v0.72.0

The OpenTelemetry Collector Contrib contains everything in the opentelemetry-collector release (be sure to check the release notes here as well!).

v0.72.0

🛑 Breaking changes 🛑

• fluentbitextension: remove deprecated extension (#18505)

• all: Remove go 1.18 support, bump minimum to go 1.19 and add testing for 1.20 (#18436)

• pkg/ottl: switch ErrorMode to be a string instead of an int (#18692)

• hostmetricsreceiver: Remove deprecated process memory metrics (#14327)
  The metrics process.memory.physical_usage and process.memory.virtual_usage have been deprecated since v0.64.0.
  They are now being removed. You should use the following metrics instead: process.memory.usage, process.memory.virtual.
  For details, see the docs.

• promtailreceiver: Promtail recevier is completely removed from the repository (#18474, #18493)
  Promtail receiver in its current implementation has a dependency on Loki that leads to a huge amount of |
  dependencies. It is getting difficult to maintain those dependencies. That's why the decision to |
  remove promtail receiver was made

🚩 Deprecations 🚩

• jaegerexporter, jaegerthrifthttpexporter: marking jaeger exporters as deprecated (#18503)
• promtailreceiver: Deprecate promtail receiver (#18474, #18493)
  Promtail receiver in its current implementation has a dependency on Loki that leads to a huge amount of |
  dependencies. It is getting difficult to maintain those dependencies. That's why the decision to |
  deprecate and remove promtail receiver was made

• k8sobjectsreceiver: Improving watch mode reliability to handle recoverable issue such as API timeouts. (#18078)

• k8sattributeprocessor: Allow using k8s.pod.hostname to refer to pod.spec.hostname (#18494)

• translator/loki: Added default labels job=service.namespace/service.name and instance=service.instance.id to log record to send to Loki (#18500)

• pkg/ottl: Change typed getters to error on nil (#18735)

• pkg/ottl: Introduce the concept of type-specific Getters that help simplify type assertions in functions. (#18042)

• pkg/ottl: Add NewStatements func to enable creation of Statements structs. (#18385)

• redactionprocessor: Add IgnoreList to redaction processor (#18680)

• translator/prometheusremotewrite: Add metric name to error message when invalid (#18292)
  Exporter prometheusremotewrite doesn't support non-cumulative monotonic, histogram, and summary OTLP metrics.
  Added metric name to error message when the unsupported metrics get dropped.

• spanmetricsprocessor: Support set namespace for generated metric. (#18679)

• awsxrayreceiver: set service.name attribute (#18480)

• signalfxexporter: Add exclude_properties config option to filter dimension update property content (#18464)
