This release introduces powerful new observability with OpenTelemetry distributed tracing, simplifying performance analysis and diagnostics. Key enhancements include support for appending data to objects for more efficient workflows and detailed replication statistics for improved operational insight. These updates provide administrators with greater control and visibility over their critical data infrastructure.

### New Features

*   **Introduces OpenTelemetry distributed tracing** for end-to-end visibility into S3 requests and internal operations, simplifying performance analysis and troubleshooting. (#552)
*   **Adds support for appending data to existing objects** in S3 Express One Zone, streamlining workflows for growing files like logs by eliminating full re-uploads. (#572)

### Improvements

*   **Enhances replication status reporting** with detailed statistics for retries, errors, and link downtime, providing deeper insight for diagnosing replication health. (#474)
*   **Upgrades the embedded AIStor console** to allow direct management of access keys and corrects the display of encrypted bucket information. (#604)

### Bug Fixes

*   **Resolves an issue preventing `List()` operations from using caching**, resulting in significantly faster response times for frequent listings. (#595)
*   **Fixes inaccurate reporting of batch job metrics** during server startup and improves the robustness of the batch job initialization process. (#545)
*   **Ensures background data healing processes terminate correctly** upon completion or cancellation, preventing resource leaks and improving system efficiency. (#602)

### Security Updates

*   **Corrects a flaw in the token revocation process** that could allow revoked tokens to become active again, ensuring access policies are consistently enforced. (#596)
