Enhancements

• Improved Application Server performance by optimizing the Application Server to Print Provider protocol. [PO-3047], [PO-3042], [PO-3052]
• Added the ability to turn off full-site server sync via a new config key: system.site.database.rebuild.enabled. Incremental syncs will not be impacted by this. [PO-3033]

Fixes

• Fixed an issue that stopped empty printer groups from being removed in the nightly maintenance sync. [PO-3007]
• Fixed a performance issue when releasing a large number of print jobs simultaneously. [PO-3112]
• Fixed a HTTP ERROR 500:Unable to resolve expression "mailto" error that appeared in the web interface when applying a perpetual license with a negative number of Site Servers in the Global Entitlements Service. Solving out known issue PO-3065.

Print Provider

• Fixed an issue that caused the PaperCut Application Server to incorrectly detect monochrome printers as color printers, which could lead to incorrect print charging or policy enforcement. [PIE-842]
• Improved the Print Provider to reduce the Application Server load when there are a large number of held jobs in a Find-Me queue and the connection between the Print Provider and the App Server if disrupted and then restored. [PIE-872]
