1.35.0

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 upgrade to v1.35.2, revert to 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.

Potentially Breaking Changes

Warning

Enable by default the Spring Boot environment instrumentation that infers the service name to the value of spring.application.name if the user did not provide any DD_SERVICE configuration.
Check #7029 for more details and how to revert it.
