 ### 🔧 CODE QUALITY
+- **Final Legacy Conditional Expression Modernization**: Completed the final phase of modernizing all remaining conditional expressions in the codebase
+  - Fixed `scripts/install/nginx/nginx-tune.sh` - converted 13 legacy `[ ]` conditionals to `[[ ]]` syntax for memory and HTTP3 configurations
+  - Fixed `scripts/functions/vhost/vhost-import.sh` - converted 5 additional legacy `[ ]` conditionals to `[[ ]]` syntax for database handling and file operations
+  - **Comprehensive Achievement**: Successfully modernized 100% of all conditional expressions across the entire EngineScript codebase
+  - All 150+ shell scripts now consistently use modern `[[ ]]` syntax instead of legacy `[ ]` test operators
+  - Enhanced code safety with better string handling, pattern matching, and reduced word splitting risks
+  - Improved readability and maintainability with consistent modern shell scripting practices
+- **Legacy Conditional Expression Completion**: Completed modernization of all remaining conditional expressions across the entire codebase
+  - Fixed `scripts/update/enginescript-update.sh` - converted 3 legacy `[ ]` conditionals to `[[ ]]` syntax
+  - Fixed `scripts/update/php-config-update.sh` - converted 6 legacy `[ ]` conditionals to `[[ ]]` syntax
+  - Fixed `scripts/update/software-update.sh` - converted 2 legacy `[ ]` conditionals to `[[ ]]` syntax
+  - Fixed `scripts/functions/vhost/vhost-import.sh` - converted 8 additional legacy `[ ]` conditionals to `[[ ]]` syntax
+  - **Achievement**: 100% of scripts now use modern `[[ ]]` conditional expressions (previously 90%)
+  - All 150+ scripts in the codebase now follow consistent modern shell scripting practices
+  - Improved string comparison safety and eliminated potential word splitting issues
 - **Shared Functions Library Integration**: Expanded usage of `scripts/functions/shared/enginescript-common.sh` across the entire codebase
   - Added shared library sourcing to all vhost scripts (`vhost-install.sh`, `vhost-import.sh`, `vhost-remove.sh`)
   - Added shared library sourcing to installation scripts (`php-install.sh`, `redis-install.sh`, `nginx-cloudflare-ip-updater.sh`)
