+All notable changes to this project will be documented in this file.
 
-### 🚀 Core Features
+## [5.2.3] - 2025-12-15
 
-#### Skills System Enhancements
-- **New Skills**: Added `codeagent`, `product-requirements`, `prototype-prompt-generator` to `skill-rules.json`
-- **Auto-Activation**: Skills automatically trigger based on keyword/pattern matching via hooks
-- **Backward Compatibility**: Retained `skills/codex/SKILL.md` for existing workflows
+### 🐛 Bug Fixes
 
-#### Multi-Backend Support (codeagent-wrapper)
-- **Renamed**: `codex-wrapper` → `codeagent-wrapper` with pluggable backend architecture
-- **Three Backends**: Codex (default), Claude, Gemini via `--backend` flag
-- **Smart Parser**: Auto-detects backend JSON stream formats
-- **Session Resume**: All backends support `-r <session_id>` cross-session resume
-- **Parallel Execution**: DAG task scheduling with global and per-task backend configuration
-- **Concurrency Control**: `CODEAGENT_MAX_PARALLEL_WORKERS` env var limits concurrent tasks (max 100)
-- **Test Coverage**: 93.4% (backend.go 100%, config.go 97.8%, executor.go 96.4%)
