+- **Agent-agnostic canonical layout**: All command prompts now live in `.documentation/commands/` as the single source of truth. Platform directories (`.claude/`, `.github/`, `.cursor/`, etc.) contain only thin shims that redirect to canonical content with user-override resolution.
+- **Multi-user personalization**: New `/speckit.personalize` command creates per-user prompt overrides in `.documentation/{git-user}/commands/`. Users can customize any command without affecting team defaults; personalized files are committed to git for transparency.
+- **Personalize command template**: `templates/commands/personalize.md` — resolves git user identity, copies and annotates shared prompts for individual customization.
+
+### Changed
+
+- **Build scripts updated for canonical + shim architecture**: Both `create-release-packages.sh` and `create-release-packages.ps1` now generate canonical commands in `.documentation/commands/` and thin platform shims in agent-specific directories, replacing the previous approach of duplicating full prompts per agent.
+- **Documentation refresh**: Updated README.md, AGENTS.md, spec-driven.md, FORK_DIVERGENCE.md, CONTRIBUTING.md, release_notes.md, and all GitHub Pages site docs (index.md, quickstart.md, installation.md, adaptive-lifecycle.md, roadmap.md) to consistently emphasize three pillars: agent-agnostic architecture, multi-user personalization, and full lifecycle coverage.
+- **Version bump**: 1.5.1 → 1.6.0.

 ## Release Highlights
 
-This release (v1.5.0) introduces the new `/speckit.repo-story` command for generating evidence-based repository narratives, completes a branding alignment sweep, and syncs the README roadmap version with the actual CLI version.
+This release (v1.6.0) introduces agent-agnostic canonical layout, multi-user personalization, and a comprehensive documentation refresh emphasizing Spec Kit's three pillars.
 
-### What's New in v1.5.0
+### What's New in v1.6.0
 
-- **`/speckit.repo-story` Command**: Analyze full commit history and produce compelling narratives for business and technical audiences
-- **Repository History Context Scripts**: Paired Bash and PowerShell scripts generating commit-audit-ready JSON with anonymized roles, velocity metrics, quality signals, and governance maturity scores
-- **Branding Alignment**: Consistent "Spec Kit Spark — ASLCD Toolkit" messaging across all documentation, CLI, and release generators
-- **Version Sync**: README roadmap updated from stale v0.0.25 to v1.5.0
+- **Agent-Agnostic Canonical Layout**: Command prompts now live in `.documentation/commands/` as a single source of truth. Platform directories (`.claude/`, `.github/`, `.cursor/`, etc.) contain only thin shims that redirect to canonical content with user-override resolution. Switch agents freely or use multiple agents on the same project.
+- **Multi-User Personalization**: New `/speckit.personalize` command creates per-user prompt overrides in `.documentation/{git-user}/commands/`. Customize any command without affecting team defaults — personalized files are committed to git for team transparency.
+- **Three Pillars Documentation**: All repository and site documentation updated to consistently communicate agent-agnostic architecture, multi-user personalization, and full lifecycle coverage as the three reinforcing design pillars.
