 - `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/log` synchronously de-duplicates the passed attributes instead of delegating it to the returned `LoggerOption`. (#7266)
 - `Distinct` in `go.opentelemetry.io/otel/attribute` is no longer guaranteed to uniquely identify an attribute set. Collisions between `Distinct` values for different Sets are possible with extremely high cardinality (billions of series per instrument), but are highly unlikely. (#7175)
 - The default `TranslationStrategy` in `go.opentelemetry.io/exporters/prometheus` is changed from `otlptranslator.NoUTF8EscapingWithSuffixes` to `otlptranslator.UnderscoreEscapingWithSuffixes`. (#7421)
