Known Issues

This release contains a critical bug that may break applications using AWS SNS with immutable message attributes.

To avoid this bug you can either use v1.34.0 or turn off the SNS integration with this JVM option
-Ddd.integration.sns.enabled=false or this environment variable DD_INTEGRATION_SNS_ENABLED=false.

Turning off the SNS integration won't change the traces collected, but may cause some SNS traces to become disconnected.
