❌ Breaking Changes ❌

• Jaeger receiver no longer supports remote sampling. To be able to perform an update, it must be deactivated or replaced by a configuration of the jaegerremotesampling extension. It is important that the jaegerremotesampling extension and the jaegerreceiver do not use the same port. To increase the collector version afterwards, the update must be triggered again by restarting the operator. Alternatively, the OpenTelemetryCollector CRD can be re-created. (otel-contrib#14707)
