- Deprecate flat keepalive fields in client and server configs in favor of the new keepalive section (deprecation, breaking).
- Breaking change: telemetry.Factory.CreateResource now returns (pcommon.Resource, string, error) to expose the resource schema URL, and the Factory interface is now experimental.
- Enhancements and bug fixes include Go 1.26 upgrade, Windows tier support, request‑size caching in exporterhelper, memory‑limiter health status updates, bounds checks in pprofile, and routing SDK internal errors through the collector logger.
