Release 1.47.0

1.47.0 (2023-07-05)

Backend Changes

⛔ Breaking Changes

• [SPM] Due to a breaking change in OpenTelemetry's prometheus exporter (details)
  metric names will no longer be normalized by default, meaning that the expected metric names would be calls and
  duration_[buckets|count|sum]. Backwards compatibility with older OpenTelemetry Collector versions can be achieved through the following flags:
  • prometheus.query.normalize-calls: If true, normalizes the "calls" metric name. e.g. "calls_total".
  • prometheus.query.normalize-duration: If true, normalizes the "duration" metric name to include the duration units. e.g. "duration_milliseconds_bucket".

New Features

• [Cassandra] Add Configuration.Close() to ensure TLS cert watcher is closed (@kennyaz in #4515)
• Add *.kerberos.disable-fast-negotiation option to Kafka consumer (@pmuls99 in #4520)
• Support Prometheus normalization for specific metrics related to OpenTelemetry compatibility (@albertteoh in #4555)

Release v1.46.0

Backend Changes

⛔ Breaking Changes

OTLP receiver is now enabled by default (#4494). This change follows the Jaeger's strategic direction of aligning closely with the OpenTelemetry project. This may cause port conflicts if jaeger-collector is depoyed in host network namespace. The original --collector.otlp.enabled option is still available and MUST be set to false if OTLP receiver is not desired.

New Features

• Make OTLP receiver enabled by default (@yurishkuro in #4494)
• [SPM] Add support for OpenTelemetry SpanMetrics Connector (@albertteoh in #4452). See Migration README.
