Breaking changes

Datastore discovery

The output format of the vmware.datastore.discovery item has been changed. Returned JSON no longer contains the “data” object. Now the item returns a normal JSON containing an array, thus allowing to apply item value preprocessing steps directly to the returned data without additional workarounds.

Old JSON format New JSON format
{"data":[{"{#DATASTORE}":"FOO",...},{"{#DATASTORE}":"BAR",...}]} [{“{#DATASTORE}”:“FOO”,…},{“{#DATASTORE}”:“BAR”,…}]
