# 📚 RTD CHANGELOG SYNCHRONIZATION: Complete Version History Update

## Issue Identified
The Read the Docs (RTD) changelog was showing versions only up to **0.12.3**, while the main repository had released several major versions:
- ✅ v0.12.22 - Google Colab Compatibility & Clean Workflow  
- ✅ v0.12.23 - Critical RTD Documentation Parameter Fix
- ✅ v0.12.24 - Texture Analysis Warning Fix

## Root Cause Analysis
**Dual Changelog System**: edaflow maintains two changelog files:
1. `CHANGELOG.md` - Main repository changelog (✅ Up-to-date)
2. `docs/source/changelog.rst` - RTD-specific changelog (❌ Outdated)

**RTD Configuration**: Read the Docs builds from `docs/source/changelog.rst`, not the main `CHANGELOG.md` file, causing the documentation site to show outdated version information.

## Solution Implementation

### 📝 Updated RTD Changelog Structure
Added comprehensive entries for all missing versions:
