### Changed
- ⚠️ **Breaking Change:** `go.opentelemetry.io/otel/sdk/metric` now
applies a default cardinality limit of 2000 to comply with the Metrics
SDK specification recommendation.
New attribute sets are dropped when the cardinality limit is reached.
The measurement of these sets are aggregated into a special attribute
set containing `attribute.Bool("otel.metric.overflow", true)`.
This can break users who relied on the previous unlimited default.
Set `WithCardinalityLimit(0)` or the deprecated
`OTEL_GO_X_CARDINALITY_LIMIT=0` environment variable to preserve
unlimited cardinality.
Note that support for `OTEL_GO_X_CARDINALITY_LIMIT` may be removed in a
future release. (#8247)
- `ErrorType` in `go.opentelemetry.io/otel/semconv` now unwraps errors
created with `fmt.Errorf` when deriving the `error.type` attribute.
(#8133)
- `go.opentelemetry.io/otel/sdk/log` now unwraps error chains created
with `fmt.Errorf` when deriving the `error.type` attribute from errors
on log records. (#8133)
- `Set.MarshalLog` method in `go.opentelemetry.io/otel/attribute` now
uses `Value.String` formatting following the [OpenTelemetry AnyValue
representation for non-OTLP
protocols](https://opentelemetry.io/docs/specs/otel/common/#anyvalue).
(#8169)
- Optimize `go.opentelemetry.io/otel/sdk/metric` to return a drop
reservoir and short-circuit `Offer` calls to the exemplar reservoir when
`exemplar.AlwaysOffFilter` is configured. (#8211) (#8267)
- Optimize `go.opentelemetry.io/otel/sdk/metric` to return a drop
reservoir for asynchronous instruments when `exemplar.TraceBasedFilter`
is configured. (#8286)
### Deprecated
- Deprecate `Value.Emit` method in `go.opentelemetry.io/otel/attribute`.
Use `Value.String` instead. (#8176)
### Fixed
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in

The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Limit OTLP request size to 64 MiB by default in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`.
The limit applies before compression, oversized requests are treated as
non-retryable errors, and the limit can be configured with the new
`WithMaxRequestSize` option. (#8157, #8365)
- Fix gzipped request body replay on redirect in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#8135)
- Fix gzipped request body replay on redirect in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8152)
- `go.opentelemetry.io/otel/exporters/prometheus` now uses
`Value.String` formatting for label values following the [OpenTelemetry
AnyValue representation for non-OTLP
protocols](https://opentelemetry.io/docs/specs/otel/common/#anyvalue).
(#8170)
- Propagate errors from the exporter when calling `Shutdown` on
`BatchSpanProcessor` in `go.opentelemetry.io/otel/sdk/trace`. (#8197)

`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` and
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8226)
- Fix a concurrent `Collect` data race and potential panic in
`go.opentelemetry.io/otel/exporters/prometheus` when
`WithResourceAsConstantLabels` option is used. (#8227)
- Fix race condition in `FixedSizeReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar` by reverting #7447.
(#8249)
- Fix `FixedSizeReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar` to safely handle zero
size.
A capacity check in the constructor initializes the reservoir safely and
skips initialization for zero-cap; early returns in `Offer()` and
`Collect()` ensure no-op behavior. (#8295)
- Fix counting of spans and logs in self-observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`,
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`,
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`, and
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8254)
- Drop conflicting scope attributes named `name`, `version`, or
`schema_url` from metric labels in
`go.opentelemetry.io/otel/exporters/prometheus`, preserving the
dedicated `otel_scope_name`, `otel_scope_version`, and
`otel_scope_schema_url` labels. (#8264)
- Close schema files opened by `ParseFile` in
`go.opentelemetry.io/otel/schema/v1.0` and
`go.opentelemetry.io/otel/schema/v1.1`.
([GHSA-995v-fvrw-c78m](https://github.com/open-telemetry/opentelemetry-go/security/advisories/GHSA-995v-fvrw-c78m))
- Enforce the 8192-byte baggage size limit during extraction/parsing,
changing behavior when the limit is exceeded in
`go.opentelemetry.io/otel/baggage` and
`go.opentelemetry.io/otel/propagation`. (#8222)
- Fix `go.opentelemetry.io/otel/semconv/v1.41.0` to include `Attr*`
helper methods for required attributes on observable instruments.
(#8361)
- Limit baggage extraction error reporting in
`go.opentelemetry.io/otel/propagation` to prevent malformed or oversized
baggage headers from flooding logs.

### Added
- Add `go.opentelemetry.io/otel/semconv/v1.40.0` package.
The package contains semantic conventions from the `v1.40.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.40.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.39.0`. (#7985)
- Add `Err` and `SetErr` on `Record` in `go.opentelemetry.io/otel/log`
to attach an error and set record exception attributes in
`go.opentelemetry.io/otel/log/sdk`. (#7924)
### Changed
- `TracerProvider.ForceFlush` in `go.opentelemetry.io/otel/sdk/trace`
joins errors together and continues iteration through SpanProcessors as
opposed to returning the first encountered error without attempting
exports on subsequent SpanProcessors. (#7856)
### Fixed
- Fix missing `request.GetBody` in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` to
correctly handle HTTP2 GOAWAY frame. (#7931)
- Fix semconv v1.39.0 generated metric helpers skipping required
attributes when extra attributes were empty. (#7964)
- Preserve W3C TraceFlags bitmask (including the random Trace ID flag)
during trace context extraction and injection in
`go.opentelemetry.io/otel/propagation`. (#7834)
### Removed
- Drop support for [Go 1.24]. (#7984)
This release is the last to support [Go 1.24].
The next release will require at least [Go 1.25].
### Added
- Support testing of [Go 1.26]. (#7902)
### Fixed
- Update `Baggage` in `go.opentelemetry.io/otel/propagation` and `Parse`
and `New` in `go.opentelemetry.io/otel/baggage` to comply with W3C
Baggage specification limits.
`New` and `Parse` now return partial baggage along with an error when
limits are exceeded.
Errors from baggage extraction are reported to the global error handler.
(#7880)
[Go 1.26]: https://go.dev/doc/go1.26
[Go 1.25]: https://go.dev/doc/go1.25
[Go 1.24]: https://go.dev/doc/go1.24
### 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)
- Add `AlwaysRecord` sampler in `go.opentelemetry.io/otel/sdk/trace`.
(#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://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, #7789)
### Changed
- `Exporter` in `go.opentelemetry.io/otel/exporter/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)
- Improve performance of concurrent histogram measurements in
`go.opentelemetry.io/otel/sdk/metric`. (#7474)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/stdout/stdoutmetric`. (#7492)

- Improve performance of concurrent exponential histogram measurements
in `go.opentelemetry.io/otel/sdk/metric`. (#7702)
- Improve the concurrent performance of `FixedSizeReservoir` in
`go.opentelemetry.io/otel/sdk/metric/exemplar`. (#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)
- 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)
### Fixed
- Fix bad log message when key-value pairs are dropped because of key
duplication in `go.opentelemetry.io/otel/sdk/log`. (#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)
- 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)
- `WithHostID` detector in `go.opentelemetry.io/otel/sdk/resource` to
use full path for `ioreg` command on Darwin (macOS). (#7818)
- Fix missing `request.GetBody` in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` to
correctly handle HTTP2 GOAWAY frame. (#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/).

## Overview
### Added
- Greatly reduce the cost of recording metrics in
`go.opentelemetry.io/otel/sdk/metric` using hashing for map keys.
(#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)
- 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)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#7353)
- Add temporality selector functions `DeltaTemporalitySelector`,
`CumulativeTemporalitySelector`, `LowMemoryTemporalitySelector` to
`go.opentelemetry.io/otel/sdk/metric`. (#7434)
- Add experimental observability metrics for simple log processor in
`go.opentelemetry.io/otel/sdk/log`. (#7548)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
(#7459)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#7486)
- Add experimental observability metrics for simple span processor in
`go.opentelemetry.io/otel/sdk/trace`. (#7374)
- Add experimental observability metrics in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7512)
- Add experimental observability metrics for manual reader in
`go.opentelemetry.io/otel/sdk/metric`. (#7524)
- Add experimental observability metrics for periodic reader in
`go.opentelemetry.io/otel/sdk/metric`. (#7571)
- Support `OTEL_EXPORTER_OTLP_LOGS_INSECURE` and
`OTEL_EXPORTER_OTLP_INSECURE` environmental variables in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7608)
- Add `Enabled` method to the `Processor` interface in
`go.opentelemetry.io/otel/sdk/log`. All `Processor` implementations now
include an `Enabled` method. (#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)
### 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)
- `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/log`
synchronously de-duplicates the passed attributes instead of delegating
it to the returned `LoggerOption`. (#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)
- Improve performance of histogram `Record` in
`go.opentelemetry.io/otel/sdk/metric` when min and max are disabled
using `NoMinMax`. (#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)
- Replace fnv hash with xxhash in `go.opentelemetry.io/otel/attribute`
for better performance. (#7371)
- The default `TranslationStrategy` in
`go.opentelemetry.io/exporters/prometheus` is changed from
`otlptranslator.NoUTF8EscapingWithSuffixes` to
`otlptranslator.UnderscoreEscapingWithSuffixes`. (#7421)
- Improve performance of concurrent measurements in
`go.opentelemetry.io/otel/sdk/metric`. (#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)
- 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)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`.
(#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`.
(#7372)
- Return partial OTLP export errors to the caller in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#7372)
- Fix `AddAttributes`, `SetAttributes`, `SetBody` on `Record` in
`go.opentelemetry.io/otel/sdk/log` to not mutate input. (#7403)
- Do not double record measurements of `RecordSet` methods in
`go.opentelemetry.io/otel/semconv/v1.37.0`. (#7655)
- Do not double record measurements of `RecordSet` methods in
`go.opentelemetry.io/otel/semconv/v1.36.0`. (#7656)
### Removed
- Drop support for [Go 1.23]. (#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)
This release is the last to support [Go 1.23].
The next release will require at least [Go 1.24].
### Added
- Add native histogram exemplar support in
`go.opentelemetry.io/otel/exporters/prometheus`. (#6772)

which can be used to disable deduplication for log records. (#6968)
- Add `WithCardinalityLimit` option to configure the cardinality limit
in `go.opentelemetry.io/otel/sdk/metric`. (#6996, #7065, #7081, #7164,
#7165, #7179)
- Add `Clone` method to `Record` in `go.opentelemetry.io/otel/log` that

- Add experimental self-observability span and batch span processor
metrics in `go.opentelemetry.io/otel/sdk/trace`. Check the
`go.opentelemetry.io/otel/sdk/trace/internal/x` package documentation
for more information. (#7027, #6393, #7209)
- The `go.opentelemetry.io/otel/semconv/v1.36.0` package. The package
contains semantic conventions from the `v1.36.0` version of the
OpenTelemetry Semantic Conventions. See the [migration
documentation](./semconv/v1.36.0/MIGRATION.md) for information on how to
upgrade from `go.opentelemetry.io/otel/semconv/v1.34.0.`(#7032, #7041)
- Add support for configuring Prometheus name translation using
`WithTranslationStrategy` option in
`go.opentelemetry.io/otel/exporters/prometheus`. The current default
translation strategy when UTF-8 mode is enabled is
`NoUTF8EscapingWithSuffixes`, but a future release will change the
default strategy to `UnderscoreEscapingWithSuffixes` for compliance with
the specification. (#7111)
- Add experimental self-observability log metrics in
`go.opentelemetry.io/otel/sdk/log`. Check the
`go.opentelemetry.io/otel/sdk/log/internal/x` package documentation for
more information. (#7121)
- Add experimental self-observability trace exporter metrics in
`go.opentelemetry.io/otel/exporters/stdout/stdouttrace`. Check the

`go.opentelemetry.io/otel/sdk/trace`. (#6791)
- Change `AssertEqual` in `go.opentelemetry.io/otel/log/logtest` to
accept `TestingT` in order to support benchmarks and fuzz tests. (#6908)
- Change `DefaultExemplarReservoirProviderSelector` in
`go.opentelemetry.io/otel/sdk/metric` to use `runtime.GOMAXPROCS(0)`
instead of `runtime.NumCPU()` for the `FixedSizeReservoirProvider`
default size. (#7094)
### Fixed
- `SetBody` method of `Record` in `go.opentelemetry.io/otel/sdk/log` now
deduplicates key-value collections (`log.Value` of `log.KindMap` from
`go.opentelemetry.io/otel/log`). (#7002)
- Fix `go.opentelemetry.io/otel/exporters/prometheus` to not append a
suffix if it's already present in metric name. (#7088)
- Fix the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace`
self-observability component type and name. (#7195)
- Fix partial export count metric in
`go.opentelemetry.io/otel/exporters/stdout/stdouttrace`. (#7199)

information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.32.0.`(#6799)
- The `go.opentelemetry.io/otel/semconv/v1.34.0` package.

- Add metric's schema URL as `otel_scope_schema_url` label in
`go.opentelemetry.io/otel/exporters/prometheus`. (#5947)
- Add metric's scope attributes as `otel_scope_[attribute]` labels in

- Add `EventName` to `EnabledParameters` in
`go.opentelemetry.io/otel/log`. (#6825)
- Add `EventName` to `EnabledParameters` in
`go.opentelemetry.io/otel/sdk/log`. (#6825)

compatibility in `go.opentelemetry.io/otel/exporters/prometheus`.
(#6822)
- Context cancellation during metric pipeline produce does not corrupt
data in `go.opentelemetry.io/otel/sdk/metric`. (#6914)
### Removed

`otel_scope_info` metric. (#6770)
# Overview
Closes https://github.com/open-telemetry/opentelemetry-go/issues/6786
### Added
- Add exponential histogram support in
`go.opentelemetry.io/otel/exporters/prometheus`. (#6421)
- The `go.opentelemetry.io/otel/semconv/v1.31.0` package.
The package contains semantic conventions from the `v1.31.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.31.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.30.0`. (#6479)
- Add `Recording`, `Scope`, and `Record` types in
`go.opentelemetry.io/otel/log/logtest`. (#6507)
- Add `WithHTTPClient` option to configure the `http.Client` used by
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#6751)
- Add `WithHTTPClient` option to configure the `http.Client` used by
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#6752)
- Add `WithHTTPClient` option to configure the `http.Client` used by
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6688)
- Add `ValuesGetter` in `go.opentelemetry.io/otel/propagation`, a
`TextMapCarrier` that supports retrieving multiple values for a single
key. (#5973)
- Add `Values` method to `HeaderCarrier` to implement the new
`ValuesGetter` interface in `go.opentelemetry.io/otel/propagation`.
(#5973)
- Update `Baggage` in `go.opentelemetry.io/otel/propagation` to retrieve
multiple values for a key when the carrier implements `ValuesGetter`.
(#5973)
- Add `AssertEqual` function in `go.opentelemetry.io/otel/log/logtest`.
(#6662)
- The `go.opentelemetry.io/otel/semconv/v1.32.0` package.
The package contains semantic conventions from the `v1.32.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.32.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.31.0`(#6782)
- Add `Transform` option in `go.opentelemetry.io/otel/log/logtest`.
(#6794)
- Add `Desc` option in `go.opentelemetry.io/otel/log/logtest`. (#6796)
### Removed
- Drop support for [Go 1.22]. (#6381, #6418)
- Remove `Resource` field from `EnabledParameters` in
`go.opentelemetry.io/otel/sdk/log`. (#6494)

- Remove `AssertRecordEqual` function in
`go.opentelemetry.io/otel/log/logtest`, use `AssertEqual` instead.
(#6662)
### Changed
- ⚠️ Update `github.com/prometheus/client_golang` to `v1.21.1`, which
changes the `NameValidationScheme` to `UTF8Validation`.
This allows metrics names to keep original delimiters (e.g. `.`), rather
than replacing with underscores.
This can be reverted by setting
`github.com/prometheus/common/model.NameValidationScheme` to
`LegacyValidation` in `github.com/prometheus/common/model`. (#6433)
- Initialize map with `len(keys)` in `NewAllowKeysFilter` and
`NewDenyKeysFilter` to avoid unnecessary allocations in

- `go.opentelemetry.io/otel/log/logtest` is now a separate Go module.
(#6465)
- `go.opentelemetry.io/otel/sdk/log/logtest` is now a separate Go
module. (#6466)
- `Recorder` in `go.opentelemetry.io/otel/log/logtest` no longer
separately stores records emitted by loggers with the same
instrumentation scope. (#6507)
- Improve performance of `BatchProcessor` in
`go.opentelemetry.io/otel/sdk/log` by not exporting when exporter cannot
accept more. (#6569, #6641)
### Deprecated
- Deprecate support for `model.LegacyValidation` for
`go.opentelemetry.io/otel/exporters/prometheus`. (#6449)
### Fixes
- Stop percent encoding header environment variables in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` and
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6392)
- Ensure the `noopSpan.tracerProvider` method is not inlined in
`go.opentelemetry.io/otel/trace` so the `go.opentelemetry.io/auto`
instrumentation can instrument non-recording spans. (#6456)
- Use a `sync.Pool` instead of allocating `metricdata.ResourceMetrics`
in `go.opentelemetry.io/otel/exporters/prometheus`. (#6472)

## Overview
This release is the last to support [Go 1.22].
The next release will require at least [Go 1.23].
### Added
- Add `ValueFromAttribute` and `KeyValueFromAttribute` in
`go.opentelemetry.io/otel/log`. (#6180)
- Add `EventName` and `SetEventName` to `Record` in
`go.opentelemetry.io/otel/log`. (#6187)
- Add `EventName` to `RecordFactory` in
`go.opentelemetry.io/otel/log/logtest`. (#6187)
- `AssertRecordEqual` in `go.opentelemetry.io/otel/log/logtest` checks
`Record.EventName`. (#6187)
- Add `EventName` and `SetEventName` to `Record` in
`go.opentelemetry.io/otel/sdk/log`. (#6193)
- Add `EventName` to `RecordFactory` in
`go.opentelemetry.io/otel/sdk/log/logtest`. (#6193)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#6211)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#6211)
- Emit `Record.EventName` field in
`go.opentelemetry.io/otel/exporters/stdout/stdoutlog` (#6210)
- The `go.opentelemetry.io/otel/semconv/v1.28.0` package.
The package contains semantic conventions from the `v1.28.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.28.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.27.0`(#6236)
- The `go.opentelemetry.io/otel/semconv/v1.30.0` package.
The package contains semantic conventions from the `v1.30.0` version of
the OpenTelemetry Semantic Conventions.
See the [migration documentation](./semconv/v1.30.0/MIGRATION.md) for
information on how to upgrade from
`go.opentelemetry.io/otel/semconv/v1.28.0`(#6240)
- Document the pitfalls of using `Resource` as a comparable type.
`Resource.Equal` and `Resource.Equivalent` should be used instead.
(#6272)
- Support [Go 1.24]. (#6304)
- Add `FilterProcessor` and `EnabledParameters` in
`go.opentelemetry.io/otel/sdk/log`.
It replaces
`go.opentelemetry.io/otel/sdk/log/internal/x.FilterProcessor`.
Compared to previous version it additionally gives the possibility to
filter by resource and instrumentation scope. (#6317)
### Changed
- Update `github.com/prometheus/common` to v0.62.0., which changes the
`NameValidationScheme` to `NoEscaping`. This allows metrics names to
keep original delimiters (e.g. `.`), rather than replacing with
underscores. This is controlled by the `Content-Type` header, or can be
reverted by setting `NameValidationScheme` to `LegacyValidation` in
`github.com/prometheus/common/model`. (#6198)
### Fixes
- Eliminate goroutine leak for the processor returned by
`NewSimpleSpanProcessor` when `Shutdown` is called and the passed `ctx`
is canceled and `SpanExporter.Shutdown` has not returned. (#6368)
- Eliminate goroutine leak for the processor returned by
`NewBatchSpanProcessor` when `ForceFlush` is called and the passed `ctx`
is canceled and `SpanExporter.Export` has not returned. (#6369)

## Overview
### Changed
- Remove the notices from `Logger` to make the whole Logs API
user-facing in `go.opentelemetry.io/otel/log`. (#6167)
### Fixed
- Relax minimum Go version to 1.22.0 in various modules. (#6073)
- The `Type` name logged for the
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` client
is corrected from `otlphttpgrpc` to `otlptracegrpc`. (#6143)
- The `Type` name logged for the
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlphttpgrpc` client
is corrected from `otlphttphttp` to `otlptracehttp`. (#6143)
### Added
- Add `Reset` method to `SpanRecorder` in
`go.opentelemetry.io/otel/sdk/trace/tracetest`. (#5994)
- Add `EnabledInstrument` interface in
`go.opentelemetry.io/otel/sdk/metric/internal/x`. This is an
experimental interface that is implemented by synchronous instruments
provided by `go.opentelemetry.io/otel/sdk/metric`. Users can use it to
avoid performing computationally expensive operations when recording
measurements. It does not fall within the scope of the OpenTelemetry Go
versioning and stability [policy](./VERSIONING.md) and it may be changed
in backwards incompatible ways or removed in feature releases. (#6016)
### Changed
- The default global API now supports full auto-instrumentation from the
`go.opentelemetry.io/auto` package. See that package for more
information. (#5920)
- Propagate non-retryable error messages to client in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#5929)

`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#5929)
- Propagate non-retryable error messages to client in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#5929)
- Performance improvements for attribute value `AsStringSlice`,
`AsFloat64Slice`, `AsInt64Slice`, `AsBoolSlice`. (#6011)
- Change `EnabledParameters` to have a `Severity` field instead of a
getter and setter in `go.opentelemetry.io/otel/log`. (#6009)
### Fixed
- Fix inconsistent request body closing in
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#5954)
- Fix inconsistent request body closing in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`.
(#5954)
- Fix inconsistent request body closing in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`.
(#5954)
- Fix invalid exemplar keys in
`go.opentelemetry.io/otel/exporters/prometheus`. (#5995)
- Fix attribute value truncation in
`go.opentelemetry.io/otel/sdk/trace`. (#5997)
- Fix attribute value truncation in `go.opentelemetry.io/otel/sdk/log`.
(#6032)
### Added
- Add `go.opentelemetry.io/otel/sdk/metric/exemplar.AlwaysOffFilter`,
which can be used to disable exemplar recording. (#5850)
- Add `go.opentelemetry.io/otel/sdk/metric.WithExemplarFilter`, which
can be used to configure the exemplar filter used by the metrics SDK.
(#5850)

require at least [Go 1.22].
### Added
- Add MacOS ARM64 platform to the compatibility testing suite. (#5577)
- Add `InstrumentationScope` field to `SpanStub` in
`go.opentelemetry.io/otel/sdk/trace/tracetest`, as a replacement for the
deprecated `InstrumentationLibrary`. (#5627)
- Make the initial release of
`go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. This new
module contains an OTLP exporter that transmits log telemetry using
gRPC. This module is unstable and breaking changes may be introduced.
See our [versioning policy](VERSIONING.md) for more information about
these stability guarantees. (#5629)
- Add `Walk` function to `TraceState` in
`go.opentelemetry.io/otel/trace` to iterate all the key-value pairs.

experimental interface that log `Processor`s can implement to instruct
the `Logger` if a `Record` will be processed or not. It replaces the
existing `Enabled` method that is removed from the `Processor` interface
itself. It does not fall within the scope of the OpenTelemetry Go
versioning and stability [policy](./VERSIONING.md) and it may be changed
in backwards incompatible ways or removed in feature releases. (#5692)
- Support [Go 1.23]. (#5720)
### Changed
- `NewMemberRaw`, `NewKeyProperty` and `NewKeyValuePropertyRaw` in
`go.opentelemetry.io/otel/baggage` allow UTF-8 string in key. (#5132)
- `Processor.OnEmit` in `go.opentelemetry.io/otel/sdk/log` now accepts a
pointer to `Record` instead of a value so that the record modifications
done in a processor are propagated to subsequent registered processors.
(#5636)
- `SimpleProcessor.Enabled` in `go.opentelemetry.io/otel/sdk/log` now
returns `false` if the exporter is `nil`. (#5665)
- Update the concurrency requirements of `Exporter` in
`go.opentelemetry.io/otel/sdk/log`. (#5666)
- `SimpleProcessor` in `go.opentelemetry.io/otel/sdk/log` synchronizes
`OnEmit` calls. (#5666)
- The `Processor` interface in `go.opentelemetry.io/otel/sdk/log` no
longer includes the `Enabled` method. See the `FilterProcessor`
interface type added in `go.opentelemetry.io/otel/sdk/log/internal/x` to
continue providing this functionality. (#5692)
- The `SimpleProcessor` type in `go.opentelemetry.io/otel/sdk/log` is no
longer comparable. (#5693)
- The `BatchProcessor` type in `go.opentelemetry.io/otel/sdk/log` is no
longer comparable. (#5693)
### Fixed

(#5641)
- Correct comments for the priority of the `WithEndpoint` and
`WithEndpointURL` options and their corresponding environment variables
in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`.
(#5650)
- Stop percent encoding header environment variables in

(#5705)
- Remove invalid environment variable header keys in
`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`,

zero-allocation log processing using `SimpleProcessor`. (#5493)
- Use non-generic functions in the `Start` method of
`"go.opentelemetry.io/otel/sdk/trace".Trace` to reduce memory
allocation. (#5497)
