## 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)
- Add template attribute functions to the
`go.opentelmetry.io/otel/semconv/v1.34.0` package. (#6939)

- `RPCGRPCRequestMetadata`
- `RPCGRPCResponseMetadata`
- Add `ErrorType` attribute helper function to the
`go.opentelmetry.io/otel/semconv/v1.34.0` package. (#6962)
- Add `WithAllowKeyDuplication` in `go.opentelemetry.io/otel/sdk/log`
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
returns a copy of the record with no shared state. (#7001)
- 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)

contains semantic conventions from the `v1.37.0` version of the
OpenTelemetry Semantic Conventions. See the [migration
documentation](./semconv/v1.37.0/MIGRATION.md) for information on how to
upgrade from `go.opentelemetry.io/otel/semconv/v1.36.0.`(#7254)
### Changed

`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

### Changed
- Retract `v0.59.0` release of
`go.opentelemetry.io/otel/exporters/prometheus` module which appends
incorrect unit suffixes. (#7046)
- Change `go.opentelemetry.io/otel/exporters/prometheus` to no longer
deduplicate suffixes when UTF8 is enabled.
It is recommended to disable unit and counter suffixes in the exporter,
and manually add suffixes if you rely on the existing behavior. (#7044)
### Fixed
- Fix `go.opentelemetry.io/otel/exporters/prometheus` to properly handle
unit suffixes when the unit is in brackets.
E.g. `{spans}`. (#7044)
### Added
- The `go.opentelemetry.io/otel/semconv/v1.33.0` package.
The package contains semantic conventions from the `v1.33.0` version of
the OpenTelemetry Semantic Conventions.

# 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)

(#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)

(#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 `RecordFactory` type from
`go.opentelemetry.io/otel/log/logtest`. (#6492)

(#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)

`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)

- 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

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

reservoir to use based on the aggregation of the metric. (#5861)
- Add `ExemplarReservoirProviderSelector` to
`go.opentelemetry.io/otel/sdk/metric.Stream` to allow using views to
configure the exemplar reservoir to use for a metric. (#5861)
- Add `ReservoirProvider`, `HistogramReservoirProvider` and
`FixedSizeReservoirProvider` to
`go.opentelemetry.io/otel/sdk/metric/exemplar` to make it convenient to
use providers of Reservoirs. (#5861)
- The `go.opentelemetry.io/otel/semconv/v1.27.0` package.
The package contains semantic conventions from the `v1.27.0` version of

`go.opentelemetry.io/otel` and `go.opentelemetry.io/otel/sdk/trace`.
(#5924)
- Support scope attributes and make them as identifying for `Meter` in
`go.opentelemetry.io/otel` and `go.opentelemetry.io/otel/sdk/metric`.
(#5926)
- Support scope attributes and make them as identifying for `Logger` in
`go.opentelemetry.io/otel` and `go.opentelemetry.io/otel/sdk/log`.

URL is passed in
`go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`.
(#5944)

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)

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)

`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`.

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)

- Improved performance in the `Stringer` implementation of
`go.opentelemetry.io/otel/baggage.Member` by reducing the number of
allocations. (#5286)
- Set the start time for last-value aggregates in
`go.opentelemetry.io/otel/sdk/metric`. (#5305)
- The `Span` in `go.opentelemetry.io/otel/sdk/trace` will record links
without span context if either non-empty `TraceState` or attributes are
provided. (#5315)
- Upgrade all dependencies of `go.opentelemetry.io/otel/semconv/v1.24.0`
to `go.opentelemetry.io/otel/semconv/v1.25.0`. (#5374)
### Fixed
- Comparison of unordered maps for
`go.opentelemetry.io/otel/log.KeyValue` and
`go.opentelemetry.io/otel/log.Value`. (#5306)
- Fix the empty output of `go.opentelemetry.io/otel/log.Value` in
`go.opentelemetry.io/otel/exporters/stdout/stdoutlog`. (#5311)
- Split the behavior of `Recorder` in
`go.opentelemetry.io/otel/log/logtest` so it behaves as a
`LoggerProvider` only. (#5365)
- Fix wrong package name of the error message when parsing endpoint URL
in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`.
(#5371)
- Identify the `Logger` returned from the global `LoggerProvider` in
`go.opentelemetry.io/otel/log/global` with its schema URL. (#5375)
