## [Unreleased]
<!-- Released section -->
<!-- Don't change this section unless doing release -->
## [1.31.0/0.53.0/0.7.0/0.0.10] 2024-10-11
### Added
- Add `go.opentelemetry.io/otel/sdk/metric/exemplar` package which includes `Exemplar`, `Filter`, `TraceBasedFilter`, `AlwaysOnFilter`, `HistogramReservoir`, `FixedSizeReservoir`, `Reservoir`, `Value` and `ValueType` types. These will be used for configuring the exemplar reservoir for the metrics sdk. (#5747, #5862)
- Add `WithExportBufferSize` option to log batch processor.(#5877)
### Changed
- Enable exemplars by default in `go.opentelemetry.io/otel/sdk/metric`. Exemplars can be disabled by setting `OTEL_METRICS_EXEMPLAR_FILTER=always_off` (#5778)
- `Logger.Enabled` in `go.opentelemetry.io/otel/log` now accepts a newly introduced `EnabledParameters` type instead of `Record`. (#5791)
- `FilterProcessor.Enabled` in `go.opentelemetry.io/otel/sdk/log/internal/x` now accepts `EnabledParameters` instead of `Record`. (#5791)
- The `Record` type in `go.opentelemetry.io/otel/log` is no longer comparable. (#5847)
- Performance improvements for the trace SDK `SetAttributes` method in `Span`. (#5864)
- Reduce memory allocations for the `Event` and `Link` lists in `Span`. (#5858)
- Performance improvements for the trace SDK `AddEvent`, `AddLink`, `RecordError` and `End` methods in `Span`. (#5874)
### Deprecated
- Deprecate all examples under `go.opentelemetry.io/otel/example` as they are moved to [Contrib repository](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/examples). (#5854)
### Fixed
- The race condition for multiple `FixedSize` exemplar reservoirs identified in #5814 is resolved. (#5819)
- Fix log records duplication in case of heterogeneous resource attributes by correctly mapping each log record to it's resource and scope. (#5803)
- Fix timer channel drain to avoid hanging on Go 1.23. (#5868)
- Fix delegation for global meter providers, and panic when calling otel.SetMeterProvider. (#5827)
- Change the `reflect.TypeOf` to use a nil pointer to not allocate on the heap unless necessary. (#5827)
## [1.30.0/0.52.0/0.6.0/0.0.9] 2024-09-09
### Added
- Support `OTEL_EXPORTER_OTLP_LOGS_INSECURE` and `OTEL_EXPORTER_OTLP_INSECURE` environments in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#5739)
- The `WithResource` option for `NewMeterProvider` now merges the provided resources with the ones from environment variables. (#5773)
- The `WithResource` option for `NewLoggerProvider` now merges the provided resources with the ones from environment variables. (#5773)
- Add UTF-8 support to `go.opentelemetry.io/otel/exporters/prometheus`. (#5755)
### Fixed
- Fix memory leak in the global `MeterProvider` when identical instruments are repeatedly created. (#5754)
- Fix panic on instruments creation when setting meter provider. (#5758)
- Fix an issue where `SetMeterProvider` in `go.opentelemetry.io/otel` might miss the delegation for instruments and registries. (#5780)
### Removed
- Drop support for [Go 1.21]. (#5736, #5740, #5800)
## [1.29.0/0.51.0/0.5.0] 2024-08-23
This release is the last to support [Go 1.21].
The next release will 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. (#5651)
- Bridge the trace state in `go.opentelemetry.io/otel/bridge/opencensus`. (#5651)
- Zero value of `SimpleProcessor` in `go.opentelemetry.io/otel/sdk/log` no longer panics. (#5665)
- The `FilterProcessor` interface type is added in `go.opentelemetry.io/otel/sdk/log/internal/x`.
This is an optional and 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
- Correct comments for the priority of the `WithEndpoint` and `WithEndpointURL` options and their corresponding environment variables in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`. (#5584)
- Pass the underlying error rather than a generic retry-able failure in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`, `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` and `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`. (#5541)
- Correct the `Tracer`, `Meter`, and `Logger` names used in `go.opentelemetry.io/otel/example/dice`. (#5612)
- Correct the `Tracer` names used in `go.opentelemetry.io/otel/example/namedtracer`. (#5612)
- Correct the `Tracer` name used in `go.opentelemetry.io/otel/example/opencensus`. (#5612)

- 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 `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`, `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`, `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` and `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` (#5705)
- Remove invalid environment variable header keys in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`, `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`, `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` and `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` (#5705)
### Removed
- The `Enabled` method of the `SimpleProcessor` in `go.opentelemetry.io/otel/sdk/log` is removed. (#5692)
- The `Enabled` method of the `BatchProcessor` in `go.opentelemetry.io/otel/sdk/log` is removed. (#5692)

// Therefore, it is recommended that name is the Go package name of the

// therefore, the WithInstrumentationVersion option should be used to
// distinguish these different codebases. Additionally, instrumentation

// this is the case, the WithScopeAttributes option should be used to
// uniquely identify Tracers that handle the different domains of workflow
// data.
//
// If the same name and options are passed multiple times, the same Tracer
// will be returned (it is up to the implementation if this will be the
