AWS powertools documentation change
Summary
Added changelog entry for version v3.26.0 with new features, bug fixes, maintenance updates, and dependency bumps
Security assessment
The changes are routine version updates and feature additions. While there are dependency updates (including urllib3 and cryptography), the changelog doesn't mention any security vulnerabilities being fixed. The addition of fuzzing tests (#7903) is a security practice but doesn't document a specific security issue. No concrete evidence of addressing a security vulnerability is present in the diff.
