 ## Minor vs. patch versions
 
-Minor versions introduce small improvements, performance enhancements, or minor new features without breaking existing functionality. For example, version 1.1.0 would move to 1.2.0.

+
+### Improvements and issues that are fixed 
+- **Bug fixes and performance improvements**: General stability improvements have been made to address key recovery issues, especially during upgrade scenarios. These updates are designed to ensure more reliable recovery processes and prevent unexpected service interruptions, delivering a smoother and more consistent experience.  
+- **Ephemeral Disk Performance Enhancements**: We improved overall performance for Azure Container Storage with ephemeral NVMe disks as the backing storage option, delivering up to a 100% increase in write IOPS in setups with replication enabled. For more details, read about ephemeral disk performance [using local NVMe](/azure/storage/container-storage/use-container-storage-with-local-disk#optimize-performance-when-using-local-nvme) and [using local NVMe with replication](/azure/storage/container-storage/use-container-storage-with-local-nvme-replication#optimize-performance-when-using-local-nvme).
