Notable changes:

Breaking changes

• otelcol.receiver.otlp, otelcol.receiver.jaeger, otelcol.extension.jaeger_remote_sampling, otelcol.receiver.zipkin
  will now configure endpoint using localhost by default instead of 0.0.0.0.
  This may break the receiver in containerized environments like Kubernetes.
  If you depend on 0.0.0.0, configure the endpoint attribute to explicitly use 0.0.0.0.
• [otelcol.exporter.otlp,otelcol.exporter.loadbalancing]: Change the default gRPC load balancing strategy.
  The default value for the balancer_name attribute has changed to round_robin
  open-telemetry/opentelemetry-collector#10319

• Update Public preview remotecfg argument from metadata to attributes. (@erikbaranowski)

• The default value of the argument unmatched in the block routes of the component beyla.ebpf was changed from unset to heuristic (@marctc)

Features

• Added community components support, enabling community members to implement and maintain components. (@wildum)

• A new otelcol.exporter.debug component for printing OTel telemetry from
  other otelcol components to the console. (@BarunKGP)
