-**BREAKING CHANGES - Please Read:**
+Upgrades are automatic when updating via the plugin marketplace. Key changes in recent versions:
 
-v4.0.0 introduces breaking changes:
+**v7.1.0**: PM2 replaced with native Bun process management. Migration is automatic on first hook trigger.
 
-- **Data Location Changed**: Database moved from `~/.claude-mem/` to `${CLAUDE_PLUGIN_ROOT}/data/` (inside plugin directory)
-- **Fresh Start Required**: No automatic migration from v3.x. You must start with a clean database
-- **Worker Auto-Starts**: Worker service now starts automatically - no manual `npm run worker:start` needed
-- **MCP Search Server**: 7 new search tools with full-text search and citations
-- **Enhanced Architecture**: Improved plugin integration and data organization
+**v7.0.0+**: 11 configuration settings, dual-tag privacy system.
 
-See [CHANGELOG](https://github.com/thedotmack/claude-mem/blob/main/CHANGELOG.md) for complete details.
+**v5.4.0+**: Skill-based search replaces MCP tools, saving ~2,250 tokens per session.
