+          Custom Python ${{ github.event.inputs.python_version }} binary build for Linux with glibc 2.36 compatibility
+          
+          **Build Configuration:**
+          - Python Version: ${{ github.event.inputs.python_version }}
+          - glibc Version: ${{ env.GLIBC_VERSION }}
+          - Optimization Level: 2 (full optimizations with LTO)
+          - With Pip/Setuptools/Wheel: Yes
+          - Architecture: ${{ env.ARCHITECTURE }}
+          - Build Date: ${{ env.BUILD_DATE }}
+          - Built by: anubhavkrishna1
+          - Container: Ubuntu 18.04 for maximum compatibility
+          
+          **Features:**
+          - Compatible with older Linux distributions (glibc 2.36+)
+          - Shared libraries enabled for better compatibility
+          - SSL/TLS support included
+          - SQLite extensions support
+          - Optimized with LTO and PGO
+          
+          **Installation:**
+          1. Download the tar.gz file
+          2. Download and run the install.sh script: `bash install.sh [install_path]`
+          3. Or extract manually: `tar -xzf ${{ env.PACKAGE_NAME }}.tar.gz -C /your/install/path`
