 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [0.1.2] — 2026-04-26
+
+First version published to npm. Pre-publish polish only — no behaviour change beyond what 0.1.1 already shipped.
+
+### Build / Release
+
+- Added CI workflow (typecheck + build matrix on Node 18/20/22) and a Release workflow that, on `v*` tag push, verifies the tag matches `package.json`, builds, and runs `npm publish --access public --provenance` (sigstore attestation), then cuts a GitHub Release using the matching CHANGELOG section as the notes.
+- `main` is now branch-protected: PR + CI required, no force push, no delete, linear history.
+
+### Metadata
+
+- Tightened `description` so the high-value search terms (Google Play, MCP, Android Publisher API, Play Developer Reporting) fit inside the first 150 characters npm shows in search results.
+- `keywords`: added `mcp-server`, `cursor`, `vscode`, `codex`, `gemini-cli`, `windsurf`, `play-developer-api`, `play-developer-reporting`, `play-purchases`, `monetization`, `agentic`, `ai-assistant`, `automation`, `android-app`. Removed `llm` (too generic).
+- README: added `npm version`, `npm downloads`, `CI`, `Tools: 150`, and `TypeScript-strict` badges.
+
 ## [0.1.1] — 2026-04-26
 
 Bug fix for the Play monetization catalog endpoints.
