📝 WalkthroughWalkthroughThis release introduces v2.8.41 with a comprehensive refactoring of test infrastructure via a new shared TestHelper module, extensive mysqltuner.pl improvements including replica terminology standardization and division-by-zero guards, updated GitHub Actions workflows with dynamic versioning, and formalized release governance rules. The 40+ test files are refactored to use the TestHelper pattern while mysqltuner.pl gains stronger CLI handling, improved credential logic, MySQL 9.x batch-mode compatibility, workload-aware InnoDB tuning, and more robust variable detection.
