An automatic upgrade of PI Cloud Connect occurred on June 7th, 2017.
With this release publishers will now listen for and send PI Point changes as they occur. There is also a fix to a rare edge case where publishers miss some data to send after recovering from being unable to contact the source Data Archive for some time.
Following the upcoming upgrade the next automatic upgrade is tentatively scheduled for the week of July 3rd.
The automatic upgrade process does not require any manual interaction and will only incur a momentary delay in data. If for any reason your automatic upgrade fails you will receive an email with machine specific details and guidance on how to manually upgrade the local service.
