What's changed since 2.0

Most of the effort was put into maturing the zio-opentelemetry module.
In addition to Traces, the rest of the signals have been added:

• Metrics
• Logs
• Baggage

The correct synchronization between ZIO 2 runtime and java SDK auto-instrumentation agent was implemented.

The public APIs of all modules have been polished and documented.

What's next?

Now, when we support all types of OTEL signals, it is time to focus on adding smooth integration with the ZIO ecosystem of libraries.
To this end, new modules for zio-http, zio-grpc, zio-kafka, and so on are planned.

Seeing as more and more companies continue to migrate to OpenTelemetry, I believe that most of the development will be focused on the zio-opentelemetry module, and the zio-opencensus and zio-opentracing will gradually become obsolete.
