# Contributing to go.opentelemetry.io/auto/sdk
The `go.opentelemetry.io/auto/sdk` module is a purpose built OpenTelemetry SDK.
It is designed to be:
0. An OpenTelemetry compliant SDK
1. Instrumented by auto-instrumentation (serializable into OTLP JSON)
2. Lightweight
3. User-friendly
These design choices are listed in the order of their importance.
The primary design goal of this module is to be an OpenTelemetry SDK.
This means that it needs to implement the Go APIs found in `go.opentelemetry.io/otel`.
Having met the requirement of SDK compliance, this module needs to provide code that the `go.opentelemetry.io/auto` module can instrument.
The chosen approach to meet this goal is to ensure the telemetry from the SDK is serializable into JSON encoded OTLP.
This ensures then that the serialized form is compatible with other OpenTelemetry systems, and the auto-instrumentation can use these systems to deserialize any telemetry it is sent.
Outside of these first two goals, the intended use becomes relevant.
This package is intended to be used in the `go.opentelemetry.io/otel` global API as a default when the auto-instrumentation is running.
Because of this, this package needs to not add unnecessary dependencies to that API.
Ideally, it adds none.
It also needs to operate efficiently.
Finally, this module is designed to be user-friendly to Go development.
It hides complexity in order to provide simpler APIs when the previous goals can all still be met.

<!-- Released section --> <!-- Released section -->
<!-- Don't change this section unless doing release --> <!-- Don't change this section unless doing release -->
## [1.34.0/0.56.0/0.10.0] 2025-01-17
### Changed
- 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 is corrected from `otlphttphttp` to `otlptracehttp`. (#6143)
## [1.33.0/0.55.0/0.9.0/0.0.12] 2024-12-12
### Added
- Add `Reset` method to `SpanRecorder` in `go.opentelemetry.io/otel/sdk/trace/tracetest`. (#5994)
- Add `EnabledInstrument` interface in `go.opentelemetry.io/otel/sdk/metric/internal/x`.
This is an 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
- The default global API now supports full auto-instrumentation from the `go.opentelemetry.io/auto` package.
See that package for more information. (#5920)
- Propagate non-retryable error messages to client in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#5929)
- Propagate non-retryable error messages to client in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`. (#5929)
- Propagate non-retryable error messages to client in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`. (#5929)
- Performance improvements for attribute value `AsStringSlice`, `AsFloat64Slice`, `AsInt64Slice`, `AsBoolSlice`. (#6011)
- Change `EnabledParameters` to have a `Severity` field instead of a getter and setter in `go.opentelemetry.io/otel/log`. (#6009)
### Fixed
- Fix inconsistent request body closing in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#5954)
- Fix inconsistent request body closing in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`. (#5954)
- Fix inconsistent request body closing in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`. (#5954)
- Fix invalid exemplar keys in `go.opentelemetry.io/otel/exporters/prometheus`. (#5995)
- Fix attribute value truncation in `go.opentelemetry.io/otel/sdk/trace`. (#5997)
- Fix attribute value truncation in `go.opentelemetry.io/otel/sdk/log`. (#6032)
## [1.32.0/0.54.0/0.8.0/0.0.11] 2024-11-08

- 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` 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)

- 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)
