Highlights

This release expands AppSec and serverless support. It adds AWS Lambda integration and ensures the client IP is always collected when AI Guard is enabled.

Tracing now includes inferred proxy spans for services behind AWS Gateway. It also adds support for DD_HOSTNAME, which controls trace hostnames and the OpenTelemetry host.name value when hostname reporting is enabled.

We’ve also enhanced crash reports to include all threads for better debugging context.
