* [1]: The development of the metrics API and SDK has paused due to limited development resources, prioritization of a stable Traces release, and waiting for availability of stable Metrics (API + SDK) design from the OpenTelemetry specification. The current implementation can be included in build by setting `ENABLE_METRICS_PREVIEW` preprocessor macro.
* [1]: The development of the metrics API and SDK based on new stable specification is ongoing. The timelines would be available in release milestone. The earlier implementation (based on old specification) can be included in build by setting `ENABLE_METRICS_PREVIEW` preprocessor macro, and is included under `*/_metrics/*` directory. This would be eventually removed once the ongoing implemetation is stable.
* [2]: The current Log Signal Implementation is Experimental, and will change as the current OpenTelemetry Log specification matures. The current implementation can be included in build by setting `ENABLE_LOGS_PREVIEW` preprocessor macro.
