Enhancements:

• Tuned Java parameters to improve Application Server performance on large sites.
• Pay Station: When a Pay Station fails to connect to the Application Server to update a user's balance, the Pay Station now displays an error message and prints a transaction error report (if an acknowledgement printer is attached), so the user has proof that the transaction did not succeed.

Fixes:

• Added a new Admin Right to control access to the Sites tab in the Admin interface.
• Reduced the CreateSSLKeystore default certificate validity duration to not exceed 2038, to safeguard older devices running into a 2038 date rollover issue.
• macOS High Sierra (CUPS): Reduced the time it takes for a printer to be available in the Control Printer Monitoring.command script.
• Standard Release station via Site Server: Fixed an issue that caused an empty print release list for Hold/Release queue managers.
• User Client:
  • Fixed an issue that prevented the User Client from launching when the User Client icon was double-clicked in the Windows task tray.
  • Fixed an issue that caused high memory usage, especially when a high number of shared accounts are used.
  **Note: User Clients require an upgrade.
• Web Print:
  • Fixed an issue that caused the "Maximum document/file upload size" value to be ignored and set to 256MB instead.
  • Sandbox mode: Fixed an issue that caused multiple print jobs to be generated for each Web Print job in some virtual environments.
  ***Note: Web Print sandbox servers require an upgrade.
• Google Cloud Print:
  • Fixed a rare issue that caused a Google Cloud Print job to be printed multiple times.
  • Fixed an issue that sometimes prevented PaperCut MF from publishing all printers to Google Cloud Print when there were a large number of printers.
• Printer compatibility improvements:
  • RISO ComColor with PaperCut Global Print Driver: Added a new PDL transform to fix an issue that caused the printed output to have incorrect settings when printing in duplex, color, or selecting specific tray settings.
  • Canon printers on Linux and MacOS: Fixed an issue that caused an incorrect number of copies and pages to be reported for some Canon devices when using CUPS printing.
  • Epson printers: Fixed an issue that caused an incorrect number of copies and pages to be reported for some Epson printers.
  ****Note: Secondary servers require a Print Provider upgrade.

For Integrators:

• On demand Payment Gateway API: Extended the API to support external lookup on different user properties, for example card ID or alias.

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