-> - 🔄 Codex resume mechanism (`codex exec "..." resume --last`) for context continuity
-> - 📋 TodoWrite progress tracking for subtask execution
-> - 📚 Streamlined CLI documentation (60% reduction in redundancy)
-> - 🔧 Enhanced Codex agent configuration for multi-task workflows
-> - ✅ Optional Git verification after each subtask completion
+> **What's New in v3.4.0**:
+> - 🧪 **TDD Workflow Streamlining**: Unified IMPL_PLAN.md structure, 33% reduction in redundant files
+> - 🔄 **Test Coverage Analysis**: TDD workflow upgraded to 6 phases with Phase 3 test context gathering
+> - 🔁 **Iterative Green Phase**: Built-in test-fix-cycle in IMPL tasks with Gemini auto-diagnosis
+> - 🛠️ **Manual-First Fixes**: Gemini + bug-fix template diagnosis by default, optional `--use-codex` automation
+> - ✅ **Test-Gen Workflow Enhancement**: Added 3 supporting tool commands for complete test generation flow
+> - ⏱️ **Dynamic Timeout Allocation**: CLI tools default to 20-120min for large-scale analysis
