+TIP: Use `editor.documentBaseURI.getURI()` for all base URL operations.
 
 **Impact**: This change improves URL handling consistency by removing an undocumented API that was not aligned with the documented `documentBaseURI` property.
 
 **Migration steps:**
 
-To update all references of `documentBaseUrl` to the new API, replace any usage of `editor.documentBaseUrl` (or similar) with `tinymce.activeEditor.documentBaseURI.getURI()`. The property `documentBaseUrl` has been removed, and the correct way to access the document base URL is now through the `documentBaseURI` property, which is a URI object. You can then call `.getURI()` on it to get the string value of the URL.
