Summary

Added version-specific guidance (LZ v4.0 vs v3.3) regarding Security OU management and expanded list of exception controls

Security assessment

The changes clarify exception policies for security controls in different Control Tower versions and add new control IDs (CT.S3.PV.7, CT.S3.PV.8, CT.SNS.PV.1) to the exception list. While these controls relate to security configurations, there is no evidence this change addresses a specific vulnerability or incident - it appears to be documentation updates reflecting product changes and expanded exception options.
