This release enhances system performance by optimizing background job processing and event notifications. It also introduces more detailed event tracing for improved observability and strengthens data recovery operations to ensure business continuity.

### Improvements

*   Integrated comprehensive operator test suites into the main repository to ensure more rigorous, automated validation of core functionalities. (#419)
*   Added event duration and name to format event tracing, enabling faster analysis and troubleshooting of storage formatting operations via `mc admin trace`. (#421)

### Performance Optimizations

*   Optimized the cleanup frequency for completed batch jobs to reduce background system load and improve overall cluster responsiveness. (#425)
*   Adjusted default resource allocation for bucket event notifications to prevent system overload and ensure consistent delivery in large-scale deployments. (#423)

### Bug Fixes

*   Prevented potential cache errors during `xl.meta` backup reversions and added safeguards for undo operations on empty data directories, increasing the success rate of data recovery. (#422)
*   Resolved inconsistencies in hostname handling for notifications, simplifying configuration and ensuring uniform hostname presentation. (#418)
