# Proposal: Integrate v1.6.1.x Release Information into Main CHANGELOG

**Change ID**: `integrate-v1-6-1-x-releases`  
**Status**: Completed  
**Created**: 2025-11-04  
**Author**: Roo Code AI Assistant

## 1. Overview

### 1.1 Purpose
Integrate release information from parallel development branches (v1.6.1.1 through v1.6.1.4) into the main CHANGELOG.md file on the develop branch. These releases were developed in separate release branches and contain important features that need to be documented in the main project history.

### 1.2 Background
During October 2025, four releases (v1.6.1.1, v1.6.1.2, v1.6.1.3, and v1.6.1.4) were developed on separate release branches:
- `release/v1.6.1.1` - Logging control enhancements
- `release/v1.6.1.2` - Version synchronization
- `release/v1.6.1.3` - LLM guidance and multilingual support
- `release/v1.6.1.4` - Streaming file reading performance optimization

These changes were not present in the main develop branch's CHANGELOG.md and needed to be integrated.

## 2. User Value

### 2.1 Documentation Completeness
- **Complete Version History**: All releases are now documented in chronological order
- **Transparency**: Users can understand the full evolution of the project
- **Feature Discovery**: Users can discover features added in v1.6.1.x releases

### 2.2 Change Management Compliance
- **PMP Alignment**: Follows the project's change management policy (PM-005)
- **Historical Accuracy**: Maintains accurate project history for auditing and compliance
- **OpenSpec Best Practices**: Uses OpenSpec methodology for documentation changes

## 3. Impact Analysis

### 3.1 Affected Components
- **Primary**: `CHANGELOG.md` - Main changelog file
- **Secondary**: None (documentation-only change)

### 3.2 Scope
- **In-Scope**:
  - Integration of v1.6.1.1, v1.6.1.2, v1.6.1.3, and v1.6.1.4 entries
  - Proper chronological placement between v1.6.2 and v1.6.0
  - Preservation of all original content and formatting
  - OpenSpec documentation of the change process

- **Out-of-Scope**:
  - Code changes (no source code modifications)
  - Test changes (no test additions or modifications)
  - Feature implementation (purely documentation)

### 3.3 Risk Assessment
- **Risk Level**: Low
- **Rationale**: Documentation-only change with no code impact
- **Mitigation**: Careful review of chronological ordering and content accuracy

## 4. Technical Approach

### 4.1 Information Gathering
1. Identified release branches: `origin/release/v1.6.1.1` through `origin/release/v1.6.1.4`
2. Extracted CHANGELOG.md content from each branch using `git show`
3. Verified content accuracy and completeness

### 4.2 Integration Strategy
1. Located insertion point: Between v1.6.2 and v1.6.0 in main CHANGELOG.md
2. Inserted entries in reverse chronological order: v1.6.1.4 → v1.6.1.3 → v1.6.1.2 → v1.6.1.1
3. Maintained original formatting, emojis, and structure
4. Added separator lines (---) between major version entries

### 4.3 Quality Assurance
- ✅ Chronological order verified
- ✅ No duplicate entries
- ✅ Formatting consistency maintained
- ✅ All features documented with technical details
