The changes involved refactor and clean-up of variable names. This encompasses making the names more descriptive and meaningful to enhance the readability of the code. Accuracy of variable names in conveying their usage and purpose has been greatly improved. The changes span across multiple files, touching crucial components like the server, rulesets, connection, and configuration handling.
