Significant Changes

Time unit for scheduled_duration and queued_duration changed (#37936)

scheduled_duration and queued_duration metrics are now emitted in milliseconds instead of seconds.

By convention all statsd metrics should be emitted in milliseconds, this is later expected in e.g. prometheus statsd-exporter.

Support for OpenTelemetry Metrics is no longer "Experimental" (#40286)

Experimental support for OpenTelemetry was added in 2.7.0 since then fixes and improvements were added and now we announce the feature as stable.
