AWS documentdb documentation change
Summary
Restructured release notes from grouping by engine version to a chronological list by release date, updated with new entries up to February 2026, and reorganized content for better readability.
Security assessment
The changes involve reorganizing existing content and adding new release dates, but there is no concrete evidence in the diff of addressing specific security vulnerabilities, weaknesses, or incidents. Security-related features like TLS version support and client-side encryption are mentioned, but these are part of routine feature updates rather than fixes for security issues.
