- Removed configauth.Authentication (use configauth.Config) and extensionauthtest.NewErrorClient (use NewErr), introducing breaking changes.
- Added TPM support for TLS private key loading, pipeline component item count metrics, refined confmap merge behavior, and updated semconv import to go.opentelemetry.io/otel/semconv.
- Fixed exporterhelper batch config validation, reduced memory use when OTLP logs disabled, improved snappy content‑encoding handling, and added resource attributes to internal logs.
