 ### Known Issues
 
+* Oracle databases are not supported in 11.9.0.
 * After you import a module with widgets (for example, the Data Widgets module) or just a widget, Studio Pro enters a state where subsequent imports of widget-containing modules silently fail. Studio Pro may appear to complete the import successfully but fails to actually import the module and its widgets. Studio Pro must be restarted to install another module with widgets, it is not sufficient to close the app or the Marketplace. The issue also persists for downloaded modules with widgets that are manually installed. <br/> We are working on the solution for this issue, the fix will be released as soon as possible in the upcoming patched versions.
