 ## [Unreleased]
 
+## [3.34.3] - 2026-03-11
+
+### Added
+
+- **MCP Server v1.1.0**: 4 new tools for tracking official Anthropic Claude Code docs
+  - `init_official_docs()` — fetch and store a local baseline snapshot (runs once)
+  - `refresh_official_docs()` — update the "current" snapshot without touching the baseline
+  - `diff_official_docs()` — compare baseline vs current at section level, zero network calls
+  - `search_official_docs(query)` — search official docs, loads only matching sections
+- **Local cache architecture**: 4 files in `~/.cache/claude-code-guide/` (index + content, baseline + current). Diff reads only lightweight index files (~50KB), never the full 1.2MB doc. Atomic writes via `.tmp` + rename to prevent corruption.
+
