@@ -40,6 +40,7 @@ This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.htm
- The `ExportSpans` method of the`SpanExporter` interface type was updated to accept `ReadOnlySpan`s instead of the removed `SpanSnapshot`.
This brings the export interface into compliance with the specification in that it now accepts an explicitly immutable type instead of just an implied one. (#1873)
- Unembed `SpanContext` in `Link`. (#1877)
- Semantic conventions are now generated from the specification YAML. (#1891)
- Spans created by the global `Tracer` obtained from `go.opentelemetry.io/otel`, prior to a functioning `TracerProvider` being set, now propagate the span context from their parent if one exists. (#1901)
- Move the `go.opentelemetry.io/otel/unit` package to `go.opentelemetry.io/otel/metric/unit`. (#1903)

# Release Process
## Semantic Convention Generation
If a new version of the OpenTelemetry Specification has been released it will be necessary to generate a new
semantic convention package from the YAML definitions in the specification repository. There is a utility in
`internal/tools/semconv-gen` that can be used to generate the `semconv` package. This will ideally be done
shortly after the specification release is tagged, but it is also good practice to ensure that current conventions
are current before creating a release tag.
There are currently two categories of semantic conventions that must be generated, `resource` and `trace`.
```
cd internal/tools/semconv-gen
go run generate.go -i /path/to/specification/repo/semantic_conventions/resource
go run generate.go -i /path/to/specification/repo/semantic_conventions/trace
```
Using default values for all options other than `input` will result in using the `template.j2` template to
generate `resource.go` and `trace.go` in `/path/to/otelgo/repo/semconv`.
## Pre-Release
Update go.mod for submodules to depend on the new release which will happen in the next step.
