This release enhances cluster management and operational visibility, introducing customizable node health checks for faster failover and new metrics for monitoring data replication. Key improvements focus on accelerating data migration and improving performance under heavy load, alongside critical bug fixes that restore API functionality and increase the success rate of large-scale data operations.

### New Features
- Administrators can now customize the health check interval to accelerate the detection of unresponsive nodes and reduce failover time. (#851)
- Accelerate storage pool decommissioning with an option to skip source pool data cleanup, enabling faster data migration. (#871)
- Gain deeper visibility into data replication with new metrics for 'in progress' tasks and detailed target node information. (#845)
- Enable proactive license expiration warnings from the SUBNET service by including the license ID in cluster registration data. (#875)

### Improvements
- Improve performance during heavy data deletion by using rotating prefixes for trashed items, preventing single-directory bottlenecks. (#877)
- Extend event notification compatibility to include Elasticsearch server versions 7, 8, and 9 for broader integration options. (#820)
- Enhance drive failure detection by independently monitoring read and write operations, ensuring partially failing drives are correctly identified. (#848)
- Improve object lifecycle management (ILM) resilience by preventing errors when expiring objects that have already been deleted. (#855)
- Strengthen LDAP integration with improved configuration validation to prevent deployment issues from misconfigurations. (#776)
- Increase the success rate of site replication for large datasets by extending the operation timeout period. (#874)
- Reduce audit log noise by excluding internal system operations during tiered object decommissioning, focusing logs on user-initiated actions. (#880)

### Performance Improvements
- Optimize IAM key verification to improve server responsiveness and reduce processing delays in large-scale environments. (#863)
- Enhance multipart upload performance by enabling the multipart upload cache (`mpCache`) by default for standard deployments. (#866)
- Accelerate the deletion of empty buckets in large clusters through more efficient pre-check logic. (#878)

### Bug Fixes
- Resolved an issue causing '503 Service Unavailable' errors during large multipart uploads in high-latency stretched clusters. (#861)
- Fixed an incompatibility that prevented reading encrypted object metadata, ensuring reliable access to all encrypted objects. (#882, #885)
- Corrected a failure that could occur when deleting non-versioned S3 objects if a storage node was offline. (#854)
- Ensured that storage quota configurations on buckets created with older software versions are correctly enforced after an upgrade. (#870)
- Restored the `/minio/admin/v4/object-summary` administrative API endpoint to re-enable object summary retrieval. (#859)
- Restored two administrative API endpoints (`/idp/openid/list-access-keys-bulk` and `/info-access-key`) for managing OIDC access keys. (#857)
- Corrected an issue that could cause the MinIO Client (mc) to crash when displaying diagnostic data in a table format. (#864)
