AWS aurora-dsql documentation change
Summary
Updated backup/restore documentation from preview limitations to general availability, clarified witness Region storage behavior, and removed preview disclaimers
Security assessment
Added explicit documentation about encrypted transaction logs in witness Regions and operational backup capabilities. While these are security-related features, there's no evidence this change addresses a specific active vulnerability or incident.
