-## What's New in v1.2.1
+## What's New in v1.2.3 Release
+
+- Implemented a more advanced machine learning algorithm (LightGBM) for improved prediction accuracy.
+- Fine-tuned model parameters for enhanced performance and reliability.
+- Optimized data preprocessing steps to ensure consistent and effective training.
+- Updated data loading and preprocessing to handle text data more efficiently.
+- Streamlined the training pipeline for faster model training and deployment.
+- Enhanced model robustness with increased iterations and improved feature handling.
+- Integrated comprehensive error handling and logging for better debugging capabilities.
+- Improved overall code readability and maintainability.
 
-- **Initial Interaction Alert**: On the first interaction, the bot now displays an alert with guidance on how to format questions for better responses. This helps users understand the input format for optimal results.
-- **Unique Responses**: Updated the response mechanism to ensure that each response is unique and separated by a comma.
-- **Expanded Training Data**: The training data has been expanded to better handle a wider variety of questions, resulting in more accurate and relevant answers.
