+## 🚨 Important: Liquibase 5.0 Changes 🚨
+
+### Liquibase OSS vs Liquibase Secure
+
+Starting with **Liquibase 5.0**, we have introduced a clear separation between our open source Community edition and our commercial Secure offering:
+
+- **`liquibase/liquibase`** (OSS Edition): Community version under the Functional Source License (FSL)
+- **`liquibase/liquibase-secure`** (Secure Edition): Commercial version with enterprise features
+
+**If you have a valid Liquibase License Key, you should now use `liquibase/liquibase-secure` instead of `liquibase/liquibase`.**
+
+### 🚨 Breaking Change: Drivers and Extensions No Longer Included
+
+As of **Liquibase 5.0**, the OSS edition (`liquibase/liquibase`) and the official Docker OSS liquibase image **no longer include database drivers or extensions by default**.
+
+**What this means for you:**
+
+- You must now explicitly add database drivers using the Liquibase Package Manager (LPM)
+- Extensions must be manually installed or mounted into the container
+- MySQL driver installation via `INSTALL_MYSQL=true` environment variable is still supported

+
+### Adding Drivers with LPM
+
+```dockerfile
+FROM liquibase/liquibase:latest
+# Add database drivers as needed
+RUN lpm add mysql --global
+RUN lpm add postgresql --global
+RUN lpm add mssql --global
+```
