### Release Notes

<summary>open-telemetry/opentelemetry-go
(go.opentelemetry.io/otel/sdk)</summary>
###
[`v1.40.0`](https://redirect.github.com/open-telemetry/opentelemetry-go/releases/tag/v1.40.0):
/v0.62.0/v0.16.0
[Compare
Source](https://redirect.github.com/open-telemetry/opentelemetry-go/compare/v1.39.0...v1.40.0)
##### Overview
##### Added
- Add `Enabled` method to all synchronous instrument interfaces
(`Float64Counter`, `Float64UpDownCounter`, `Float64Histogram`,
`Float64Gauge`, `Int64Counter`, `Int64UpDownCounter`, `Int64Histogram`,
`Int64Gauge`,) in `go.opentelemetry.io/otel/metric`. This stabilizes the
synchronous instrument enabled feature, allowing users to check if an
instrument will process measurements before performing computationally
expensive operations.
([#​7763](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7763))
- Add `AlwaysRecord` sampler in `go.opentelemetry.io/otel/sdk/trace`.
([#​7724](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7724))
- Add `go.opentelemetry.io/otel/semconv/v1.39.0` package. The package
contains semantic conventions from the `v1.39.0` version of the
OpenTelemetry Semantic Conventions. See the [migration
documentation](https://redirect.github.com/open-telemetry/opentelemetry-go/blob/298cbedf256b7a9ab3c21e41fc5e3e6d6e4e94aa/semconv/v1.39.0/MIGRATION.md)
for information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.38.0.`
([#​7783](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7783),
[#​7789](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7789))
##### Changed
- `Exporter` in `go.opentelemetry.io/otel/exporters/prometheus` ignores
metrics with the scope `go.opentelemetry.io/contrib/bridges/prometheus`.
This prevents scrape failures when the Prometheus exporter is
misconfigured to get data from the Prometheus bridge.
([#​7688](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7688))
- Improve performance of concurrent histogram measurements in
`go.opentelemetry.io/otel/sdk/metric`.
([#​7474](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7474))
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/stdout/stdoutmetric`.
([#​7492](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7492))
- Improve the concurrent performance of `HistogramReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar` by 4x.
([#​7443](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7443))
- Improve performance of concurrent synchronous gauge measurements in
`go.opentelemetry.io/otel/sdk/metric`.
([#​7478](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7478))
- Improve performance of concurrent exponential histogram measurements
in `go.opentelemetry.io/otel/sdk/metric`.
([#​7702](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7702))
- Improve the concurrent performance of `FixedSizeReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar`.
([#​7447](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7447))
- The `rpc.grpc.status_code` attribute in the experimental metrics
emitted from
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` is
replaced with the `rpc.response.status_code` attribute to align with the
semantic conventions.
([#​7854](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7854))
- The `rpc.grpc.status_code` attribute in the experimental metrics
emitted from
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` is
replaced with the `rpc.response.status_code` attribute to align with the
semantic conventions.
([#​7854](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7854))
##### Fixed
- Fix bad log message when key-value pairs are dropped because of key
duplication in `go.opentelemetry.io/otel/sdk/log`.
([#​7662](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7662))
- Fix `DroppedAttributes` on `Record` in
`go.opentelemetry.io/otel/sdk/log` to not count the non-attribute
key-value pairs dropped because of key duplication.
([#​7662](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7662))
- Fix `SetAttributes` on `Record` in `go.opentelemetry.io/otel/sdk/log`
to not log that attributes are dropped when they are actually not
dropped.
([#​7662](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7662))
- `WithHostID` detector in `go.opentelemetry.io/otel/sdk/resource` to
use full path for `ioreg` command on Darwin (macOS).
([#​7818](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7818))
- Fix missing `request.GetBody` in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` to
correctly handle HTTP2 GOAWAY frame.
([#​7794](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7794))
##### Deprecated
- Deprecate `go.opentelemetry.io/otel/exporters/zipkin`. For more
information, see the [OTel blog post deprecating the Zipkin
exporter](https://opentelemetry.io/blog/2025/deprecating-zipkin-exporters/).

[Compare
Source](https://redirect.github.com/open-telemetry/opentelemetry-go/compare/v1.38.0...v1.39.0)
##### Overview
##### Added
- Greatly reduce the cost of recording metrics in
`go.opentelemetry.io/otel/sdk/metric` using hashing for map keys.
([#​7175](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7175))
- Add `WithInstrumentationAttributeSet` option to
`go.opentelemetry.io/otel/log`, `go.opentelemetry.io/otel/metric`, and
`go.opentelemetry.io/otel/trace` packages. This provides a
concurrent-safe and performant alternative to
`WithInstrumentationAttributes` by accepting a pre-constructed
`attribute.Set`.
([#​7287](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7287))
- Add experimental observability for the Prometheus exporter in
`go.opentelemetry.io/otel/exporters/prometheus`. Check the
`go.opentelemetry.io/otel/exporters/prometheus/internal/x` package
documentation for more information.
([#​7345](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7345))
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`.
([#​7353](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7353))
- Add temporality selector functions `DeltaTemporalitySelector`,
`CumulativeTemporalitySelector`, `LowMemoryTemporalitySelector` to
`go.opentelemetry.io/otel/sdk/metric`.
([#​7434](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7434))
- Add experimental observability metrics for simple log processor in
`go.opentelemetry.io/otel/sdk/log`.
([#​7548](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7548))
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
([#​7459](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7459))
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
([#​7486](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7486))
- Add experimental observability metrics for simple span processor in
`go.opentelemetry.io/otel/sdk/trace`.
([#​7374](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7374))
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`.
([#​7512](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7512))
- Add experimental observability metrics for manual reader in
`go.opentelemetry.io/otel/sdk/metric`.
([#​7524](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7524))
- Add experimental observability metrics for periodic reader in
`go.opentelemetry.io/otel/sdk/metric`.
([#​7571](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7571))
- Support `OTEL_EXPORTER_OTLP_LOGS_INSECURE` and
`OTEL_EXPORTER_OTLP_INSECURE` environmental variables in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`.
([#​7608](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7608))
- Add `Enabled` method to the `Processor` interface in
`go.opentelemetry.io/otel/sdk/log`. All `Processor` implementations now
include an `Enabled` method.
([#​7639](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7639))
- 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](./semconv/v1.38.0/MIGRATION.md) for information on how to
upgrade from
`go.opentelemetry.io/otel/semconv/v1.37.0.`([#​7648](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7175))
- `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/trace`
synchronously de-duplicates the passed attributes instead of delegating
it to the returned `TracerOption`.
([#​7266](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7266))
- `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/meter`
synchronously de-duplicates the passed attributes instead of delegating
it to the returned `MeterOption`.
([#​7266](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7266))
- `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/log`
synchronously de-duplicates the passed attributes instead of delegating
it to the returned `LoggerOption`.
([#​7266](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7266))
- Rename the `OTEL_GO_X_SELF_OBSERVABILITY` environment variable to
`OTEL_GO_X_OBSERVABILITY` in `go.opentelemetry.io/otel/sdk/trace`,
`go.opentelemetry.io/otel/sdk/log`, and
`go.opentelemetry.io/otel/exporters/stdout/stdouttrace`.
([#​7302](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7302))
- Improve performance of histogram `Record` in
`go.opentelemetry.io/otel/sdk/metric` when min and max are disabled
using `NoMinMax`.
([#​7306](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7306))
- 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](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7363))
- Replace fnv hash with xxhash in `go.opentelemetry.io/otel/attribute`
for better performance.
([#​7371](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7371))
- The default `TranslationStrategy` in
`go.opentelemetry.io/exporters/prometheus` is changed from
`otlptranslator.NoUTF8EscapingWithSuffixes` to
`otlptranslator.UnderscoreEscapingWithSuffixes`.
([#​7421](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7421))
- Improve performance of concurrent measurements in
`go.opentelemetry.io/otel/sdk/metric`.
([#​7427](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7427))
- Include W3C TraceFlags (bits 0–7) in the OTLP `Span.Flags` field in
`go.opentelemetry.io/exporters/otlp/otlptrace/otlptracehttp` and
`go.opentelemetry.io/exporters/otlp/otlptrace/otlptracegrpc`.
([#​7438](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7438))
- 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](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7357))
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`.
([#​7372](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7372))
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`.
([#​7372](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7372))
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`.
([#​7372](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7372))
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
([#​7372](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7372))
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
([#​7372](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7372))
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
([#​7372](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7372))
- Fix `AddAttributes`, `SetAttributes`, `SetBody` on `Record` in
`go.opentelemetry.io/otel/sdk/log` to not mutate input.
([#​7403](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7403))
- Do not double record measurements of `RecordSet` methods in
`go.opentelemetry.io/otel/semconv/v1.37.0`.
([#​7655](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7655))
- Do not double record measurements of `RecordSet` methods in
`go.opentelemetry.io/otel/semconv/v1.36.0`.
([#​7656](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7656))
##### Removed
- Drop support for \[Go 1.23].
([#​7274](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7274))
- Remove the `FilterProcessor` interface in
`go.opentelemetry.io/otel/sdk/log`. The `Enabled` method has been added
to the `Processor` interface instead. All `Processor` implementations
must now implement the `Enabled` method. Custom processors that do not
filter records can implement `Enabled` to return `true`.
([#​7639](https://redirect.github.com/open-telemetry/opentelemetry-go/issues/7639))
##### What's Changed
- Drop support for Go 1.23 by
