0.94.0

⛔ This release has a bug with the profiler where it produces profiles even if it's been configured to be disabled. A fix was released with version 0.94.1 and we encourage you to upgrade in case you have the profiler installed but disabled.

This release adds support to OpenTelemetry so that you can use the OpenTelemetry API to generate Datadog spans. This is off by default. Enable it with the environment variable DD_TRACE_OTEL_ENABLED=1 or INI setting datadog.trace.otel_enabled=1. Please, refer to the documentation to get started. Also, the tracer now generates 128 bits trace ids by default, in an effort to match OpenTelemetry standards.
