-**ChemO Version 1.0 is now publicly available! 🎉**
+# ChemO Version 1.1
+
+Now with CDXML Files! 🎉
 
 The ChemO dataset has been officially released after meticulous proofreading and preparation. This benchmark is built from the **International Chemistry Olympiad (IChO) 2025** and represents a new frontier in automated chemical problem-solving.
 
 ## 🌟 Key Features
+
 - **🏆 Olympic-Level Benchmark** - Challenging problems from IChO 2025 for advanced AI reasoning
 - **🔬 Multimodal Symbolic Language** - Addresses chemistry's unique combination of text, formulas, and molecular structures
 - **📊 Two Novel Assessment Methods**:

 ## 📦 What's Included
+
 The current release includes:
+
 - ✅ **Original Problems** - Complete problem sets with additional chapter markers for Problems and Solutions sections (no other modifications to the original content)
 - ✅ **Well-structured JSON Files** - Clean, organized data designed for:
   - 🤖 **MLLM Benchmarking** - Olympic-level chemistry reasoning evaluation
   - 🔗 **Multi-Agent System Testing** - Hierarchical agent collaboration assessment
   - 🎯 **Multimodal Reasoning** - Text, formula, and molecular structure understanding
-- ⏳ **Original CDXML Files** - Coming soon (see note below)
+- ✅ **CDXML Files** - Molecular structure files now available in `JSON/cdxml/`
 
 ## 📋 Dataset Structure
-The ChemO dataset consists of **9 problems** from IChO 2025, with each problem provided as a structured JSON file (1.json ~ 9.json in `JSON/`). The `JSON/images/` directory contains all referenced images indexed in the JSON files.

 ## 📚 Data Source
-All problems are sourced from **ICHO 2025**: https://www.icho2025.ae/problems
 
-## 📝 Note on CDXML Files
-Due to compatibility issues across different ChemDraw versions, the CDXML files for molecular structures are not included in the initial v1.0 release. We are actively working to resolve these compatibility challenges and will supplement the dataset with CDXML files in a future update.
