Added

• Add Resource method to SDK in go.opentelemetry.io/contrib/otelconf/v0.3.0 to expose the resolved SDK resource from declarative configuration. (#8660)
• Add support to set the configuration file via OTEL_CONFIG_FILE in go.opentelemetry.io/contrib/otelconf. (#8639)
• Add support for service resource detector in go.opentelemetry.io/contrib/otelconf. (#8674)
• Add support for attribute_count_limit and attribute_value_length_limit in tracer provider configuration in go.opentelemetry.io/contrib/otelconf. (#8687)
• Add support for attribute_count_limit and attribute_value_length_limit in logger provider configuration in go.opentelemetry.io/contrib/otelconf. (#8686)
• Add support for server.address and server.port attributes in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#8723)
• Add support for OTEL_SEMCONV_STABILITY_OPT_IN in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. Supported values are rpc (default), rpc/dup and rpc/old. (#8726)
• Add the http.route metric attribute to go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. (#8632)

Changed

• Prepend _ to the normalized environment variable name when the key starts with a digit in go.opentelemetry.io/contrib/propagators/envcar, ensuring POSIX compliance. (#8678)
• Move experimental types from go.opentelemetry.io/contrib/otelconf to go.opentelemetry.io/contrib/otelconf/x. (#8529)
• Normalize cached environment variable names in go.opentelemetry.io/contrib/propagators/envcar, aligning Carrier.Keys output with the carrier's normalized key format. (#8761)

Fixed

• Fix go.opentelemetry.io/contrib/otelconf Prometheus reader converting OTel dot-style label names (e.g. service.name) to underscore-style (service_name) in target_info when both without_type_suffix and without_units are set. Use NoTranslation instead of UnderscoreEscapingWithoutSuffixes to preserve dot-style label names while still suppressing metric name suffixes. (#8763)
• Limit the request body size at 1MB in go.opentelemetry.io/contrib/zpages. (#8656)
• Fix server spans using the client's address and port for server.address and server.port attributes in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#8723)

Removed

• Host ID resource detector has been removed when configuring the host resource detector in go.opentelemetry.io/contrib/otelconf. (#8581)

Deprecated

• Deprecate OTEL_EXPERIMENTAL_CONFIG_FILE in favour of OTEL_CONFIG_FILE in go.opentelemetry.io/contrib/otelconf. (#8639)
