Description

The opentelemetry-jaeger crate is deprecated and no longer actively maintained. Its Jaeger propagator implementation has been migrated to a separate crate named opentelemetry-jaeger-propagator. Users are encouraged to refer to updated resources for native OpenTelemetry support in Jaeger and examples of exporting OTLP traces to Jaeger.

Impact

Defensive guidance

Users should migrate from the deprecated opentelemetry-jaeger crate to the actively maintained opentelemetry-jaeger-propagator crate. Refer to the official resources and examples for guidance on using OpenTelemetry with Jaeger. Continuing to use the deprecated crate is not recommended due to lack of maintenance and security updates.
