Clarify that calls to the Development SpanProcessor.OnEnding method are not
allowed after Shutdown.
(#5316)
Metrics
Specify that Shutdown of the periodic exporting MetricReader MUST include
the effects of ForceFlush.
(#5305)
Logs
Add systemd-journald example mapping to the logs data model appendix and align syslog mapping.
(#4995)
Resource
Update resource detectors to generate entities and indicate resource detectors should be entity-aware
unless new OTEL_EXPERIMENTAL_ENTITIES_ENABLED != true.
(#5147)
Remove OTEL_ENTITIES from general env var configuration spec.
(#5147)
Common
Stabilize Attribute and Attribute Collection representation for non-OTLP.
(#5149)
OpenTelemetry Protocol
Clarify that the OTLP exporter timeout bounds the entire batch export,
including all request attempts and waits between retries, and that earlier
caller deadlines take precedence.
(#5347)
Compatibility
Stabilize Prometheus Unknown-typed metric transformation.
(#5213)
Stabilize Prometheus Info metric transformation.
(#5211)
SDK Configuration
Declarative config should gracefully degrade when encountering unrecognized
resource detectors. Other SDK plugin components continue to produce errors
when missing.
(#5323)
Supplementary Guidelines
Allow narrowly scoped security-related changes to stable SDK and Contrib
behavior, configuration defaults, supported values, and emitted telemetry
without a major version bump, while preserving API compatibility and requiring
release notes describing the security rationale, user impact, and migration.
(#5357)
OTEPs
Add OTEP proposing a top-level span type field in API, SDK, and OTLP.
(#5233)
