 StackMemory is a **production-ready memory runtime** for AI coding tools that preserves full project context across sessions. With **Phases 1-4 complete**, it delivers:
 
 - ✅ **89-98% faster** task operations than manual tracking
-- ✅ **10,000+ frame depth** support with hierarchical organization  
+- ✅ **10,000+ frame depth** support with hierarchical organization
 - ✅ **Full Linear integration** with bidirectional sync
 - ✅ **20+ MCP tools** for Claude Code
 - ✅ **Context persistence** that survives /clear operations
 - ✅ **Two-tier storage system** with local tiers and infinite remote storage
 - ✅ **Smart compression** (LZ4/ZSTD) with 2.5-3.5x ratios
 - ✅ **Background migration** with configurable triggers
-- ✅ **296 tests passing** with improved error handling
-- ✅ **npm v0.3.16** published with production-ready improvements
+- ✅ **396 tests passing** with standardized error handling
+- ✅ **npm v0.5.29** published with WhatsApp notifications and improved integrations
 
 Instead of a linear chat log, StackMemory organizes memory as a **call stack** of scoped work (frames), with intelligent LLM-driven retrieval and team collaboration features.
