DDTrace Extension Changelog

Introduction¶

This document records updates to the Java extension package used in DataKit for DDTrace Java instrumentation compatibility scenarios. This extension is developed based on DataDog/dd-trace-java and follows the Apache License 2.0. For legal files, checksums, and source code change details, see the Guance Java Tracer Extension Notice.

Use this changelog to identify the version where an extension capability first appeared, changed behavior, or was fixed. It is not a complete configuration manual. For a safe rollout:

1. Pin the exact extended-JAR version in the deployment manifest.
2. Use this log to confirm the target capability's minimum version and later behavior changes.
3. Return to the Java extension guide for configuration, data-safety boundaries, and verification.
4. Complete compatibility tests in pre-production before a production upgrade.

Historical entries preserve their release-time meaning. A newer version does not necessarily retain every early experimental behavior.
