 ## Major vs. minor vs. patch releases
 
-A **major release** introduces significant changes, often including new features, architectural updates, or breaking changes; for example, moving from version 1.1.0 to 2.0.0. A **minor release** adds enhancements or new functionality that are backward-compatible, such as moving from version 1.1.0 to 1.2.0. Lastly, a **patch release** focuses on resolving critical bugs, security issues, or minor optimizations while maintaining backward compatibility, such as moving from version 1.1.1 to 1.1.2, and is intended to ensure stability and reliability without introducing new features.

This issue has now been fixed, allowing users to successfully turn off the built-in operator without conflict.  
+- **Performance Tuning for SQL-based Databases**: Running MySQL and PostgreSQL on Azure Container Storage is up to 5x faster on ephemeral disks. For more information and examples, refer to the [PostgreSQL on AKS deployment guide](/azure/aks/postgresql-ha-overview).
