Umbraco releases v9
Validate runtime and extensions separately from model changes. Back up and test both workstreams independently to isolate failures.
Putting content management into practice
A content model defines independently maintained and reusable information. Authoring, preview, approval and publication form a workflow; an API response validates only one part.
Checking the result
Have real editors create, change and restore content using long headings, missing fields and multiple languages. Record development dependencies and release ownership.
