### 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)

Part of #5249.
Addresses #5249 (comment)
This removes handling of the
OTEL_GO_X_EXEMPLARenvironment variable.Instead of changing the default for the existing environment variable to enable it by default, i'm just removing it entirely. Users can still disable the feature by setting the filter to always_off. Since we will continue to support that configuration, it seems better to direct users there, rather than give them a temporary equivalent.
