We're pleased to announce SOAR v2.4.16, a focused maintenance release that enhances system reliability and stability across the platform.

Key Improvements

Error Handling Consistency

• Fixed AWS Step Functions retry logic to properly catch Lambda throttling exceptions
• Corrected TooManyRequestsException to Lambda.TooManyRequestsException in state machine configurations
• Improved resilience during high-concurrency operations

Recent Stability Enhancements (v2.4.11-v2.4.15)

• Enhanced robustness in local suppression checking functions
• Pinned Python library versions across all SOAR functions for consistent builds
• Fixed account reassignment processor permissions using generic ProductArn defaults
• Improved Lambda enrichment to use actual ARNs from alarm generators
• Enhanced DynamoDB permissions for CloudWatch context enrichment with GSI access
• Removed unreliable heuristics fallback logic and added complete event logging

Benefits

• Improved Reliability: Better handling of AWS service throttling and high-load scenarios
• Enhanced Stability: Consistent library versions prevent build-time dependency conflicts
• Operational Resilience: More robust error handling across critical SOAR workflows

Upgrade Information

Direct upgrade available from any v2.x version with no additional configuration required. This maintenance release focuses on behind-the-scenes improvements that
