AWS powertools documentation change
Summary
Added changelog entries for version v3.28.0 (2026-04-14) including bug fixes, maintenance updates, documentation changes, and new features. Also updated table of contents and added new documentation sections for Lambda Features.
Security assessment
The changes are routine version updates and documentation improvements. No security vulnerabilities, weaknesses, or incidents are mentioned. The bug fixes (e.g., merging querystring parameters, authorizer response support, middleware fixes) appear to be functional improvements rather than security patches. Dependency updates include cryptography library bump (46.0.5 to 46.0.6), but without explicit security context in the changelog, this is considered routine maintenance.
