 # Changelog
 
+## 2025-10-23 - 5.1.2 - fix(scripts)
+Add build script to package.json and include local dev tool settings
+
+- Add a 'build' script to package.json (no-op placeholder) to provide an explicit build step
+- Minor scripts section formatting tidy in package.json
+- Add a hidden local settings file for development tooling permissions to the repository (local-only configuration)
+
+## 2025-10-23 - 5.1.1 - fix(tooling)
+Add .claude/settings.local.json with local automation permissions
+
+- Add .claude/settings.local.json to specify allowed permissions for local automated tasks
+- Grants permissions for various developer/CI actions (deno check/lint/fmt, npm/npm pack, selective Bash commands, WebFetch to docs.deno.com and code.foss.global, and file/read/replace helpers)
+- This is a developer/local tooling config only and does not change runtime code or package behavior
+
+## 2025-10-22 - 5.1.0 - feat(packaging)
+Add npm packaging and installer: wrapper, postinstall downloader, publish workflow, and packaging files
+
+- Add package.json (v5.0.5) and npm packaging metadata to publish @serve.zone/nupst
+- Include a small Node.js wrapper (bin/nupst-wrapper.js) to execute platform-specific precompiled binaries
+- Add postinstall script (scripts/install-binary.js) that downloads the correct binary for the current platform and sets executable permissions
+- Add GitHub Actions workflow (.github/workflows/npm-publish.yml) to build binaries, pack and publish to npm, and create releases
+- Add .npmignore to keep source, tests and dev files out of npm package; keep only runtime installer and wrapper
+- Move example action script into docs (docs/example-action.sh) and remove the top-level example-action.sh
+- Include generated npm package artifact (serve.zone-nupst-5.0.5.tgz) and npmextra.json
+
 ## 2025-10-18 - 4.0.0 - BREAKING CHANGE(core): Complete migration to Deno runtime
 
 **MAJOR RELEASE: NUPST v4.0 is a complete rewrite powered by Deno**
