-### Feature gate configurations
-
-#### Transition from metrics with "direction" attribute
-
-The proposal to change metrics from being reported with a `direction` attribute has been reverted in the specification. As a result, the
-following feature gates will be removed in v0.62.0:
-
-- **receiver.vcenterreceiver.emitMetricsWithoutDirectionAttribute**
-- **receiver.vcenterreceiver.emitMetricsWithDirectionAttribute**
