[2.0.0] - 2025-09-28

🚀 Major Release - Architectural Evolution

This is a breaking change release with significant architectural improvements and new capabilities.

Added

🏗️ Four-Layer Architecture

• Interface Layer: CLI Commands with Gemini/Codex/Qwen Wrappers
• Session Layer: Atomic session management with .active-[session] markers
• Task/Data Layer: JSON-first model with .task/impl-*.json hierarchy
• Orchestration Layer: Multi-agent coordination and dependency resolution

🔄 Enhanced Workflow Lifecycle

• 6-Phase Development Process: Brainstorm → Plan → Verify → Execute → Test → Review
• Quality Gates: Validation at each phase transition
• Multi-perspective Planning: Role-based brainstorming with synthesis

🧪 Automated Test Generation

• Implementation Analysis: Scans completed IMPL-* tasks
• Multi-layered Testing: Unit, Integration, E2E, Performance, Security
• Specialized Agents: Dedicated test agents for different test types
• Dependency Mapping: Test execution follows implementation chains

✅ Plan Verification System

• Dual-Engine Validation: Gemini (strategic) + Codex (technical) analysis
• Cross-Validation: Conflict detection between vision and constraints
• Pre-execution Recommendations: Actionable improvement suggestions

🧠 Smart Tech Stack Detection

• Intelligent Loading: Only for development and code review tasks
• Multi-Language Support: TypeScript, React, Python, Java, Go, JavaScript
• Performance Optimized: Skips detection for non-relevant tasks
• Context-Aware Development: Applies appropriate tech stack principles

🔮 Qwen CLI Integration

• Architecture Analysis: System design patterns and code quality
• Code Generation: Implementation scaffolding and components
• Intelligent Modes: Auto template selection and precise planning
• Full Command Suite: analyze, chat, execute, mode:auto, mode:bug-index, mode:plan

🏷️ Issue Management Commands

• /workflow:issue:create - Create new project issues with priority/type
• /workflow:issue:list - List and filter issues by status/assignment
• /workflow:issue:update - Update existing issue status and assignments
• /workflow:issue:close - Close completed issues with resolution

📋 Enhanced Workflow Commands

• /workflow:plan-verify - Pre-execution validation using dual analysis
• /workflow:test-gen - Generate comprehensive test workflows
• /workflow:brainstorm:artifacts - Generate structured planning documents
• /workflow:plan-deep - Deep technical planning with Gemini analysis

🔧 Technical Improvements

• Enhanced Scripts: Improved gemini-wrapper and qwen-wrapper
• Cross-Platform: Windows path compatibility with proper quoting
• Directory Navigation: Intelligent context optimization
• Flow Control: Sequential execution with context accumulation
• Agent Enhancements: Smart context assessment and error handling

Changed

📚 Documentation Overhaul

• README.md: Updated to v2.0 with four-layer architecture
• README_CN.md: Chinese documentation aligned with v2.0 features
• Unified Structure: Consistent sections across language versions
• Command Standardization: Unified syntax and naming conventions

🔄 Command Syntax Updates

• Session Commands: /workflow:session list → /workflow:session:list
• File Naming: Standardized to lowercase .task/impl-*.json
• Session Markers: Unified format .active-[session]

🏗️ Architecture Improvements

• JSON-First Data Model: Single source of truth for all workflow state
• Atomic Session Management: Marker-based with zero-overhead switching
• Task Hierarchy: Standardized structure with intelligent decomposition

  • tech-stack-loader.sh
  • Legacy path reading scripts
• Obsolete Documentation: Python backend references in READMEs
• v1.3 Release Documentation: Removed erroneous v1.3.0 release files and tags

Fixed

🐛 Bug Fixes & Consistency

• Duplicate Content: Removed duplicate "Automated Test Generation" sections
• Script Entries: Fixed duplicate get_modules_by_depth.sh references
• File Path Inconsistencies: Standardized case sensitivity
• Command Syntax: Unified command naming across documentation
• Cross-Language Alignment: Synchronized English and Chinese versions

Security

[Unreleased] - 2025-09-07

🎯 Command Streamlining & Workflow Optimization

Command Name Updates

• RENAMED: /update_dms → /update-memory for consistency with kebab-case naming convention
• Updated: All documentation and references to reflect new command name

Command Structure Optimization

• REMOVED: Redundant context.md and sync.md commands (4 files total)
  • task/context.md - Functionality integrated into core task commands
  • task/sync.md - Replaced by automatic synchronization
  • workflow/context.md - Merged into workflow session management
  • workflow/sync.md - Built-in synchronization in workflow system
• CONSOLIDATED: context.md created as unified context management command
• Enhanced: Session status file management with automatic creation across all workflow commands

Documentation Cleanup

• REMOVED: 10 legacy documentation files including:
  • COMMAND_STRUCTURE_DESIGN.md
  • REFACTORING_COMPLETE.md
  • RELEASE_NOTES_v2.0.md
  • ROADMAP.md
  • TASK_EXECUTION_PLAN_SCHEMA.md
  • UNIFIED_TASK_MANAGEMENT.md
  • WORKFLOW_DOCUMENT_SYSTEM.md
