open-telemetry/opentelemetry-collector v0.140.0 on GitHub

End User Changelog

cmd/mdatagen: metadata.yaml now supports an optional entities section to organize resource attributes into logical entities with identity and description attributes (#14051)
When entities are defined, mdatagen generates AssociateWith{EntityType}() methods on ResourceBuilder
that associate resources with entity types using the entity refs API. The entities section is backward
compatible - existing metadata.yaml files without entities continue to work as before.
cmd/mdatagen: Add semconv reference for metrics (#13920)
connector/forward: Add support for Profiles to Profiles (#14092)
exporter/debug: Disable sending queue by default (#14138)
The recently added sending queue configuration in Debug exporter was enabled by default and had a problematic default size of 1.
This change disables the sending queue by default.
Users can enable and configure the sending queue if needed.
pkg/config/configoptional: Mark configoptional.AddEnabledField as beta (#14021)

See https://github.com/open-telemetry/opentelemetry-proto/releases/tag/v1.9.0
pkg/otelcol: The otelcol.Factories.Telemetry field is now required (#14003)
Previously if this field was not set, then it would default to an otelconftelemetry factory.
Callers of the otelcol package must now set the field explicitly.
