Fixes:

• macOS High Sierra (CUPS): Fixed an issue triggered by a recent macOS High Sierra update, causing a delay in the display and monitoring of printers after installation, and when a new printer is subsequently added.
• macOS and Linux: Fixed a rare issue that sometimes failed to update the printer status and logged a pc-event-monitor error on the print-provider.log, when one or more printers had unresolvable hostnames.

Other Notes:

• If you are running v17.2.1 or later, there is NO database upgrade.
