AWS documentdb documentation change
Summary
Entire documentation page for the $nin operator has been removed, including all content, examples, and code samples
Security assessment
The change removes documentation about the $nin query operator but does not mention any security vulnerability, weakness, or incident. This appears to be routine documentation cleanup or restructuring rather than addressing a security issue. No security implications are evident from the removal of this operator documentation.
