• Add support for per-series start time tracking for cumulative metrics in

<http://go.opentelemetry.io/otel/sdk/metric|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

<http://go.opentelemetry.io/otel/attribute|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)

• Improve slice handling in

<http://go.opentelemetry.io/otel/attribute|go.opentelemetry.io/otel/attribute>

to optimize short slice values with fixed-size fast paths. (#8039)

• Improve performance of span metric recording in

<http://go.opentelemetry.io/otel/sdk/trace|go.opentelemetry.io/otel/sdk/trace>

by returning early if self-observability is not enabled. (#8067)

• Improve formatting of metric data diffs in

<http://go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest|go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest>

. (#8073)

Deprecated

• Deprecate

INVALID

in

<http://go.opentelemetry.io/otel/attribute|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

<http://go.opentelemetry.io/otel/sdk/metric|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

<http://go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp|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

<http://go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp|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)

<http://go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp|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

<http://go.opentelemetry.io/otel/sdk/resource|go.opentelemetry.io/otel/sdk/resource>

to use full path for

kenv

command on BSD. (#8113)

• Fix missing

request.GetBody

in

<http://go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp|go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp>
