- The `WithView` `Option` is added to the `go.opentelemetry.io/otel/sdk/metric` package.
|
||||
This option is used to configure the view(s) a `MeterProvider` will use for all `Reader`s that are registered with it. (#3387)
|
||||
- Add Instrumentation Scope and Version as info metric and label in Prometheus exporter.
|
||||
This can be disabled using the `WithoutScopeInfo()` option added to that package.(#3273, #3357)
