+## [1.32.0/0.54.0/0.8.0/0.0.11] 2024-11-08
+
+### 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)
+- Add `ExemplarReservoirProviderSelector` and `DefaultExemplarReservoirProviderSelector` to `go.opentelemetry.io/otel/sdk/metric`, which defines the exemplar 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 the OpenTelemetry Semantic Conventions. (#5894)
+- Add `Attributes attribute.Set` field to `Scope` in `go.opentelemetry.io/otel/sdk/instrumentation`. (#5903)
+- Add `Attributes attribute.Set` field to `ScopeRecords` in `go.opentelemetry.io/otel/log/logtest`. (#5927)
+- `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` adds instrumentation scope attributes. (#5934)
+- `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` adds instrumentation scope attributes. (#5934)
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` adds instrumentation scope attributes. (#5935)
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` adds instrumentation scope attributes. (#5935)
+- `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` adds instrumentation scope attributes. (#5933)
+- `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` adds instrumentation scope attributes. (#5933)
+- `go.opentelemetry.io/otel/exporters/prometheus` adds instrumentation scope attributes in `otel_scope_info` metric as labels. (#5932)
+
+### Changed
+
+- Support scope attributes and make them as identifying for `Tracer` in `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`. (#5925)
+- Make schema URL and scope attributes as identifying for `Tracer` in `go.opentelemetry.io/otel/bridge/opentracing`. (#5931)
+- Clear unneeded slice elements to allow GC to collect the objects in `go.opentelemetry.io/otel/sdk/metric` and `go.opentelemetry.io/otel/sdk/trace`. (#5804)
+
+### Fixed
+
+- Global MeterProvider registration unwraps global instrument Observers, the undocumented Unwrap() methods are now private. (#5881)
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` now keeps the metadata already present in the context when `WithHeaders` is used. (#5892)
+- `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` now keeps the metadata already present in the context when `WithHeaders` is used. (#5911)
+- `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` now keeps the metadata already present in the context when `WithHeaders` is used. (#5915)
+- Fix `go.opentelemetry.io/otel/exporters/prometheus` trying to add exemplars to Gauge metrics, which is unsupported. (#5912)
+- Fix `WithEndpointURL` to always use a secure connection when an https URL is passed in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`. (#5944)
+- Fix `WithEndpointURL` to always use a secure connection when an https URL is passed in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`. (#5944)
