### Changed

- Convert process metric instruments in `go.opentelemetry.io/otel/semconv/v1.40.0/processconv` to Observable variants (`Int64ObservableCounter`, `Int64ObservableGauge`, `Int64ObservableUpDownCounter`, `Float64ObservableGauge`) to align with how process-level metrics are collected via OS callbacks. (#7342)
- `ErrorType` in `go.opentelemetry.io/otel/semconv` now unwraps errors created with `fmt.Errorf` when deriving the `error.type` attribute. (#8133)
- `go.opentelemetry.io/otel/sdk/log` now unwraps error chains created with `fmt.Errorf` when deriving the `error.type` attribute from errors on log records. (#8133)
- `Set.MarshalLog` method in `go.opentelemetry.io/otel/attribute` now uses `Value.String` formatting following the [OpenTelemetry AnyValue representation for non-OTLP protocols](https://opentelemetry.io/docs/specs/otel/common/#anyvalue). (#8169)
