CURRENT

Value: 3

The targets reflect all changes committed before the targets were added to the stream.

This will be sent after or with a read_time that is greater than or equal to the time at which the targets were added. Listeners can wait for this change if read-after-write semantics are desired.

After the initial state is complete, CURRENT will be returned even if the target was previously indicated to be CURRENT.
