AWS opensearch-service documentation change

Service: opensearch-service · 2025-04-11 · Documentation low

File: opensearch-service/latest/developerguide/knn.md

Summary

Removed detailed version compatibility tables between OpenSearch Service and k-NN plugin versions, simplified introductory text to focus on general overview rather than specific version features

Security assessment

The changes remove technical details about plugin version compatibility and feature history without any mention of security vulnerabilities, patches, or security-related features. This appears to be a documentation simplification rather than addressing security concerns.
