open-telemetry/opentelemetry-go v1.43.0 on GitHub

Added

Add IsRandom and WithRandom on TraceFlags, and IsRandom on SpanContext in go.opentelemetry.io/otel/trace
for W3C Trace Context Level 2 Random Trace ID Flag support. (#8012)
Add service detection with WithService in go.opentelemetry.io/otel/sdk/resource. (#7642)
Add DefaultWithContext and EnvironmentWithContext in go.opentelemetry.io/otel/sdk/resource to support plumbing context.Context through default and environment detectors. (#8051)
Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#8038)
Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc. (#8038)
Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc. (#8038)
Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp. (#8038)
Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp. (#8038)
Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#8038)
Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest. (#8038)
Add support for per-series start time tracking for cumulative metrics in go.opentelemetry.io/otel/sdk/metric.
Set OTEL_GO_X_PER_SERIES_START_TIMESTAMPS=true to enable. (#8060)
Add WithCardinalityLimitSelector for metric reader for configuring cardinality limits specific to the instrument kind. (#7855)

Changed

Introduce the EMPTY Type in go.opentelemetry.io/otel/attribute to reflect that an empty value is now a valid value, with INVALID remaining as a deprecated alias of EMPTY. (#8038)
Refactor slice handling in go.opentelemetry.io/otel/attribute to optimize short slice values with fixed-size fast paths. (#8039)
Improve performance of span metric recording in go.opentelemetry.io/otel/sdk/trace by returning early if self-observability is not enabled. (#8067)
Improve formatting of metric data diffs in go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest. (#8073)

Deprecated

Deprecate INVALID in go.opentelemetry.io/otel/attribute. Use EMPTY instead. (#8038)

Fixed

Return spec-compliant TraceIdRatioBased description. This is a breaking behavioral change, but it is necessary to
make the implementation spec-compliant. (#8027)
Fix a race condition in go.opentelemetry.io/otel/sdk/metric where the lastvalue aggregation could collect the value 0 even when no zero-value measurements were recorded. (#8056)
Limit HTTP response body to 4 MiB in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp to mitigate excessive memory usage caused by a misconfigured or malicious server.
Responses exceeding the limit are treated as non-retryable errors. (#8108)
Limit HTTP response body to 4 MiB in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp to mitigate excessive memory usage caused by a misconfigured or malicious server.
Responses exceeding the limit are treated as non-retryable errors. (#8108)
Limit HTTP response body to 4 MiB in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp to mitigate excessive memory usage caused by a misconfigured or malicious server.
Responses exceeding the limit are treated as non-retryable errors. (#8108)
WithHostID detector in go.opentelemetry.io/otel/sdk/resource to use full path for kenv command on BSD. (#8113)
Fix missing request.GetBody in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp to correctly handle HTTP2 GOAWAY frame. (#8096)
