 ## [Unreleased]
 
+## [1.28.0/0.50.0/0.4.0] 2024-07-02
+
+### Added
+
+- The `IsEmpty` method is added to the `Instrument` type in `go.opentelemetry.io/otel/sdk/metric`.
+  This method is used to check if an `Instrument` instance is a zero-value. (#5431)
+- Store and provide the emitted `context.Context` in `ScopeRecords` of `go.opentelemetry.io/otel/sdk/log/logtest`. (#5468)
+- The `go.opentelemetry.io/otel/semconv/v1.26.0` package.
+  The package contains semantic conventions from the `v1.26.0` version of the OpenTelemetry Semantic Conventions. (#5476)
+- The `AssertRecordEqual` method to `go.opentelemetry.io/otel/log/logtest` to allow comparison of two log records in tests. (#5499)
+- The `WithHeaders` option to `go.opentelemetry.io/otel/exporters/zipkin` to allow configuring custom http headers while exporting spans. (#5530)
+
+### Changed
+
+- `Tracer.Start` in `go.opentelemetry.io/otel/trace/noop` no longer allocates a span for empty span context. (#5457)
+- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to `go.opentelemetry.io/otel/semconv/v1.26.0` in `go.opentelemetry.io/otel/example/otel-collector`. (#5490)
+- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to `go.opentelemetry.io/otel/semconv/v1.26.0` in `go.opentelemetry.io/otel/example/zipkin`. (#5490)
+- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to `go.opentelemetry.io/otel/semconv/v1.26.0` in `go.opentelemetry.io/otel/exporters/zipkin`. (#5490)
+  - The exporter no longer exports the deprecated "otel.library.name" or "otel.library.version" attributes.
+- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to `go.opentelemetry.io/otel/semconv/v1.26.0` in `go.opentelemetry.io/otel/sdk/resource`. (#5490)
+- Upgrade `go.opentelemetry.io/otel/semconv/v1.25.0` to `go.opentelemetry.io/otel/semconv/v1.26.0` in `go.opentelemetry.io/otel/sdk/trace`. (#5490)
+- `SimpleProcessor.OnEmit` in `go.opentelemetry.io/otel/sdk/log` no longer allocates a slice which makes it possible to have a 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)
+- `service.instance.id` is populated for a `Resource` created with `"go.opentelemetry.io/otel/sdk/resource".Default` with a default value when `OTEL_GO_X_RESOURCE` is set. (#5520)
+- Improve performance of metric instruments in `go.opentelemetry.io/otel/sdk/metric` by removing unnecessary calls to `time.Now`. (#5545)
+
+### Fixed
+
+- Log a warning to the OpenTelemetry internal logger when a `Record` in `go.opentelemetry.io/otel/sdk/log` drops an attribute due to a limit being reached. (#5376)
+- Identify the `Tracer` returned from the global `TracerProvider` in `go.opentelemetry.io/otel/global` with its schema URL. (#5426)
+- Identify the `Meter` returned from the global `MeterProvider` in `go.opentelemetry.io/otel/global` with its schema URL. (#5426)
+- Log a warning to the OpenTelemetry internal logger when a `Span` in `go.opentelemetry.io/otel/sdk/trace` drops an attribute, event, or link due to a limit being reached. (#5434)
+- Document instrument name requirements in `go.opentelemetry.io/otel/metric`. (#5435)
+- Prevent random number generation data-race for experimental rand exemplars in `go.opentelemetry.io/otel/sdk/metric`. (#5456)
+- Fix counting number of dropped attributes of `Record` in `go.opentelemetry.io/otel/sdk/log`. (#5464)
+- Fix panic in baggage creation when a member contains `0x80` char in key or value. (#5494)
+- Correct comments for the priority of the `WithEndpoint` and `WithEndpointURL` options and their corresponding environment variables in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`. (#5508)
+- Retry trace and span ID generation if it generated an invalid one in `go.opentelemetry.io/otel/sdk/trace`. (#5514)
+- Fix stale timestamps reported by the last-value aggregation. (#5517)
+- Indicate the `Exporter` in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp` must be created by the `New` method. (#5521)
+- Improved performance in all `{Bool,Int64,Float64,String}SliceValue` functions of `go.opentelemetry.io/attributes` by reducing the number of allocations. (#5549)
+

+
+### Added
+
+- Add example for `go.opentelemetry.io/otel/exporters/stdout/stdoutlog`. (#5242)

+- The count of dropped records from the `BatchProcessor` in `go.opentelemetry.io/otel/sdk/log` is logged. (#5276)
+- Add metrics in the `otel-collector` example. (#5283)
+- Add the synchronous gauge instrument to `go.opentelemetry.io/otel/metric`. (#5304)
+  - An `int64` or `float64` synchronous gauge instrument can now be created from a `Meter`.
+  - All implementations of the API (`go.opentelemetry.io/otel/metric/noop`, `go.opentelemetry.io/otel/sdk/metric`) are updated to support this instrument.
+- Add logs to `go.opentelemetry.io/otel/example/dice`. (#5349)
+

+- De-duplicate map attributes added to a `Record` in `go.opentelemetry.io/otel/sdk/log`. (#5230)
+- `go.opentelemetry.io/otel/exporters/stdout/stdoutlog` won't print timestamps when `WithoutTimestamps` option is set. (#5241)
+- The `go.opentelemetry.io/otel/exporters/stdout/stdoutlog` exporter won't print `AttributeValueLengthLimit` and `AttributeCountLimit` fields now, instead it prints the `DroppedAttributes` field. (#5272)

+- 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)

+- 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)

+# Experimental Features
+
+The SDK contains features that have not yet stabilized in the OpenTelemetry specification.
+These features are added to the OpenTelemetry Go SDK prior to stabilization in the specification so that users can start experimenting with them and provide feedback.
+
+These feature may change in backwards incompatible ways as feedback is applied.
+See the [Compatibility and Stability](#compatibility-and-stability) section for more information.
+
+## Features
+
+- [Resource](#resource)
+
+### Resource
+
+[OpenTelemetry resource semantic conventions] include many attribute definitions that are defined as experimental.
+To have experimental semantic conventions be added by [resource detectors] set the `OTEL_GO_X_RESOURCE` environment variable.
+The value set must be the case-insensitive string of `"true"` to enable the feature.
+All other values are ignored.
+
+<!-- TODO: document what attributes are added by which detector -->
+
+[OpenTelemetry resource semantic conventions]: https://opentelemetry.io/docs/specs/semconv/resource/
+[resource detectors]: https://pkg.go.dev/go.opentelemetry.io/otel/sdk/resource#Detector
+
+#### Examples
+
+Enable experimental resource semantic conventions.
+
+```console
+export OTEL_GO_X_RESOURCE=true
+```
+
+Disable experimental resource semantic conventions.
+
+```console
+unset OTEL_GO_X_RESOURCE
+```
+
+## Compatibility and Stability
+
+Experimental features do not fall within the scope of the OpenTelemetry Go versioning and stability [policy](../../../VERSIONING.md).
+These features may be removed or modified in successive version releases, including patch versions.
+
+When an experimental feature is promoted to a stable feature, a migration path will be included in the changelog entry of the release.
+There is no guarantee that any environment variable feature flags that enabled the experimental feature will be supported by the stable version.
+If they are supported, they may be accompanied with a deprecation notice stating a timeline for the removal of that support.
