The go.opentelemetry.io/otel/semconv/v1.38.0 package.
The package contains semantic conventions from the v1.38.0 version of the OpenTelemetry Semantic Conventions.
See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.37.0.(#7648)
Changed
Distinct in go.opentelemetry.io/otel/attribute is no longer guaranteed to uniquely identify an attribute set.
Collisions between Distinct values for different Sets are possible with extremely high cardinality (billions of series per instrument), but are highly unlikely. (#7175)
WithInstrumentationAttributes in go.opentelemetry.io/otel/trace synchronously de-duplicates the passed attributes instead of delegating it to the returned TracerOption. (#7266)
WithInstrumentationAttributes in go.opentelemetry.io/otel/meter synchronously de-duplicates the passed attributes instead of delegating it to the returned MeterOption. (#7266)

Improve error handling for dropped data during translation by using prometheus.NewInvalidMetric in go.opentelemetry.io/otel/exporters/prometheus.
⚠️Breaking Change: Previously, these cases were only logged and scrapes succeeded.
Now, when translation would drop data (e.g., invalid label/value), the exporter emits a NewInvalidMetric, and Prometheus scrapes fail with HTTP 500 by default.
To preserve the prior behavior (scrapes succeed while errors are logged), configure your Prometheus HTTP handler with: promhttp.HandlerOpts{ ErrorHandling: promhttp.ContinueOnError }. (#7363)
Replace fnv hash with xxhash in go.opentelemetry.io/otel/attribute for better performance. (#7371)

The ErrorType function in go.opentelemetry.io/otel/semconv/v1.37.0 now handles custom error types.
If an error implements an ErrorType() string method, the return value of that method will be used as the error type. (#7442)
Fixed
Fix WithInstrumentationAttributes options in go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/metric, and go.opentelemetry.io/otel/log to properly merge attributes when passed multiple times instead of replacing them.
Attributes with duplicate keys will use the last value passed. (#7300)
The equality of attribute.Set when using the Equal method is not affected by the user overriding the empty set pointed to by attribute.EmptySet in go.opentelemetry.io/otel/attribute. (#7357)
Greatly reduce the cost of recording metrics in go.opentelemetry.io/otel/sdk/metric using hashing for map keys. (#7175)

</ul>
<h3>Changed</h3>
<ul>
<li><code>Distinct</code> in <code>go.opentelemetry.io/otel/attribute</code> is no longer guaranteed to uniquely identify an attribute set.
Collisions between <code>Distinct</code> values for different Sets are possible with extremely high cardinality (billions of series per instrument), but are highly unlikely. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7175">#7175</a>)</li>
<li><code>WithInstrumentationAttributes</code> in <code>go.opentelemetry.io/otel/trace</code> synchronously de-duplicates the passed attributes instead of delegating it to the returned <code>TracerOption</code>. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7266">#7266</a>)</li>
<li><code>WithInstrumentationAttributes</code> in <code>go.opentelemetry.io/otel/meter</code> synchronously de-duplicates the passed attributes instead of delegating it to the returned <code>MeterOption</code>. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7266">#7266</a>)</li>
<li><code>WithInstrumentationAttributes</code> in <code>go.opentelemetry.io/otel/log</code> synchronously de-duplicates the passed attributes instead of delegating it to the returned <code>LoggerOption</code>. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7266">#7266</a>)</li>
<li>Rename the <code>OTEL_GO_X_SELF_OBSERVABILITY</code> environment variable to <code>OTEL_GO_X_OBSERVABILITY</code> in <code>go.opentelemetry.io/otel/sdk/trace</code>, <code>go.opentelemetry.io/otel/sdk/log</code>, and <code>go.opentelemetry.io/otel/exporters/stdout/stdouttrace</code>. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7302">#7302</a>)</li>
<li>Improve performance of histogram <code>Record</code> in <code>go.opentelemetry.io/otel/sdk/metric</code> when min and max are disabled using <code>NoMinMax</code>. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7306">#7306</a>)</li>
<li>Improve error handling for dropped data during translation by using <code>prometheus.NewInvalidMetric</code> in <code>go.opentelemetry.io/otel/exporters/prometheus</code>.
⚠️ <strong>Breaking Change:</strong> Previously, these cases were only logged and scrapes succeeded.
Now, when translation would drop data (e.g., invalid label/value), the exporter emits a <code>NewInvalidMetric</code>, and Prometheus scrapes <strong>fail with HTTP 500</strong> by default.
To preserve the prior behavior (scrapes succeed while errors are logged), configure your Prometheus HTTP handler with: <code>promhttp.HandlerOpts{ ErrorHandling: promhttp.ContinueOnError }</code>. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7363">#7363</a>)</li>
<li>Replace fnv hash with xxhash in <code>go.opentelemetry.io/otel/attribute</code> for better performance. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7371">#7371</a>)</li>
<li>The default <code>TranslationStrategy</code> in <code>go.opentelemetry.io/exporters/prometheus</code> is changed from <code>otlptranslator.NoUTF8EscapingWithSuffixes</code> to <code>otlptranslator.UnderscoreEscapingWithSuffixes</code>. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7421">#7421</a>)</li>
<li>Improve performance of concurrent measurements in <code>go.opentelemetry.io/otel/sdk/metric</code>. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7427">#7427</a>)</li>
<li>Include W3C TraceFlags (bits 0–7) in the OTLP <code>Span.Flags</code> field in <code>go.opentelemetry.io/exporters/otlp/otlptrace/otlptracehttp</code> and <code>go.opentelemetry.io/exporters/otlp/otlptrace/otlptracegrpc</code>. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7438">#7438</a>)</li>
<li>The <code>ErrorType</code> function in <code>go.opentelemetry.io/otel/semconv/v1.37.0</code> now handles custom error types.
If an error implements an <code>ErrorType() string</code> method, the return value of that method will be used as the error type. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7442">#7442</a>)</li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Fix <code>WithInstrumentationAttributes</code> options in <code>go.opentelemetry.io/otel/trace</code>, <code>go.opentelemetry.io/otel/metric</code>, and <code>go.opentelemetry.io/otel/log</code> to properly merge attributes when passed multiple times instead of replacing them.
Attributes with duplicate keys will use the last value passed. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7300">#7300</a>)</li>
<li>The equality of <code>attribute.Set</code> when using the <code>Equal</code> method is not affected by the user overriding the empty set pointed to by <code>attribute.EmptySet</code> in <code>go.opentelemetry.io/otel/attribute</code>. (<a href="https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7357">#7357</a>)</li>
